HIPS is a modified material of PS, which contains 5-15% rubber component in the molecule. Its toughness is about four times higher
than PS, and its impact strength is greatly improved (high impact polystyrene). There are flame retardant grade, stress cracking
resistance grade, high gloss grade, extremely high impact strength grade, glass fiber reinforcement grade and low residual
volatilization grade.

Other important properties of standard HIPS: bending strength 13.8 ~ 55.1MPa; Tensile strength 13.8 --
41.4MPa; Elongation at break is 15-75%; Density 1.035 -- 1.04 g/ml; It has PS has the advantages of forming processing and strong
coloring force. HIPS products are opaque. HIPS low water absorption, processing does not need to dry in advance.

The main application areas are packaging and disposables, instrumentation, household appliances, toys and entertainment, and the
construction industry. Flame retardant grade (UL V-0 and UL 5-V), impact resistant polystyrene has been produced and widely used
in television cases, commercial machinery and electrical products
