Polycarbonate (PC) is a colorless, transparent, glassy amorphous polymer with excellent optical properties. PC high molecular
resin has high toughness, cantilever beam notched impact strength is 600~900J/m. The unfilled grade has a heat distortion
temperature of about 130 °C, which can be increased by 10 °C after it is reinforced with glass fiber. The flexural modulus of PC
can reach more than 2400 MPa, so it can be processed into a large rigid product. Below 100 ° C, the creep rate under load is very
low. PC is poor in hydrolysis resistance and cannot be used to repeatedly process articles subjected to high pressure steam.
