The surface of M-PEBA foam board is hard and smooth, with good transparency, strong tinting strength and bright color; the texture is brittle, the impact strength is low, easy to scratch and break; when knocked, the sound is crisp, and it is easy to break when it is bent; relatively The density is greater than one, and it sinks slightly in water.
The structural formula of M-PEBA is a linear structure, but there are huge phenyl groups with continuous intervals on the carbon atoms of the molecular chain, which determines the special properties of polystyrene.
The texture is rigid and the impact strength is low; the random configuration of polystyrene has good gloss, high light transmittance and good colorability. The softening temperature is 80 degrees Celsius. Below 80 degrees Celsius, it is a solid as hard as glass. When it is above 80 degrees Celsius, it becomes a softer object. It has properties similar to rubber. It should be avoided to use at high temperatures.
Good forming performance, within the range of use temperature, the finished product has small shrinkage and deformation, stable size; good water resistance, long-term storage in sunlight will gradually turn yellow, devitrify and crack.
In contact with oils and insect repellants, cracking, discoloration and sticky melting are often seen, and they are prone to aging and yellowing under the action of light, oxygen and heat. It is easily soluble in chloroform, dichloromethane, toluene, butyl acetate and other organic solvents. Avoid contact with the above solvents during storage.
