Polystyrene (PS) granules: is composed of styrenemonomer (SM) polymerization, can be synthesized by a variety of synthetic methods, the current industry mainly by bulk polymerization and suspension polymerization.
Polystyrene(PS) is a thermoplastic non-crystalline resin, mainly divided into General Purpose polystyrene (GPPS), High Impact polystyrene (HIPS) and Expandable Polystyrene  (EPS) .
1. Polystyrene foam (Expanded Polystyrene referred to as EPS) is a light-weight polymer. It is the use of polystyrene resin into the blowing agent, while heating to soften, produce gas,forming a hard closed-cell structure foam Plastic.

2.Impact resistant polystyrene (HIPS) is an impact resistant polystyrene product produced by adding polybutyl rubber particles to polystyrene.

Application:

1. High Impact Polystyrene( HIPS)
HIPS can be used to produce the shells of electrical household appliances, toys, automobile parts, daily necessities, etc. HIPS has excellent impact resistan ce, rigidity,electrical insulating property, corrosion res istance and dyeability.

2. General purpose polystyrene (GPPS)         Lamps, telecommunications accessories, electric frequency capacitors film, high-frequency insulation materials, television sets and other containers, waveguide, chemical containers.ade is mainly used for making rotomolded products, large-sized outdoor toys, storage tanks, roadblocks, etc.        

3. Expandable polystyrene (EPS)            steel (board) grid composite light panels,             wall outside the paste board, roof insulation boards and geothermal panels, it is more widely Used in the field of housing construction, for insulation, heat insulation, waterproof and moisture-proof materials on the ground.
