PC耐老化性和耐燃性 聚碳酸酯的耐热老化性能也相当好，若将其薄膜放置空气中长时间加热，其性能变化很小。聚碳酸酯是可燃的，火焰呈淡、冒黑烟；氧指数仅25%，离开火焰自熄。一般加入卤化物、三氧化二锑、氢氧化镁、磷酸和红磷等改性提高阻燃性。

PC电性能： 聚碳酸酯的分子极性小、玻璃化转变温度高、 吸水性低，因此具有优良的电绝缘性能，接近或相对于向来被认为电绝缘性能优良的PET。聚碳酸酯的电绝缘性与温度、湿度、电场频率和制品厚度密切相关。

PC mechanical properties: polycarbonate has excellent mechanical properties, especially its impact strength and dimensional stability. It is difficult to maintain high mechanical strength in a wide temperature range. Its disadvantages are poor fatigue strength and wear resistance, and easy to produce stress cracking.

PC's aging resistance and flame resistance polycarbonate also have good thermal aging properties. If the film is heated in air for a long time, its performance changes little. Polycarbonate is combustible, the flame is light yellow and black smoke; the oxygen index is only 25%, and it will self extinguish when leaving the flame. Generally, halide, antimony trioxide, magnesium hydroxide, phosphoric acid and red phosphorus are added to improve the flame retardancy.
