Polycarbonate (PC) has good mechanical properties and good creep resistance, which is better than that of phthalamide and paraformaldehyde. Especially, PC modified by glass fiber has better creep resistance, so it can bear higher load at higher temperature and ensure dimensional stability. The main shortcomings of polycarbonate mechanical properties are easy to produce stress cracking, poor fatigue resistance, high notch sensitivity, no wear resistance and so on. PC has good high and low temperature resistance, good heat resistance at 120 ℃, and hot deformation temperature of 130 ~ 140 ℃. At the same time, it has good cold resistance, brittleness temperature is - 100 ℃, long-term service temperature is - 70 ~ 120 ℃. Moreover, its thermal conductivity and specific heat capacity are not high, its linear expansion coefficient is small, its flame retardancy is good, and it has self extinguishing property. As a weak polar polymer, PC has better electrical insulation although its electrical insulation is not as good as that of polyolefins. Because of its high glass transition temperature and low hygroscopicity, it can maintain good electrical properties under wide temperature and humidity conditions

PC属中等耐磨材料( 但比金属还是要好很多)。比尼龙、聚、氯化聚醚及PTFE差,但比ABS、聚砜、有机玻璃等好。在PC中加入某些填料可改善耐磨性,例如加入PTFE、玻纤等可降低摩擦系数和磨损量,提高PV值。PC的耐热性和耐寒性都很好,长期使用温度的范围较宽,可在-100~130℃范围使用,其负荷变形温度高(130~140℃),且受负荷影响小;脆化温度在-100℃以下,甚至在-180℃的低温下,也不会象玻璃那样破碎。PC没有明显的熔点,在220~230℃呈熔融状态。由于大分子链刚性大,其熔融粘度比其它热塑性塑料高得多.
PC is a kind of polymer with carbonate group in the main chain, which is called polycarbonate. According to the structure of acetic acid group, PC can be divided into aliphatic, aromatic, aliphatic aromatic and so on. At present, the basic structure of commercial polycarbonate vinegar is aromatic. As a kind of amorphous thermoplastic resin with excellent comprehensive properties, it has excellent electrical insulation, extensibility, dimensional stability and chemical corrosion resistance, Polycarbonate vinegar is a kind of general engineering plastics with fast growth rate. At present, the industrial plant of polycarbonate vinegar basically adopts the process of interfacial polycondensation. The main process is to prepare bisphenol sodium salt from bisphenol and caustic soda solution, add human , and then send it into the reactor, After the reaction, the reaction liquid is sent to the polycondensation reactor, and the solution of caustic soda is added to carry out polycondensation reaction
