Zinc Oxide – Properties and Applications for Industrial Rubbers

Zinc Oxide (ZnO)

Zinc Oxide; represented with the formula ZnO is an inorganic compound, white in color and water-insoluble. Though naturally found, most ZnO used commercially is synthetic. Commonly used in treating skin irritations and in medical ointments but in present times, its usage has transcended to industries like rubber, cosmetics, glass & ceramics, agriculture, and other chemicals to mention a few.
Properties of Zinc Oxide that make it popular for the Rubber Industry

Vulcanization of Rubber

As mentioned above, ZnO is the most effective activator to speed up the rate of rubber vulcanization.

Applications of Zinc Oxide for Rubber Industry

Rubber products represent the largest market for Zinc Oxide. ZnO is a widely used compound in rubber industry due to the excellent properties it shows as an activator for vulcanization of rubber. Vulcanization is a chemical process for converting natural rubber into a more durable material. Therefore, ZnO adds strength to rubber compounds and improves their resistance against heat/ abrasion and helps guard against ultraviolet degradation.

Properties of Zinc Oxide that make it popular for the Rubber Industry Vulcanization of Rubber As mentioned above, ZnO is the most effective activator to speed up the rate of rubber vulcanization. Latex Gelation Zinc Oxide is specifically effective in gelation (solidification by freezing) of the foam. Therefore, it gives enough stability in the gelation of foam when latex foam rubber product is manufactured. Heat Stabilization Zinc oxide has very high stability (resistance) in heat. So, it is largely used for tire manufacturing so that the tires are safe even ...
