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 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在工程上具有实用,其中产量,用途广而又早实现工业化生产的则是双酚A型PC,其特点是原料价格低廉,加工性能及制品性能**群,合成双酚A型PC有多种方法,但目前工业生产中采用的主要是法和酯交换法,纯PC树脂是一种无定形、无味、无臭、无毒、透明、呈微、白色或无色的刚而韧的热塑性聚合物;相对分子质量一般在2~7万;燃烧时慢燃,离火后慢熄,火焰呈,燃烧后熔融、起泡,发出的花果臭气味,PC综合性能优良,是重要的工程塑料.
