HIPS Plastic Sheet Roll For Thermoforming Machine

Polystyrene (Polystyrene, abbreviated PS) refers to a polymer synthesized from styrene monomer through radical addition polymerization reaction, the chemical formula is (C8H8)n. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100°C, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, and disposable foam lunch boxes.

Polistiren (PS) mencakup polistiren biasa, polistiren yang diperluas (EPS), polistiren berdampak tinggi (HIPS), dan polistiren sindiotaktik (SPS). Resin polistiren biasa adalah partikel transparan tidak beracun, tidak berbau, tidak berwarna, bahan rapuh seperti kaca, produknya memiliki transparansi yang sangat tinggi, transmisi cahaya dapat mencapai lebih dari 90%, kinerja insulasi listrik yang baik, mudah diwarnai, dan proses Fluiditas yang baik, kekakuan yang baik, dan ketahanan kimia yang baik. Kerugian dari polistiren biasa adalah kerapuhan, kekuatan benturan yang rendah, retak tegangan, ketahanan panas yang buruk, dan ketahanan terhadap air mendidih.
Impact resistant polystyrene (HIPS) is an impact-resistant polystyrene product produced by adding polybutyl rubber particles to polystyrene. This polystyrene product will add micron-sized rubber particles and connect the polystyrene and rubber particles together by grafting. When subjected to an impact, the tip stress of the crack propagation will be released by the relatively soft rubber particles. Therefore, the propagation of cracks is hindered and the impact resistance is improved.
