PC, Chinese name is polycarbonate. It is a new type of thermoplastic, transparent 90%, known as transparent metal. It is rigid and tough, with high impact strength, high dimensional stability Wide range of properties and temperature, good electrical insulation properties and heat resistance and non-toxicity, can be injected and extruded.
PC has excellent thermal properties and can be used for a long period of time between -100 °C and 130 °C. The embrittlement temperature is below -100 °C. Although polycarbonate has poor resistance to cracking and chemical resistance, high temperature is easily hydrolyzed, and other resins. Poor compatibility, poor lubricity, but can be modified by adding other resins or inorganic fillers to obtain very good performance.
Polycarbonate application range:
Optical lighting: used to manufacture large lampshades, protective glass, left and right eyepieces of optical instruments, etc., can also be widely used in transparent materials on aircraft.
Electronics: Polycarbonate is an excellent E (120 ° C) grade insulating material for the manufacture of insulated connectors, coil frames, headers, bushings, telephone housings and parts, battery cases for miner's lamps, etc. Also available For the production of high-precision parts, such as optical discs, telephones, computers, video recorders, telephone switches, signal relays and other communications equipment. Polycarbonate thin touch is also widely used as capacitors, insulation bags, tapes, color Video tape, etc.
Mechanical equipment: Used in the manufacture of various gears, racks, worm gears, worms, bearings, cams, bolts, levers, crankshafts, ratchets, as well as mechanical parts, covers and frames.
Medical equipment: Cups, cans, bottles and dental instruments for medical use, pharmaceutical containers and surgical instruments, and even artificial organs such as artificial kidneys and artificial lungs.
Other aspects: The building is used as double siding for hollow ribs, greenhouse glass, etc.; used as textile tube in textile industry, textile machine bearing bush; etc.; used as bottle, tableware, toys and models for daily use.
Polycarbonate (PC) advantages:
1 high strength and modulus of elasticity, high impact strength, wide temperature range
2 high transparency, what color you want to dye
3 heat resistance high. H.D.T. high
4 tasteless and odorless, harmless to the human body, in line with health and safety, food grade
5 low molding shrinkage, good dimensional stability, easy processing
6 excellent electrical characteristics, high flame retardant
7 UV resistance, good weather resistance
8 good fatigue resistance, good toughness
Polycarbonate (PC) disadvantages:
1The design of the molded product is not easy to generate internal stress problems (how to eliminate the internal stress of PC plastic products)
2 When processing, the injection molding machine is required to be high, and the processing temperature is about 310 degrees.
