The role of MST® China Zinc Oxide In Rubber Processing in rubber:
1. China Zinc Oxide In Rubber Processing can improve the thermal conductivity, wear resistance, tear resistance, tensile strength and other indicators of the product in the rubber tire industry; thus, it helps the tires to dissipate heat and ensure driving safety. Zinc oxide additives also prevent the erosion of rubber by mold organisms or ultraviolet rays.
2. China Zinc Oxide In Rubber Processing functions in rubber products, synthetic rubber, natural rubber, natural latex: as an activator, vulcanization accelerator and reinforcing agent, and has a coloring effect. Promote the vulcanization, activation and reinforcement of rubber, anti-aging, and improve the corrosion resistance, tear resistance, elasticity and elongation of rubber products.
3. China Zinc Oxide In Rubber Processing acts as a colorant and filler in the white latex.
4. The role of China Zinc Oxide In Rubber Processing in chloroprene rubber: as a vulcanizing agent and a compounding agent to increase thermal conductivity.
5. China Zinc Oxide In Rubber Processing is an essential inorganic activator in transparent rubber and food rubber products.
6. China Zinc Oxide In Rubber Processing has an irreplaceable role in transparent or colored rubber products such as carbon black and other traditional active agents.
The high quality and high purity of MST® China Zinc Oxide In Rubber Processing produced by MST ensures that zinc oxide has a more complete vulcanization and activation effect in rubber processing. It is an important additive in the production of rubber products.
