PS is the abbreviation of "polystyrene" in English, which refers to a thermoplastic polymer synthesized by free radical addition polymerization of styrene monomer.
Polystyrene is an amorphous polymer, and the side group of its macromolecular chain is benzene ring, and the main side group is benzene ring. Its irregular structural forms, such as high transparency, high hardness, high glass transition temperature and brittleness, etc.
Expandable polystyrene is a physical foaming agent with low boiling point, which is soaked in ordinary polystyrene and foamed after heating. It 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 properties of materials, but the products are opaque.
The use of polystyrene
Polystyrene is easy to process and shape, and has the advantages of transparency, cheapness, rigidity, insulation and good printability. It can be widely used in light industry market, daily decoration, lighting indication and packaging.
In electricity, it is a good insulating material and heat insulating material, which can be used to make various instrument shells, lampshades, optical and chemical instrument parts, transparent films, capacitor dielectric layers and so on.
Can be used for powder and emulsion cosmetics. Used in powder cake, it has good compressibility and can improve the adhesion of powder. Giving skin luster and lubricity, it is an advanced filler to replace talcum powder and silicon dioxide.
