It can also be radiation sterilized. When modified by incorporating elastomers, polystyrene homopolymer turns into (high) impact polystyrene or HIPS, which is usually opaque. As a result, a wide ...

High impact polystyrene contains rubber. It is less transparent than GPPS. It is mainly used for products that require high-impact resistance. HIPS has a standard flow but is less glossy than GPPS.

High-impact polystyrene (HIPS) nanocomposites were prepared by melt compounding two grades of organoclays (Cloisite 10A (C10A) and Cloisite 30B (C30B)) in a Haake internal mixer or a corotating ...
