High Impact Plastic Sheets (HIPS)
Selangor, Kuala Lumpur (KL), Malaysia, Sungai Buloh
Pure polystyrene is brittle, but hard enough that a fairly high-performance product can be made by giving it some of the properties of a stretchier material, such as polybutadiene rubber.
Polystyrene is a versatile plastic that can be rigid or foamed. It is a low cost member of the plastics family. It also generally recognized as the best styrenic material.
Polybutadiene is added during polymerization it can become chemically bonded to the polystyrene, forming a graft copolymer which helps to incorporate normal polybutadiene into the final mix, resulting in high-impact polystyrene or HIPS, often called "high-impact plastic" in advertisements.
Common applications include use in toys and product casings. HIPS is usually injection molded in production. Autoclaving polystyrene can compress and harden the material.
