Why do refrigerator drawers use PS material and PS characteristics？
The drawer of refrigerator uses the PS material of entrance, it is a kind of engineering plastic, bearing capacity is strong, without juncture, easy to clean.
The drawer of refrigerator is very exquisite, because want to bear low temperature, must be very exquisite on material so, want to assure safety and sanitation already, assure avirulent environmental protection even. General household refrigerator drawers are made of PS, also known as polystyrene, a universal plastic, belonging to the hard glue. PP is a soft adhesive, PPS is engineering plastics, the cost is very high. So the mainstream refrigerator drawer is made of PS, transparent GPPS, referred to as transparent benzene, non-transparent HIPS referred to as modified benzene, refrigerator drawer is basically transparent benzene, and refrigerator inner bladder is modified benzene, the reason why PS is done, because PS has low temperature resistance conditions.
The main characters of PS materials
1, mechanical properties: high strength, fatigue resistance, size stability, creep is also small (there is little change under high temperature conditions);
2, heat aging: enhanced UL temperature index up to 120~140℃ (outdoor long-term aging is also very good);
3, solvent resistance: no stress cracking;
4, water stability: easy to decompose in water (use in high temperature and high humidity environment should be cautious);
5, electrical performance;
6, molding processability: ordinary equipment injection or extrusion. Due to the fast crystallization speed, good fluidity, mold temperature is also lower than other engineering plastics requirements. It takes only a few seconds to process thin-walled parts and 40 to 60 seconds to process large parts.
The application of this material
1, electronic and electrical appliances: connectors, switch parts, household appliances, spare parts, small electric cover or (heat resistance, flame retardant, electrical insulation, molding processing);
2, car outer parts, mainly corner geshan, engine heat hole cover, etc.; Internal parts, mainly endoscope support, wiper bracket and control system valve; And automotive electrical parts, including automotive ignition coil twisted pipe and a variety of electrical connectors;
3, mechanical equipment: video tape recorder belt drive shaft, computer cover, mercury lamp cover, iron cover, baking machine parts and a large number of gear, CAM, button, electronic watch shell, camera parts (heat resistance, flame retardant requirements).
