Makrolon? PC from Germany Covestro 6555 halogen-free flame retardant V0 resistant to high temperatures for electronic electrical applications

PC is a linear carbonate polyester, in which the carbonate groups in the molecule are alternately arranged with some other groups, which can be aromatic, aliphatic, or both. Bisphenol A PC is the most important industrial product.

PC is an almost colorless glassy amorphous polymer with excellent optical properties. PC high molecular weight resin has high toughness, the impact strength of the cantilever beam notch is 600~900J/m, the thermal deformation temperature of the unfilled grade is about 130°C, and the glass fiber reinforcement can increase this value by 10°C. The bending modulus of PC can reach more than 2400MPa, and the resin can be processed into large rigid products. Below 100°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.

The main performance defects of PC are not high enough hydrolysis stability, sensitive to notch, organic chemical resistance, poor scratch resistance, long-term exposure to ultraviolet light will turn yellow. Like other resins, PC is susceptible to attack by certain organic solvents.

PC material is flame retardant. Resistance to oxidation

Anti-static PC, conductive PC, fibre-added fireproof PC, UV resistant PC, food grade PC, chemical resistant PCThe three major application areas of PC engineering plastics are the glass assembly industry, the automotive industry and the electronics and electrical appliances industry, followed by industrial machinery parts, optical discs, packaging, computers and other office equipment, medical and health care, film, leisure and protective equipment. PC can be used as Windows and doors glass, PC laminate is widely used in banks, embassies, detention centers and public places of protective Windows, for aircraft cabin covers, lighting equipment, industrial security plates and bulletproof glass 

PC is characterized by high transparency, high impact resistance, high hardness, high creep-resistance, excellent dimensional

stability, good resistance to low-temperature and heat, flame retardance, ease to process, and excellent sound insulation.
