Introduction for PS

The PS resin is divided into GPPS (General Purpose Polystyrene) and HIPS (High Impact Polystyrene).
GPPS is a thermoplastic of excellent transparency, and is a general-purpose resin in wide use owing to its inexpensive cost, excellent process ability and mechanical characteristics. HIPS generally has a rubber content of 5~15%, and is an opaque resin that is applied to products calling for impact resistance.
