According to its different production process, zinc oxide can be divided into indirect zinc oxide ,because it originated in France, it is also called French process zinc oxide, and direct zinc oxide is also called American process zinc oxide and active zinc oxide.
As a Rubber Chemical Suppliers , Rubber grade zinc oxide is the most important inorganic active agent in the rubber industry. The addition of rubber grade zinc oxide can not only speed up the vulcanization rate, but also increase the degree of crosslinking. It has an activating effect on thiazoles, sulfenamides, guanidines and thiuram accelerators.
Because it is a Rubber Chemical Suppliers, rubber grade zinc oxide is widely used in many rubber products, especially transparent rubber products and products that come in contact with food. 50% of industrially produced zinc oxide flows to the rubber industry as a Rubber Chemical Supplierss.
Zinc oxide and stearic acid are important reactants for rubber vulcanization and are one of the raw materials for rubber manufacturing.
The mixture of rubber grade zinc oxide and stearic acid strengthens the hardness of the rubber. As a Rubber Chemical Suppliers, zinc oxide is also an important additive for automobile tires.
In addition to vulcanization, zinc oxide can greatly improve the thermal conductivity of rubber, thereby helping tires to dissipate heat and ensuring driving safety. Zinc oxide additives also prevent the erosion of rubber by mold organisms or ultraviolet rays.
About 50% of the zinc oxide produced by MST is used as MST® rubber chemical raw materials to supply major tire manufacturers. The major well-known brands currently cooperated with are as follows
MST plant, warehouse, lab, office building and material
