Polycarbonate (PC for short) is a polymer with carbonate group in the molecular chain, which can be used in the development industry, building materials industry, automobile manufacturing industry, medical equipment, aerospace, packaging field and so on.
One, the development of the industry
PC engineering plastics of the three major applications is the glass assembly industry, automotive industry and electronics, electrical appliances industry, followed by industrial machinery parts, CD-ROMs, packaging, computers and other office equipment, medical and health care, film, leisure and protective equipment.
Two, the building materials industry
Polycarbonate sheet with good light transmission, impact resistance, resistance to ultraviolet radiation and the dimensional stability of its products and good molding and processing performance, so that it than the traditional use of inorganic glass used in the construction industry has a clear advantage in technical performance.
Third, the automobile manufacturing industry
Polycarbonate has a good impact resistance, heat distortion resistance, and good weather resistance, high hardness, so it is suitable for the production of cars and light trucks in a variety of parts and components, which are mainly concentrated in the lighting system, dashboards, heating panels, defrosters and polycarbonate alloy bumper, etc..
Four, medical equipment
Since the polycarbonate products can withstand steam, detergent, heating and high-dose radiation sterilization, and does not occur yellowing and physical properties decline, and therefore is widely used in artificial kidney hemodialysis equipment and other need to be transparent, intuitive conditions under the operation and need to be repeatedly sterilized medical equipment. Such as the production of high-pressure syringes, surgical masks, disposable dental appliances, blood separators and so on.
Expanded Information:
One of the main properties
1, the mechanical properties: high strength, fatigue resistance, dimensional stability, and creep is also small (at high temperatures and also Very little change).
2, heat aging resistance: enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term aging is also very good).
3, solvent resistance: no stress cracking.
4, the stability of water: water at high temperatures is easy to decompose (high temperature and high humidity environment should be used with caution).
Two, the main use
1, optical lighting
Used in the manufacture of large lampshades, protective glass, optical instruments, left and right eyepiece barrels, etc., but also can be widely used for transparent materials on the aircraft.
2, electronic and electrical
Polycarbonate is an excellent E (120 ℃) level of insulating materials, used in the manufacture of insulated connectors, coil frames, tube holders, insulating bushings, telephone shells and parts, battery shells of the lamps and so on.
Can also be used to make parts with high dimensional accuracy, such as optical disks, telephones, electronic computers, video recorders, telephone exchanges, signal relays and other communications equipment. Polycarbonate thin touch is also widely used as capacitors, insulated leather bags, audio tapes, color video tapes and so on.
3, mechanical equipment
Used in the manufacture of a variety of gears, racks, worm gear, worm, bearings, cams, bolts, levers, crankshafts, ratchets, but also for some mechanical equipment shells, covers and frames and other parts.
