PC is a kind of weak polar polymer. Although the electrical insulation of PC is not as good as that of polyolefins, it still has good electrical insulation. Because of its high glass transition temperature and low moisture absorption, it can maintain good electrical properties under a wide range of temperature and humidity conditions. Especially, its dielectric constant and dielectric loss are close to constant in the range of 10 ~ 130 ℃, so it is suitable for manufacturing capacitors. PC polycarbonate has certain chemical resistance. It is resistant to water, organic acid, dilute inorganic acid, oxidant, salt, oil, fatty hydrocarbon and alcohol at room temperature. However, it is eroded by alkali, amine, ketone, ester and aromatic hydrocarbon, and dissolved in trimethyl methane, dichloroethane, cresol and other solvents. Long term immersion in boiling water will also occur hydrolysis. In some chemical reagents, such as carbon tetrachloride, polycarbonate may cause stress cracking
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.
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
The production of PC resin is mainly concentrated in the United States, Western Europe and Japan. The production capacity of these three regions accounts for about 90% of the world's total production capacity. At present, the development of polycarbonate industry in the world presents two major characteristics. One is that production tends to be more centralized and monopolized. The production capacity of Bayer company, Ge chemical company, Dow Chemical Company and 13 bendi company account for about 80% of the world's total production capacity. Among them, Ge electric gas, Bayer, Dow Chemical and Japan's Diren company respectively account for the world's total production capacity in 2000 35%, 31%, 9% and 9% of production capacity. These companies control the world's polycarbonate production technology and dominate the world polycarbonate market. Second, Asia is develo rapidly. In recent years, with the gradual recovery of Asian economy, especially the sustained and rapid development of China's economy, the demand for engineering plastics is becoming stronger and stronger. World famous polycarbonate manufacturers have also come to Asia to invest and build factories.
