Product Description
PC Series/Polycarbonate
PC is polycarbonate, it is a class of molecular chain containing carbonate structure of polymer compounds and it as a substrate for the production of a variety of materials in general.
1, with ultra-high impact strength, in a wide range of temperatures can still maintain high mechanical strength.
2, outstanding creep resistance, due to water absorption caused by the size and cold flow deformation are very small, which is a sign of excellent dimensional stability.
3, heat resistance, its decomposition temperature above 300 ° C, long-term working temperature can be as high as 120 ° C; also has good cold resistance, embrittlement temperature as low as -100 ° C; its long-term use of the temperature range is -60 ° C ~ 120 ° C.
4, polycarbonate molecular polarity is small, high glass transition temperature, low water absorption, so it has excellent electrical insulation properties.
5, has good aging resistance and flame retardant and permeability, so it has many uses in optoelectronics.
