PS is the abbreviation of polystyrene in English, which refers to a thermoplastic polymer synthesized by free radical addition reaction of styrene monomer. Polystyrene is an amorphous polymer with a benzene ring as the main side group of its macromolecular chain. Its irregular structural form includes high transparency, high hardness, high glass transition temperature, and brittleness. Expandable polystyrene is a kind of low boiling point physical foaming agent soaked in general polystyrene, heated and foamed, which is specially used to make foam products. Polystyrene with good impact resistance is a polymer composed of butadiene and butadiene. Its dispersed phase can improve the impact performance of the material, but the product is not transparent. The intermediate polystyrene is a new type of polymer material with good properties, and it is a new type of polymer material with excellent properties. Polystyrene is a colorless, transparent, and colorable material, with a relative densi…
