(Polystyrene / High-Impact Polystyrene)


Polystyrene (PS), polymerized SM, is one of the most commonly used commodity plastics. According to its composition, PS can be categorized into two types: general purpose polystyrene (GPPS), which is polymerized with 100% SM, and high-impact polystyrene (HIPS), which is a SM and rubber copolymer.



The characteristics of PS include excellent electrical-insulation, low water absorption and high fluidity, and it is widely used in the manufacturing of food containers, toys, plastic cards (IC cards), and 3C products. It is an indispensable material in the emerging information and communications industry.
