GON Raw Polystyrene Pellets GPPS 525 Plastic Particle Plastic Raw Materials
Polystyrene is a colorless and transparent thermoplastic with a glass transition temperature above 100°C. Therefore, it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes. The usual polystyrene is an amorphous random polymer, with excellent insulation, insulation and transparency, long-term use temperature 0 ~ 70 ℃, but brittle, low temperature cracking.
Polystyrene (PS) is mainly divided into general-purpose polystyrene (GPPS) and high-impact polystyrene (HIPS). After toughening HIPS impact toughness than GPPS increased by 4 times, good dimensional stability.
