China Zinc Oxide For Vulcanization Rubber manufacturers

In order to improve the performance of rubber products, a series of processing processes must be carried out on the raw rubber in production. Under certain conditions, the raw rubber in the rubber compound and the vulcanizing agent are chemically reacted, making it cross-linked by linear macromolecules. The macromolecules with three-dimensional network structure make the rubber compound have high strength, high elasticity, high wear resistance, corrosion resistance and other excellent properties. This process is called rubber vulcanization.MST® China Zinc Oxide For Vulcanization Rubber manufacturers is an important vulcanizing agent in the rubber vulcanization process.You can rest assured to buy MST® China Zinc Oxide For Vulcanization Rubber manufacturers from our factory and we will offer you the best after-sale service and timely delivery.

The role of MST® zinc oxide for vulcanization rubber in rubber vulcanization:

1) Zinc oxide for vulcanization rubber is used as an accelerator in the rubber vulcanization process. It is a multifunctional rubber compounding agent, mainly used as a vulcanization activator and reinforcing agent for natural rubber, synthetic rubber and latex.

2) When zinc oxide for vulcanization rubber is used as a vulcanization activator in rubber vulcanization, it is evenly distributed in the rubber compound, has a large contact area with hydrogen sulfide, and has a greater opportunity for interfacial reaction. In addition, the active zinc oxide product has active substances. Promoting catalysis, the conversion rate of zinc oxide to zinc sulfide is high.

3) Zinc oxide for vulcanization rubber is used as a vulcanizing oxidant in rubber vulcanization. Its function is to enhance the activity of the accelerator, reduce the amount of accelerator, and shorten the vulcanization cycle.

4) Zinc oxide for vulcanization rubber can accelerate the vulcanization speed during rubber vulcanization, improve the thermal conductivity of the vulcanized rubber, and make the vulcanization more thorough.

Zinc oxide for vulcanization rubber produced by MST has high purity, strong activity, uniform particle size, and good dispersibility. It has a good effect of accelerating vulcanization, increasing the cross-linking density of vulcanized rubber and making vulcanization more thorough.
