a) Products description:
PC is an almost colorless glassy state amorphous polymer with good optical properties. PC high molecular weight resin has high toughness, the Izod notched impact strength is 600~900J/m, the heat deformation temperature of the unfilled grade is about 130 degrees C, the glass fiber can increase the value of the increase of about 10 degrees C. The bending modulus of PC can reach more than 2400MPa, and the resin can be processed into large rigid products. Below 100 C, the creep rate is very low under load. PC hydrolysis resistance is poor, can not be used for repeated high-pressure steam products.
1. PC is made into large bulb shade, protective glass, the right and left eyepiece tube of optical instruments. Also, it is used as the transparent materials in plane.
2. PC is good insulation, made into insulated connector, coil frame, tube socket, insulating sleeve, telephone housing and parts, miner's lamp battery shell. Also, it is used to make fine parts of communication equipment, such as CD-ROM, telephone, computer, video recorder, telephone switches, signal relay. The PC film is used for capacitors, insulation foreskin, recorder, color video tape. etc
3. Machinery and equipment-PC is suitable for gear, rack, worm, bearings, cams, bolts, crank, ratchet, also suitable for machinery and equipment housings, covers and frames.
4. PC can be made into cap, tube, bottle and dental equipment, drug containers and surgical instruments. Even be used as an artificial kidney, artificial lung and other artificial organs.
5. For architectural, PC can be made into Double-wall hollow bars, glass of greenhouse. For textile industry, PC is suitable for making bobbin, textile machine bearing. For daily, PC is good material can be made into tableware, toys and models.
