Density: 1.18-1.22 g/cm^3 linear expansion rate: 3.8x10^-5 cm/° c heat deflection temperature: 135 ° c low temperature-45 ° c
Polycarbonate colorless, transparent, heat-resistant, impact resistant, flame retardant BI level, temperature in normal use have good mechanical properties. Compared with performance poly methyl methacrylate ester, good impact resistance of polycarbonate, high refractive index, processing performance, and does not need additives with UL94 V-0 flame retardant properties. Poly methyl methacrylate polycarbonate of lower prices, and through the production of large components in bulk polymerization.
Poor wear resistance of polycarbonate. Some polycarbonate for easy wear surfaces need special handling.
