huayun plastic componentspolycarbonate is a strong thermoplastic resin, its name comes fromits internal co3 group. it can be synthesized from bisphenol a andcarbon oxychloride cocl2. the more commonly used method is the melttransesterification of bisphenol a and diphenyl carbonate throughtransesterification and polycondensation. the properties ofpolycarbonate pc is a polycarbonate of carbonic acid. carbonic aciditself is not stable, but its derivatives such as phosgene, urea,carbonate, carbonic acid ester are stable. polycarbonates can beclassified into aliphatic and aromatic groups according to theiralcohol structure. aliphatic polycarbonate. such as poly (ethylenecarbonate) , poly (trimethylene carbonate) and their copolymers,which have low melting point and glass transition temperature, poorstrength and can not be used as structural materials, but takeadvantage of their biocompatibility and biodegradable propertiesand can be used as drug slow release carriers, surgical suture,bone support materials and other applications. polycarbonate isresistant to weak acid, weak alkali and neutral oil. polycarbonateis not resistant to ultraviolet light and strong alkali. pc is alinear carbonated polyester in which the carbonated groupsalternate with other groups, which may be aromatic, aliphatic orboth. bisphenol a type pc is the most important industrial product.pc is an amorphous polymer of almost colorless glassy state withgood optical properties. pc high molecular weight resin has hightoughness, the notched impact strength of cantilever beam is 600 ~900j / m, the thermal deformation temperature of unfilled grade isabout 130 °c, the value can be increased by 10 °c after glass fiberreinforced. the bending modulus of pc can reach over 2400mpa, andthe resin can be processed into large rigid products. the creeprate under load is very low below 100 °c. pc poor hydrolysisresistance, can not be used for repeated exposure to high-pressuresteam products.
