Features of Three Layers HIPS Volume Conductive Blister Sheet Roll For LED Packaging The composition of high impact polystyrene is polystyrene and rubber. There are two preparation methods, namely mechanical blending method and graft polymer. The mechanical blending method is to mix the polystyrene and rubber in proportion and blend them in an extruder, a kneader or a double upset press. The amount of rubber is generally 10% to 20%. Due to the limited compatibility of the two polymers, the rubber phase is not uniformly dispersed in the polystyrene phase, so the toughening effect is not significant, and the toughness of the blend will not be greatly improved, with only some improvements.
HIPS is a white or yellow opaque thermoplastic resin. In addition to excellent impact properties, HIPS also has most of the advantages of polystyrene, such as good dimensional stability, good rigidity, easy processing, high gloss, easy to color, etc., but HIPS tensile strength, light stability, oxygen permeability Worse. HIPS is suitable for manufacturing various electrical parts, equipment covers, instrument parts, refrigerator linings, containers, food packaging and disposable appliances.
