The Important Role Of Zinc Oxide In Rubber

Rubber grade Zinc oxide (ZnO) is the main inorganic active agent in the rubber industry. Since 1912, Rubber grade zinc oxide is still the best active agent in the rubber vulcanization system, and it is also an irreplaceable active agent. It forms a vulcanization system together with stearic acid, sulfur, and accelerator to accelerate the vulcanization speed and increase the crosslink density.

The Role Of Zinc Oxide In Rubber Products

1. Rubber grade zinc oxide is a good reinforcing agent for rubber industy, It can improve the rubber’s  corrosion resistance, tear resistance, elasticity and elongation.

2.  The accelerator used in the rubber vulcanization process is a multi-functional rubber compounding agent, mainly used as a vulcanization active agent and reinforcing agent for natural rubber, synthetic rubber, latex.

3.  When used as a vulcanization activator, it is evenly distributed in the rubber compound and has a large contact area with hydrogen sulfide, and there is a greater opportunity for interfacial reaction. In addition, this active zinc oxide product has the catalytic effect of active substances to make zinc oxide The conversion rate to zinc sulfide is high.

4. As a vulcanizing oxidant, its role is to enhance the activity of the accelerator, reduce the amount of accelerator, and shorten the vulcanization cycle.

5. It can speed up the vulcanization speed, improve the thermal conductivity of the vulcanized rubber, and make the vulcanization more thorough.

6. In the rubber industry, especially in the production of transparent rubber products, activated zinc oxide is an excellent vulcanization activator.

 

MST chemical coating grade zinc oxide powder is made by indirect method with high purity and low impurities. It can meet all the requirement of coating, And keep customers' product quality stable.
