Weather Resistant Halogen-free Flame Retardant PC EXL9330

PC is an almost colorless glassy amorphous polymer with excellent optical properties.

PC high molecular weight resin has high toughness, with a cantilever beam notch impact strength of 600-900J/m. The unfilled grade has a thermal deformation temperature of approximately 130 ° C, and 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. Below 100 ° C, the creep rate under load is very low. PC has good hydrolysis resistance, but cannot be used for products that are repeatedly subjected to high-pressure steam.    

The main performance defects of PC are insufficient hydrolysis stability, sensitivity to notches, poor resistance to organic chemicals, poor scratch resistance, and yellowing when exposed to ultraviolet light for a long time. Like other resins, PC is susceptible to being soaked by certain organic solvents.
