 PC plastic materials properties and uses 

 Physical properties 
 The PC is an amorphous engineering materials, with a particularly good impact strength, thermal stability, gloss, and inhibit bacterial properties, flame retardant properties, as well as anti-pollution. PC gap, the Iraqi estimate Germany is very high impact strength (otched Izod impact stregth) and the contraction rate is very low, generally 0.1% to 0.2%. 
 Chemical properties 
 PC has good mechanical properties, but poor flow characteristics, the injection molding process of this material is more difficult. The choice of what kind of quality PC material, to the ultimate expectations of the Product. Requirements of plastic parts have a higher impact resistance, and then use a low turnover rate of the PC material; the contrary, you can use the high turnover rate of the PC material, so you can optimize the injection molding process. 
 PC plastic materials it is a new type of thermoplastic, transparent up to 90%, known as the transparent metal. It is rigid and resilient, with high impact strength, a high degree of dimensional stability and a wide range of working temperature, good electrical insulating properties and heat resistance and non-toxic, can be delivered by injection, extrusion molding. PC plastic thermal performance and long-term use, can be between -100 ℃ -130 ℃, the brittle transition temperature below -100 ℃. 
 Although the polycarbonate are resistant to cracking and poor chemical resistance, high temperature hydrolysis easy compatibility with other resins is poor, poor lubricating properties, however, can be modified by joining the other resins or inorganic fillers, resulting in excellent performance. 
 Range of applications 
 Optical illumination: used in the manufacture of large-scale shade, protective glass, optical instruments left and right eyepiece can be widely used in the transparent material on the plane. 
 Electronics: Polycarbonate is excellent E (120 ° C) grade insulation material used in the manufacture of insulated connectors, coil frame, tube socket, insulated casing, telephone shell and parts, miner's lamp battery shell. Also be used for the production size with high precision parts, such as CD-ROM, telephone, computer, video recorder, telephone switches, signal relays and other communications equipment. Polycarbonate thin touch has also been widely used as a capacitor, insulated bags, tapes, color video tape. 
 Machinery and equipment: used to manufacture all kinds of gear, rack, worm, worm, bearings, cams, bolts, levers, crank, ratchet, also available as shields some mechanical parts, cover and framework parts. 
 Medical equipment: can be used for medical purposes cup, tube, bottle, and dental equipment, drug product containers and surgical instruments, and even can be used as an artificial kidney, artificial lung artificial organs. 
 Other aspects: architecture as a hollow tendon, siding, greenhouses, glass, etc.; in the textile industry as a textile yarn, textile machine bearing; daily aspects such as baby bottles, tableware, toys and models.
