聚碳酸酯无色透明,耐热,抗冲击,阻燃BI级,在普通使用温度内都有良好的机械性能 。同性能接近聚甲基丙烯酸甲酯 相比,聚碳酸酯的耐冲击性能好,折射率高,加工性能好,不需要添加剂就具有UL94V-2级阻燃性能。但是聚甲基丙烯酸甲酯相对聚碳酸酯价格较低,并可通过本体聚合 的方法生产大型的器件。
材料的耐磨性是相对的,把ABS材料与PC材料做比较的话,那就是PC材料耐磨性比较好。但是相对于大部分的塑胶材料来看,聚碳酸酯的耐磨性是比较差的,处于中下水平,所以一些用于易磨损用途的聚碳酸酯器件需要对表面进行特殊处理。

Polycarbonate is colorless andtransparent, heat-resistant, impact resistant, flame retardant BIgrade, and has good mechanical properties within normal usagetemperatures. Compared to polymethyl methacrylate, polycarbonatehas good impact resistance, high refractive index, goodprocessability, and UL94 V-2 flame retardancy without the need foradditives. However, compared to polycarbonate, polymethylmethacrylate has a lower price and can be used to produce largedevices through bulk polymerization.
The wear resistance ofmaterials is relative. When comparing ABS material with PCmaterial, it is that PC material has better wear resistance.However, compared to most plastic materials, the wear resistance ofpolycarbonate is relatively poor, at the lower middle level.Therefore, some polycarbonate devices used for wear prone purposesrequire special surface treatment.
