In the curing process of natural rubber and most types of synthetic rubbers, the chemical reactivity of Zinc oxide is utilized to activate the organic accelerator. Heavy-duty pneumatic tires carry high loadings of Zinc Oxide for heat conductivity as well as reinforcement. Zinc Oxide serves as the accelerator with some types of elastomer and the crosslinking, Zinc Oxide similarly retards devulcanization of many types of rubber compounds operating at elevated temperatures. Zinc Oxide mainly uses in RUBBER, EVA, CERAMICS etc.


Eliminates bridging or caking while facilitating use in any type of packaging, bulk handling or conveying system.
