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.
