苯乙烯的三个最重要等级是：

GPPS：通用聚苯乙烯，也称为透明聚苯乙烯，是一种完全透明、坚硬且相当脆的低成本热塑性塑料，由苯乙烯单体制成。GPPS是一种固体产品，以2-5毫米颗粒的形式制造

HIPS：高抗冲聚苯乙烯通常含有5%至10%的橡胶（丁二烯），用于要求高（er）抗冲性的零件。HIPS是一种具有聚苯乙烯侧臂的接枝共聚物。当一些自由基与聚丁二烯的双键发生反应时，就会发生接枝反应

EPS：可膨胀聚苯乙烯由含有发泡剂的微丸或微珠组成。发泡聚苯乙烯具有隔热性、高抗冲击性和良好的加工性能

Factory Manufacturer Regrind GPPS Granules Heat Resistance HIPS GPPS Material

The three most important grades of styrene are:

GPPS: General purpose polystyrene, also known as crystal-clear polystyrene, is a fully transparent, rigidand rather brittle low cost thermoplastic made from styrene monomer. GPPS is a solid product manufactured in the form of 2-5 mm pellets.

HIPS: High impact polystyrene contains usually 5 to 10% rubber (butadiene) and is used for parts which require high(er) impact resistance. HIPS is a graft copolymer having polystyrene sidearms. The grafting occurs when some of the radicals react with the double bonds of the polybutadiene.

EPS: Expandable polystyrene consists of micro-pellets or beads containing a blowing agent . The expanded or foamed polystyrene is thermally insulating, has high impact resistance and good processability.
