Transparent Flame-Retardant Polycarbonate PC Plastic Granules for Electronic Product Shells

Polycarbonate are almost colorless amorphous polymers in a glass state, with good optical properties. PC high molecular weight resin has high toughness, with a notch impact strength of 600-900J/m for cantilever beams, and an unfilled grade with a thermal deformation temperature of approximately 130 ° C. Glass fiber reinforcement can increase this value by 10 ° C. The bending modulus of PC can reach over 2400MPa, and the resin can be processed into large rigid products. At temperatures below 100 ° C, the creep rate under load is very low. PC has poor hydrolysis resistance and cannot be used for products that repeatedly undergo high-pressure steam. The main performance defects of PC are insufficient hydrolysis stability, sensitivity to notches, poor resistance to organic chemicals, and poor scratch resistance. Long term exposure to ultraviolet light can cause yellowing. Like other resins, PC is susceptible to erosion by certain organic solvents. PC materials have flame retardancy. Antioxidant properties.
