Polystyrene homopolymer, known as “crystal" polystyrene in the trade, is an amorphous, colorless, and transparent commodity thermoplastic. It is rigid, brittle, relatively hard and has excellent gamma radiation resistance, good electrical properties but has poor chemical and UV resistance. It can also be radiation sterilized. WebMay 26, 2024 · HIPS is a modified form of polystyrene: Polystyrene (PS) plastic is a naturally transparent thermoplastic material that is available in several forms. The most basic form of PS is general purpose PS (GPPS), also known as crystal PS. GPPS is a result of styrene monomer polymerization and it is a transparent product. happy\\u0027s wine
