Application
ANTIOXIDANT CA is a high efficient phenolic antioxidant. It used as stabilizer and antioxidant for polymers (PS,PP,PE,PVC,PAN,ABS and fiber plastics). It has low volatility, no pollution，discoloration and it won’t decompose under high temperature process. It can improve the heat resistance and oxygen resistance of the products significantly. Additionally, it can inhibit copper damage and apply in polyolefin cable production.
