MTPU Kids Yoga Mat is a healthy exercise equipment, yoga voice meditation, yoga diet and yoga postures can lay the foundation for children to live a healthy and happy life, so that every child will be ready to deal with the various challenges that they will face in life tools, knowledge and good habits. Children are not only energetic and active, but also imaginative, so learning age-appropriate yoga poses can be fun for them. Practicing yoga poses can develop balance and coordination, strength and flexibility in children, allowing children to improve focus, develop imagination, and learn to regulate stress. Authorities in every field disapprove of infant yoga poses. Throughout the ages, all the authoritative teachers of yoga have never approved or recommended yoga postures for babies. The yoga point of view believes that babies can develop lively and strong only by relying on their natural movements. Trying to force babies into unnatural positions can injure them. Likewise, the American Academy of Pediatrics (AAP) is against giving physical activity classes to babies. Dr. Eric, chairman of the American Academy of Pediatrics Committee on Sports Medicine and Wellness, said: "Babies' fragile bones can be damaged when they are forced into unnatural positions." The damage can even last a lifetime. negative impact. Therefore, parents should remember that babies will grow up healthily through their natural and natural movements. Parents who want to establish a close relationship with their babies can sing transcendental yoga voices to their babies, including group yoga voice meditation with their babies. From ancient times to the present, yoga views agree that yoga voice meditation is suitable for children of all ages to practice. As for other internal forms of practice, such as mind awareness and yoga relaxation, as long as the child is mature enough to understand and practice. Many of the poses in yoga are especially suitable for energetic children who will enjoy a personal play on the body that will benefit both their body and mind, and the various poses have been specially selected for children to really enjoy The fun of yoga practice. The main purpose of adult yoga is to train the coordination and flexibility of the body, while the body flexibility of young children is relatively strong. Their yoga goal is not to "cultivate the body", but to "nurture the character", learn to concentrate and learn to control their own emotions. Mood, imagination, and self-confidence are some of the most important improvements a child can make from yoga training. Yoga training is mainly divided into breathing method, asana method, and meditation method. The biggest difference between adults and children is the breathing method, because children can't control their own breathing well, and it is not suitable for holding or exhaling for a long time. Their. The movements of children's yoga are specially designed. Children can easily achieve some movements that are quite difficult for adults. At the same time, children can be encouraged when they complete the movements, so that the little heart is full of pride and a sense of accomplishment .

Speech by Dr. Xiulei Jiang, the Founder and CEO of Shincell New Material
Who are we? Where do we come from? A new material company, Shincell, develops original technologies, and owns the foaming process of multi-techniques, and multi-products. The founder, me here, is the inventor of supercritical foaming technology and the inventor of anhydrous beads foaming technology. The team has a profound understanding of the basic theory of polymer semi-solid foaming and has over 10 years of experience in process control and processing equipment. The technical route we have mastered now: sheet foaming/bead foaming/3D foaming/semi-continuous sheet technology. Strategy and Opportunity Making a product is the same as being a person-it is perfect to be born at the right time and make a big difference. Our technology conforms to the trend of the times and has lasting vitality. Clean manufacturing, odorless and environmentally friendly, and recycling are the general trend of the times and are irreversible. Lightweight technology, reducing material consumption and product weight, is one of the effective technical paths to achieve the double carbon goals. Transportation (aerospace, rail transit, automobiles, ships), high-frequency and high-speed communication, CMP polishing, shoe soles, high-end packaging protection, and lightweight materials used in these fields have clear functional and technical requirements. EV batteries are a once-in-a-century wave for using #FRMPP as a buffer. Physical foaming(#SCF) has set off a technological revolution in shoe sole materials. Our positioning How to solve the contradiction between strategic focus and diversification? Single technology, single product- focusing on one technology developing, and deep digging of single market. V.S. Multiple foaming technology routes, and multiple product lines, which means excellent risk resistance. But each technology cannot be deeply developed, and one market cannot be deeply cultivated. Focus on the application and promotion of existing products or the development of new products? The essence of these two problems is the problem of resources and manpower. As long as resources and manpower are sufficient, it is not a problem at all. We can spread out and work in an all-around way in this case. But for start-up companies with limited resources and manpower, this is a question of choice, a vital one. Our product characteristics 1. All consumer products and general industrial products are #thermoplastic, #non-cross-linked, and #recyclable. 2. Various foamed polymer materials-multi product routes, MTPU/MTPEE/MPEBA/MPP/PVDF and so on. 3. Lightweight foam materials can be 100% recyclable. 4. The products are still ‘young’ and energetic. Our technical characteristics 1. Clean foaming technology 2. With high cell density, cells with micron-sized bubble structures, excellent material properties 3. Both of the technologies and products are still in the early stages of their life cycle. 4. Sheet foaming/bead foaming/3D foaming/semi-continuous sheet technology-multi-technical routes Prominent problems of intermittent sheet foaming: high labor cost and inevitable fixed loss. Where we will be in 5 years(2023-2027)? The goal of achievements in 2027, the percentage of market share, 50% for shoe sole industry 25% for automotive industry 10% for Yoga mats and sports peripheral consumer goods 10% for aviation/military industry/GMP pipeline insulation 5% for medical/food/clean packaging How to do it? 1. Continue to invest in R&D and innovation. 2. Integrate resources at hand. Do what we are best at, what others cannot do. Involve more talented people and to make sure they can serve the company in a flexible manner. 3. With the help of capital, seize the time to achieve scale expansion. 4. Detailed planning on product markets. Difficulties and challenges: 1. Technical reserve and talent reserve for continuous technological innovation. 2. Team cohesion, making sure each one of us at the right position and do what we are best at. 3. As a newly released material, the expansion of its application market is no less difficult than the technical development of the material itself. For different application markets, the time varies for large-scale use of new products. A period of 5 to 10 years is a common phenomenon. We need to find ways to break this law. To quickly introduce new products to its suitable market. 4. One new product or technology has around 3 years leading and exclusive period. After 3 years, there sure will emerge competitors. We shall take full advantage of this period to realize the rapid expansion of scale and perfect our products and technology. Objectively speaking, it is good to have competitors. On one hand, new product promotion needs more manpower. On the other hand, it will sure make us better selves and win in the competition. 5. The next 5-year plan. Summary 1. People are the core of a company, they are as important as new product promotion and technology innovation. 2. Clear marketing strategy and tactics are vital.

New Foam Material And Its Technical Characteristics
The new foam material and its technical characteristics can be summarized in the following aspects: (1) Environmentally friendly foaming materials and technologies Solving the problem of traditional freon blowing agents destroying the ozone layer has always been a hot spot in the world. In recent years, Freon alternative blowing agents with low ozone depletion potential (ODP) and global warming potential (GWP) have been vigorously developed, such as hydrochlorofluorocarbon blowing agents as second-generation blowing agents, No. Three generations of blowing agents such as hydrofluorocarbons, alkanes, carbon dioxide and other blowing agents have gradually achieved commercialization. On this basis, various Freon alternative foaming technologies have been introduced, such as HCFC-141b foaming for polyurethane, HFC-245fa foaming, cyclopentane foaming, cyclopentane-isopentane foaming, and all-water foaming. Technology such as foaming, carbon dioxide foaming, butane foaming technology for polyethylene and polystyrene, and water foaming technology for thermoplastic elastomers, silicone rubber sponge, polyethylene, polystyrene, etc., have achieved good results Effect. The emergence of new types of foaming agents such as endothermic-exothermic balanced foaming agents, microcapsule foaming agents, and masterbatch foaming agents also provides a better choice for improving the foaming effect. (2) High-performance foam materials and technologies Foam materials have the characteristics of light weight, heat insulation, and sound insulation, but to meet the application requirements in special environments, it is necessary to develop high-performance foam materials with excellent physical and mechanical properties. Flame retardant foam materials, such as flame retardant polyethylene foam, flame retardant polystyrene foam, flame retardant polyvinyl chloride foam, flame retardant polyurethane foam, flame retardant rubber and elastomer foam, etc., due to the improved flame retardant performance , In some occasions, it can meet the requirements of safety and fire prevention. The high-temperature-resistant foam material greatly broadens the temperature range of the foam material, and can work continuously for a long time in a high-temperature environment above 150-200°C, and some even have an instantaneous heat resistance of up to 540°C. Phenolic foam, epoxy foam, polymethacrylimide (PMI) foam, polyimide (PI) foam, silicone foam and other high temperature resistant foams are used as high-performance foam materials in aerospace , high-speed trains, ships, military and other special fields play an important role. Foam materials can also be modified by foaming methods, such as filling modification, reinforcement modification, binary or multi-component blending modification, copolymerization modification and nano-particle reinforcement modification, interpenetrating network technology, etc., to significantly improve a certain aspect. Or comprehensive mechanical properties. (3) Functional foaming materials and technology In addition to common packaging, construction, thermal insulation and other fields, foam materials with special properties play an important role as functional materials in special occasions. For example, antistatic foams are used as packaging materials for electronic components and equipment, wave-absorbing foams are used as stealth materials for absorbing electromagnetic waves and anti-radar detection, biodegradable foams are used as cell scaffold materials in medical tissue engineering, Deuterated polystyrene foam and poly-4-methyl-1-pentene (PMP) ultra-low density foam used as various target materials in inertial confinement fusion (ICF) research, polyimide with nanoscale pore size Amine foams are used in the microelectronics industry as insulating materials with ultra-low dielectric constants, among others. Foam materials with an open cell structure are used as functional materials in terms of filtration, water passage, and ventilation. Typical open-cell functional foam materials also include water-absorbent and hydrophilic foam plastics, oil-absorbent foam plastics used to deal with marine oil spills, sound-absorbing foam materials used to eliminate noise pollution and improve the silent ability of submarines, used for Foam plastics for reducing chemical fertilizers, foam plastics with antibacterial and deodorizing functions, foam plastics that can absorb formaldehyde, and foam plastics with gas purification functions, etc. In addition, reticulated polyurethane foam, which is different from ordinary open-cell foam, plays a unique role in fire prevention and explosion suppression in fuel tanks of military equipment such as aircraft, ships and tanks. (4) Degradation and recycling of foamed materials In order to eliminate "white pollution", foam materials with photo-biodegradability and biodegradability have been developed rapidly. Such as biodegradable foaming materials represented by polylactic acid (PLA) and polyhydroxybutyrate (PHB), as well as biodegradable foaming materials of natural polymers such as starch and plant fibers. Polypropylene foam material, as an environmentally adaptable foam material with high heat resistance and excellent physical and mechanical properties, has also been favored by people and has become a hot spot of research and development at home and abroad. On the other hand, the recycling of waste foam materials is an important way to reduce resource waste, rationally utilize energy, and protect the environment. The resource recycling technology of waste foam materials has been further developed, such as mixing waste foam materials with cement, concrete, fly ash, etc. to make various lightweight building composite materials, or through simple regeneration, granulation, and modified coating And various chemical raw materials such as paints, cracking and recycling, etc., have improved the recycling efficiency of waste foam materials. In addition, the foaming technology of waste recycled plastics also enables comprehensive utilization of waste plastics. (5) New foaming process and new products In addition to the traditional common extrusion, molding foaming and other processes, some new foaming processes, new products or improvements to the original technology have emerged in recent years. For example, microcellular foamed plastics prepared by supercritical fluid technology can basically maintain the basic mechanical properties of the original plastics and reduce the density of the material due to the small cell diameter and high cell density; It has unique advantages in saving materials and manufacturing large structural parts with light weight, high strength, high stiffness and good dimensional stability; low foaming profiles, structural foam synthetic wood and low foaming wood fiber/plastic composites New wood materials are of great significance in terms of resource conservation. In addition, new processes and new products such as rotomolding and foaming, crust hollow blow molding, extrusion of low-foaming blown film, biaxially stretched foamed film, microsphere composite foam, and foamed insulated coaxial cable It has been paid attention to and researched by people, and the application of ultrasonic vibration and in-situ technology in foam molding has also aroused people's great interest.

Application Prospect Of High Strength Foam Material
High-Strength foam materials are gaining market share in markets including transportation, electronics, healthcare, industrial equipment, consumer appliances, construction, boots, and sporting goods. The main reasons are the plastic's lighter weight and cushioning properties of traditional foams, plus high strength, heat and flame resistance, damping properties, chemical resistance and biological inertness. Core Foam High-performance firing polymers include polyurethanes, polyolefins, silicones, fluoropolymers, benzene-based polymers, and other engineering polymers. Some of these materials have superior mechanical properties, heat resistance and chemical stability. Other materials use molecular chain chemical modification, cross-linking treatment or add special fillers to improve the performance of the material. Core Foam High-performance foams are fired by standard methods, such as chemical blowing agents and physical blowing agents. High-performance foams are competitive with non-foamed plastics, metals, natural or synthetic rubbers. Foam materials can be applied to gaskets, sealing products, heat shields, shock and vibration gaskets, auxiliary equipment and electromagnetic shielding devices for EMI/RFI. In fact, there is no accurate definition of high-performance foam materials, so it is difficult to estimate the market share of its products. After proper high-temperature treatment, it can withstand the high-temperature composite material curing process requirements, which makes the foam widely used in the aviation field. The medium-density foam has good compression creep properties and can be cured in an autoclave at a temperature of 120oC -180oC and a pressure of 0.3-0.5MPa. PMI foam can meet the creep performance requirements of the usual prepreg curing process, and can realize the co-curing of the sandwich structure. PMI foam as an aerospace material is a uniform rigid closed-cell foam with basically the same pore size. Suzhou Shincell New Material Co., Ltd. is a professional Foam Sheet Manufacturers.

A Brand New Fitness/Yoga Mat Production
Let’s start with how A KEEP fitness mat is made in Shincell? Generally, there are 3 steps to obtain a perfectly foamed mat in Shincell. 1. Extrusion-from raw material TPU(thermoplastic polyurethanes) granules with colour masterbatch to solid slab/sheet; 2. CO2 and N2 saturation- saturate the slab/sheet with supercritical CO2 and N2 fluid under certain temperature and pressure; 3. Foaming in the foaming machine with CO2 and N2- then by a quick/sudden depressurization/cooled to obtain a foamed original sheet.  As you can tell from the supercritical foaming process, it is a process purely physical. 1. Using ONLY CO2 and N2 as foaming agent instead of chemical agents 2. The foamed sheets are #non-crosslinked, which means #recyclability.  Compared with traditional chemical foaming, which uses AC agent (azodicarbonamide), the specially added chemical foaming agent. The gas generated by thermal decomposition or chemical reaction between raw material components makes the plastic melt fill with cells. In the process, there will be harmful carcinogens such as formamide, which might remain on the finial product and cause Irreversible damage to people’s health.  Advantages of supercritical foaming: 1.Supercritical foaming produces clean and environmental materials with food safety grade and good compatibility with skin. 2. Compared with chemical foaming ones, supercritical foaming materials have finer cell structure and more stable performance. 3. The supercritical foamed foam has greater impact resistance, better thermal stability, toughness, and good sound insulation LOW CARBON FOOTPRINT An important part of the #circular economy and #sustainable development- Shincell’s training pads(KEEP, Yottoy) are a product of #LOWCARBONFOOTPRINT! In the foaming process of supercritical physical foaming, the gases added are mainly carbon dioxide and nitrogen. The ODP of carbon dioxide = 0, and the GWP (global warming potential) is directly and indirectly relevant with the amount of greenhouse effect gases (mainly carbon dioxide). Alternatives with relatively small GWP should be preferable. The use of carbon dioxide as the foaming agent is completely in line with this principle. The carbon dioxide used by Shincell is only a by-product of other industrial processes- CO2 reuse! In conclusion, training mats are produced in a way that minimizes waste of resources and avoids emission of pollution, uses no or less resource-scarce materials or toxic/hazardous materials, pursues product reusability, improves resource utilisation, poses no health or safety risks to customers and has no or little negative impact on the environment.#Shincell New Materials has created a fully #recyclable #TPU fitness mat, a product made to be remade.

Synthetic Method Of Thermoplastic TPU Material
Thermoplastic polyurethane elastomer (TPU) is a kind of elastomer that can be plasticized by heating and can be dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in national defense, medical treatment, Food and other industries. The outstanding features of polyurethane thermoplastic elastomers are excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and environmental resistance. The hydrolytic stability of type ester is much higher than that of polyester type. The synthesis method of TPU can be divided into two categories according to the presence or absence of solvent: solvent-free bulk polymerization method and solvent-containing solution polymerization method. Bulk polymerization can be divided into one-step method and prepolymer method according to the reaction steps. The one-step method is to simultaneously mix the oligomer diol, diisocyanate and chain extender. The one-step process is simple and easy to operate, but the heat of reaction is difficult to remove and side reactions are likely to occur. Polyester-type thermoplastic polyurethane elastomer was synthesized by one-step method. Firstly, the formula amount of polyester polyol and chain extender, butanediol was weighed in the reactor, and the temperature was raised to 120°C for vacuum dehydration. Quickly add the preheated liquid and stir evenly, pour it into the preheated container, bake it under vacuum at 120°C, then lower the temperature to 100°C to get a light yellow translucent polyurethane product, and then press it on a flat press to form a test piece , the prepared TPU has high mechanical properties and damping properties.

Fireproof, thermal insulation and light-weight material for EV battery protection
Keeping the battery safe and sound has become one of the biggest concerns of new energy vehicles. There are 4 types of new energy vehicles: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV) and vehicles of other new energy sources (high-efficiency energy storage devices, like supercapacitors, flywheels and so on). In 2021, 3.521 million EV were sold in China, a year-on-year increase of 1.6 times, ranking first in the world for seven consecutive years. While with the increasing of sales number, the vehicles’ safety issues are also becoming increasingly prominent. According to the statistics, there were over 3,000 fire incidents caused by EV across the country in 2021. Most of the incidents were caused by the failures of power batteries. EV battery packs are usually composed of multiple single battery modules. Situations like mechanical damage, thermal shock, internal short circuit, long-term and continuously frequent fast-charging in an environment of high temperature, etc. may lead to "thermal runaway" of individual battery module. Then heat spreading to other modules, causing the temperature of the surrounding single cells to rise rapidly to 500 to 1000 °C. Which eventually lead to the catastrophic consequences of the overall combustion and explosion of the battery pack. This is truly a serious potential safety hazards. At present, the fireproof materials for battery packs of new energy vehicles are mainly fireproof felt material, such as heat insulation blankets, mica boards, ultra-fine glass wool, high-silica cotton felts, etc. Although the fireproof blanket can effectively prevent the heat from spreading, control the direction of the fire, and delay the heat diffusion time, the use of the fireproof blankets also bring about weight problem, poor heat dissipation performance, and limitations in the design and construction process. Which hinder the development of lightweight automobiles. Therefore, materials of light weight and excellent flame-retardant are the first choice for the EV battery protection. As to this purpose, #Shincell’s supercritical foamed #MPP and #FR-MPP are used as battery buffer for new energy batteries. It has excellent properties such as lightweight, low thermal conductivity, good cushioning performance, flame-retardant without toxic gas, nonabsorbency, high volume resistivity and Long-term aging resistance. At the moment, we are working with BYD for its demand of light-weight and flame-retardant protective materials.   From #Shincell  Below shows how a #non-crosslinked foam sheet is made by supercritical foaming technology. In the whole process, ONLY CO2 and N2 are used as blowing agent. 1. Raw material extrusion to solid sheet 2. Solid sheet saturation 3.

Introduction To Microcellular Foam Board
Microcellular Polypropylene foam, referred to as MPP, refers to polypropylene porous foam material with a cell size of less than 100 microns (more strictly defined as a cell size of less than 10 microns and a cell density greater than 10 to the 9th power/cm3). Due to the existence of a large number of micron-sized cells inside the material, MPP has excellent shock absorption, cushioning, heat insulation and sound absorption properties, and can be widely used in packaging, vehicles, bags, sports equipment and other fields. It is the traditional EVA, PU, The best substitute for PS foam material, EPE and EPP. Performance and Application Supercritical carbon dioxide technology (supercritical carbon dioxide) is used to prepare MPP. Carbon dioxide gas is introduced into the polypropylene material matrix under high temperature and high pressure, and its nucleation and foaming are induced to form a microcellular foam material containing a large number of micron-scale cells. The foaming process is clean and pollution-free, and the foamed products are hygienic and environmentally friendly. The PP material is not cross-linked during the foaming process, so it can be recycled and reused. Polypropylene (PP) itself is a non-toxic material, and it is a commonly used material for baby feeding bottles and microwaveable lunch boxes. The clean and hygienic MPP is especially suitable for the fields requiring high hygienic level of packaging materials such as medical equipment and food. It can also be used in children's puzzles, toys and other fields with high product health requirements, replacing the commonly used cross-linked PE foam and EVA foam made of AC foaming agent. PP is a semi-crystalline polymer, and its melting point is generally 150~170°C. Compared with PE, PS, and PU foam materials whose temperature resistance is only 70~80°C, MPP can be used at a temperature up to 120°C, so MPP is especially suitable for high-temperature packaging, high-temperature insulation and other fields. MPP integrates reinforcement, heat insulation and noise reduction, and is especially suitable for fields with high requirements for lightweight materials, such as automobiles, rail transit, ships, and fan blades. Lightweight and high-strength MPP thick boards are used as structural foams to replace traditional structural foams such as PVC/PU interpenetrating structural foams, PET structural foams, etc., especially as core materials for sandwich composite materials.

Properties Of PVDF Material
In 1969, researchers discovered that PVDF has a strong piezoelectric effect: the piezoelectric coefficient of the polarized (that is, put in a strong electric field to generate a net dipole moment) film is 6-7pC/N, which is higher than that of the polymers that had been discovered at that time. The value is more than 10 times larger. [3] PVDF has a glass transition temperature (Tg) of approximately −35°C and typically has a crystallinity of 50–60%. To impart piezoelectric properties to a material, the material is usually mechanically stretched along the direction of the molecular chain, and then polarized under tension. PVDF has a variety of solid phases: α phase (TGTG'), β phase (TTTT) and γ phase (TTTGTTTG'). The difference between these phases is whether the molecular chain is cis (T) or trans (G). PVDF will become a ferroelectric polymer after polarization, which has good piezoelectricity and pyroelectricity. These properties make it suitable for the production of sensors and batteries. For example, the sensors of some new thermal imaging cameras use PVDF films. Unlike some other piezoelectric materials, such as PZT, PVDF has a negative d33 value. In a physical sense, this means that PVDF contracts when other materials expand in an electric field, and vice versa.
