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、**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是一种中等耐磨材料(但比金属好得多)。与尼龙、聚、氯化聚醚、聚四氟乙烯等相比,但优于ABS、聚砜、**玻璃等。通过添加聚四氟乙烯、玻璃纤维等填料,可以提高PC的耐磨性,降低摩擦系数和磨损损失,提高PV值。PC具有良好的耐热性和耐寒性。可在-100~130℃范围内长期使用。具有较高的载荷变形温度(130~140℃),受载荷影响较小。脆性温度在-100℃以下,即使在-180℃也不会像玻璃一样破碎。PC无明显熔点,在220~230℃熔融。由于高分子链的高刚性,其熔融粘度远**其他热塑性塑料
