In the field of rubber products, what are the functions of indirectly produced zinc oxide? In today's industrial production, at least half of the indirectly produced zinc oxide goes to the rubber industry. As an important reactant in rubber vulcanization, indirectly produced zinc oxide and stearic acid are among the raw materials for rubber production. The mixture of zinc oxide and stearic acid can enhance the hardness of rubber. Zinc oxide is also an important additive in tires.

　　In the field of rubber products, what are the functions of indirect zinc oxide? In today's industrial production, at least half of indirect zinc oxide flows into the rubber industry. As an important reactant in rubber vulcanization, indirect zinc oxide and stearic acid are among the raw materials for rubber production. The mixture of zinc oxide and stearic acid can enhance the hardness of rubber. Zinc oxide is also an important additive for tires. In addition to the vulcanization effect, zinc oxide can also significantly improve the thermal conductivity of rubber, thereby helping tires dissipate heat. Indirect zinc oxide additives can also prevent mildew and ultraviolet erosion of rubber.


Zinc oxide


　　The role of indirect zinc oxide in the rubber tire industry: improving the thermal conductivity, wear resistance, tear resistance, tensile strength and other properties of the product, while saving about 30% of zinc oxide.

　　The role of indirect zinc oxide on rubber products:

　　Active zinc oxide is mainly used as a reinforcing agent for rubber, making rubber have good corrosion resistance, tear resistance, elasticity, and elongation properties; this product is a multi-functional rubber compounding agent, mainly used in natural rubber, synthetic rubber, and latex as a vulcanization activator and reinforcing agent. When used as a vulcanization activator, the rubber is evenly distributed, with a large contact area with hydrogen sulfide, and a greater chance of interfacial reaction. Coupled with the auxiliary catalytic action of the active substance of the indirect zinc oxide product, the conversion rate of zinc oxide to zinc sulfide is higher.

　　The role of indirect zinc oxide in synthetic rubber: as an activator, vulcanization accelerator, and reinforcing agent, it has a dyeing effect. It enhances the vulcanization activation, reinforcement, and anti-aging effects of rubber, strengthens the vulcanization process, and improves the tear resistance and wear resistance of rubber products.

　　The role of indirect zinc oxide in natural rubber: as a vulcanization activator, it promotes the vulcanization, activation, reinforcement, and anti-aging effects of rubber, strengthens the vulcanization process, and improves the tear resistance and wear resistance of rubber products.

　　The role of zinc oxide in natural latex: as an activator, it promotes the vulcanization, activation, reinforcement, and anti-aging effects of rubber, strengthens the vulcanization process, and improves the tear resistance and wear resistance of rubber products.

　　 indirect zinc oxide Role in the footwear industry (labor protection products, such as rubber shoes, rain boots, rubber gloves, etc.): improve wear resistance and anti-aging ability, and extend service life.
