PP

Polypropylene

Is a kind of PP raw material for the substrate processing of profiles, PP plate density is small, easy to weld and process, with superior chemical resistance, heat resistance and impact resistance, non-toxic, tasteless is currently the most in line with environmental requirements of one of the engineering plastics, can reach the food contact material grade. The operating temperature is -20-90°C.
