HIPS stands for High Impact Polystyrene is a graft copolymer that is produced with the mix of polybutadiene and polymers of rubber. These two material cannot be mixed into a copolymer form under normal circumstances. To create this grafted copolymer the polybutadiene is added during the polymerization process. The resulting polymer HIPS is produced with the properties of polystyrene and stretchable rubber. The HIPS grade polymers are used in high performance products where thermal resistance and elasticity are in question. The common application of HIPS is in the form of different casing of gadgets, toys that are manufactured with the injection molding process. You can find numerous producers and suppliers of such HIPS based products at eWorldTrade.com.
