2. Product usage:

Industrial production of zinc oxide have 50% flow rubber industry. Zinc oxide and stearic acid as rubber vulcanization of reactants, is an important raw material of rubber manufacturing.

Zinc oxide and stearic acid mixture of enhanced rubber sclerosis. Zinc is the important additive car tyres. Besides, zinc sulfide can greatly enhance the heat transfer performance of rubber tyres, which helps the radiator, ensure safety. Zinc oxide additives also prevented mildew biological or ultraviolet for rubber erosion.
