Chi Mei Polyrex® PH-55Y Polystyrene Resin
Categories:	Polymer; Thermoplastic; Polystyrene (PS); Polystyrene, Molded, Unreinforced
Material Notes:	For general injection/for injection blowing. Medium Impact. Applications: General injection including injection blowing for food containers, beverage containers, toy casings, piano keyboards and parts. POLYREX® PS resin is a solid polymer formed by heat polymerization of styrene (SM). High Impact Polystyrene (HIPS) composed of SM and butadiene (BD). HIPS is high impact resistant and non-transparent. POLYREX® is suitable for home appliances, food and water contact materials, toys, and construction materials, and especially appliance housings due to its excellent processability.
