Polycarbonate (PC/bullet-proof glass glue)
1. Excellent electrical insulation, extensibility, dimensional stability and chemical resistance;
2. Higher strength, heat resistance and cold resistance;
3. Self-extinguishing, flame-retardant, non-toxic and colorable.
Disadvantages: 1. Poor solvent resistance; 2. Stress cracking; 3. Prone to hydrolysis when immersed in boiling water for a long time; 4. Poor fatigue strength.
Automobile manufacturing industry: Polycarbonate has good impact resistance, thermal distortion resistance, good weather resistance and high hardness, so it is suitable for the production of various parts of cars and light trucks. It is mainly concentrated in lighting systems, instrument panels, Heating plate, defroster, bumper made of polycarbonate alloy, etc.
Optical lighting: used to manufacture large-scale lampshades, protective glasses, left and right eyepiece tubes of optical instruments, etc., and can also be widely used in transparent materials on airplanes.
Electronic appliances: Polycarbonate is an excellent E (120°C) grade insulating material, used to manufacture insulating connectors, coil frames, tube sockets, insulating sleeves, telephone shells and parts, and battery shells for miner’s lamps. It can also be used to make parts with high dimensional accuracy, such as optical discs, telephones, electronic computers, video recorders, telephone switches, signal relays and other communication equipment. Polycarbonate thin film is also widely used as capacitors, insulating bags, audio tapes, color video tapes, etc.
Mechanical equipment: used to manufacture various gears, racks, worm gears, worms, bearings, cams, bolts, levers, crankshafts, ratchets, and some mechanical equipment housings, covers, frames and other parts.
Medical equipment: cups, tubes, bottles, dental equipment, medicine containers and surgical equipment that can be used for medical purposes, and even artificial organs such as artificial kidneys and artificial lungs.
Other aspects: used in construction as hollow rib double-wall panels, greenhouse glass, etc.; in the textile industry, used as textile bobbins, textile machine bearings, etc.; in daily use as milk bottles, tableware, toys, models, LED lamp housings and mobile phone housings, etc. .
