PC性能:汽车照明,低粘度,紫外线稳定,容易释放,应用程序,照明灯镜头汽车灯光。
PC的缺口冲击强度(NotchedIzod impact stregth)非常高,并且收缩率很低,-般为0. 1%~0.2%。PC有很好的机械特性,但流动特性较差,因此这种材料的注塑过程较困难。在选用何种品质的PC材料时,要以产品的终期望为基准。如果塑件要求有较高的抗冲击性,那么就使用低流动率的PC材料:反之,可以使用高流动率的PC材料,这样可以优化注塑过程。

PC performance: automotive lighting, low viscosity, UV stabilized, easy release, applications, lamp lenses for automotive lighting. PC Overview: the English name of polycarbonate Plyearbonate PC (hereinafter or referred to as PC) . It is a general term for any macromolecule containing a carbonate structure in a class I chain and any materials made from it. According to the different ester groups in the molecular structure, it can be divided into aliphatic group, aliphatic group, aromatic group and fatty aromatic group. And bisphenol-based polycarbonate as an important, usually molecular weight of 3-100,000. In the absence of special instructions, commonly referred to as polycarbonate bisphenol A polycarbonate and its modified varieties. As one of the five engineering plastics, PC is a kind of non-crystal engineering material, it has excellent impact strength, thermal stability, glossiness, bacteriostatic property, flame retardant property and anti-pollution property. PC has a very high NOTCHEDIZOD impact stregth and a very low shrinkage rate-typically 0.5% . 1% ~ 0.2% . PC has good mechanical properties, but poor flow characteristics, so the injection process of this material is difficult. In the selection of what quality of PC materials, to the end-of-life expectations of the product as a benchmark. If the part requires a high impact resistance, use a PC material with a low flow rate; conversely, use a PC material with a high flow rate, which optimizes the injection process.
PC uses: optical lighting for manufacturing large lampshade, protective glass, optical instruments around the eyepiece tube, etc. . Also can be widely used in aircraft transparent materials. Polycarbonate is an excellent E (120 ° C) class insulating material for electrical and electronic appliances. It is used for manufacturing insulating connectors, coil frames, tube pedestals, insulating sleeves, telephone case and parts, battery case of Miner's lamp, etc. . It can also be used to make parts with high dimensional accuracy, such as compact discs, telephones, computer, 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 tape, etc. . Mechanical equipment for the manufacture of various gears, rack, worm, worm, bearing, Cam, bolt, lever, crankshaft, Ratchet, it can also be used as housing, cover and frame of some mechanical equipment. The medical apparatus can be used as cups, tubes, bottles, dental instruments, medicine containers and surgical instruments for medical purposes, and even as artificial organs such as artificial kidneys and artificial lungs. In other aspects, it is used as hollow rib double wall panel, greenhouse glass, etc. in the textile industry as textile yarn tube, textile machine bush, etc Daily use for baby bottles, tableware, toys, models, LED lamp shell and mobile phone shell
