PC is an almost colorless glassy amorphous polymer with good optical properties. PC high molecular weight resin has high toughness, the notched impact strength of cantilever beam is 600~900J/m, and the thermal deformation temperature of unfilled brand is about130 C, which can be increased by glass fiber reinforcement.
The bending modulus of PC can reach more than 2400MPa, and the resin can be processed into large rigid products. When it is lower than100 C, the creep rate under load is very low. PC has poor hydrolysis resistance and cannot be used for products repeatedly subjected to high-pressure steam.
Extended data:
Polycarbonate has good impact resistance, thermal deformation resistance, weather resistance and high hardness, and is suitable for producing various parts of cars and light trucks, mainly focusing on lighting systems, dashboards, heating plates, defrosting devices and bumpers made of polycarbonate alloy.
The three major application fields of PC engineering plastics are glass assembly industry, automobile industry and electronic appliance industry, followed by industrial machinery parts, compact discs, packaging, computers and other office equipment, medical care, films, leisure and protective articles.
PC can be used as door and window glass, and PC laminates are widely used as protective windows in banks, embassies, detention centers and public places, as well as aircraft cabin covers, lighting equipment, industrial safety baffles and bulletproof glass.
