Polystyrene PS sheet refers to a polymer synthesized by radical addition polymerization of styrene monomer, the English name is Polystyrene, and the Japanese name is ポリスチロール. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100 degrees Celsius, so it is often used to make a variety of disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.

Polystyrene structure: a type of CH-CHZ-}nC6HS Density: 1050kg/m3 Conductivity: (a) 1016S.l''m thermal conductivity: 0.08 Young's modulus: (E) 3000-3600MPa tensile strength :(at)46 stone 0MPa elongation length: 3%% Charpy impact test: 2-5kjjm&suPZ; glass transition temperature: 80-IO0oC thermal expansion coefficient: (a) 8* still, K heat capacity: (c) 1.3kJ/ (k crisp) water absorption rate: (ASTM) 0.0 at 0.1 degradation: 280oC meaning polystyrene refers to a polymer synthesized by free radical addition polymerization of styrene monomer, English classification polystyrene (Ps) including ordinary polyphenylene Ethylene, expanded polystyrene (EPS), high impact polystyrene (HIPS) and syndiotactic polystyrene (SPS). Ordinary polystyrene resin is non-toxic, odorless, colorless transparent particles, like glass brittle material, its products have extremely high transparency, light transmittance can reach more than 90%, PS sheet electrical insulation performance is good, easy Coloring, good processing fluidity, good rigidity and good chemical resistance. The disadvantages of ordinary polystyrene are that it is brittle, the impact strength is low, stress cracking is easy, heat resistance is poor, and boiling water is not resistant. Attributes Ordinary polystyrene resin is an amorphous polymer, the side group of the PS sheet molecular chain is a benzene ring, and the random arrangement of the large volume side groups of the benzene ring determines the physical and chemical properties of the polystyrene, such as high transparency. . Stiff stiffness. High glass transition temperature, brittleness and the like. Expandable polystyrene is a kind of physical foaming agent which is impregnated with ordinary boiling point in ordinary polystyrene. It is heated and foamed during processing, and is specially used as a foam plastic product. High impact polystyrene is a copolymer of styrene and butadiene, butadiene is a dispersed phase, which improves the impact strength of the material, but the product is opaque. Syndiotactic polystyrene is a syndiotactic structure, which is produced by metallocene catalysts. It has developed a new variety of polystyrene with good performance and belongs to engineering plastics.
