Polystyrene refers to a thermoplastic polymer synthesized from styrene monomer through free radical addition polymerization. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100°C, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes. Polystyrene plastic is also widely used in optical instruments, chemical industry and daily necessities to make tea trays, sugar bowls, soap boxes, cigarette cases, student rulers, combs, etc. Due to its certain air permeability, when made into film products, it can also be used as a good food packaging material. Polystyrene (PS) includes ordinary polystyrene, expanded polystyrene (EPS), high impact polystyrene (HIPS) and syndiotactic polystyrene (SPS). Expandable polystyrene is a kind of physical foaming agent with low boiling point soaked in general polystyrene, which is foamed after heating, and is specially used to make foam products. Polystyrene with better crash resistance is a polymer composed of butadiene and butadiene. Its dispersed phase can improve the impact performance of the material, but the product is opaque. The syndiotactic polystyrene is a new type of polymer material with good properties, and it is a new type of polymer material with excellent properties.
PS high transparency polystyrene and rigidity for household appliances daily necessities.
