يشير البوليسترين (Polystyrene، والمختصر PS) إلى بوليمر تم تصنيعه من مونومر ستايرين من خلال تفاعل بلمرة الإضافة الجذرية، والصيغة الكيميائية هي (C8H8)n. وهو عبارة عن لدن حراري عديم اللون وشفاف مع درجة حرارة انتقال زجاجية أعلى من 100 درجة مئوية، لذلك غالبًا ما يتم استخدامه لصنع العديد من الحاويات التي يمكن التخلص منها والتي تحتاج إلى تحمل درجة حرارة الماء المغلي، وصناديق الغداء الرغوية التي يمكن التخلص منها.
Polystyrene (PS) includes ordinary polystyrene, expanded polystyrene (EPS), high impact polystyrene (HIPS) and syndiotactic polystyrene (SPS). Ordinary polystyrene resin is non-toxic, odorless, colorless transparent particles, glass-like brittle material, its products have extremely high transparency, light transmittance can reach more than 90%, good electrical insulation performance, easy to color, and process Good fluidity, good rigidity and good chemical resistance. The disadvantages of ordinary polystyrene are brittleness, low impact strength, stress cracking, poor heat resistance, and boiling water resistance.
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.
