The Use of Zinc Oxide in the Rubber Industry: Common Applications to Know

Zinc oxide is critical in the rubber industry since the property is the main accelerator in the process of vulcanization. It is also an important material in most rubber products and affects the finished products. This page will discuss more about the use of zinc oxide in the rubber industry as well as its common application.

How Is It Applicated in the Industry?

Many rubber products use zinc oxide as the main ingredient. These include truck and passenger car tires, hoses, belts, and gaskets. You will also find zinc oxide in some other rubber products including door channels, window channels, shoe soles, heels, boots, wire, inflatable boats carpet backing, cable, rubber jackets, and more.

Zinc Oxide is the Preferred Activator

When it comes to curing or vulcanization, the use of zinc oxide in the rubber industry is much more preferable. Some of the reasons that zinc oxide is popular in the industry include:

  • Zinc oxide is known to improve the effect of organic accelerators during the vulcanization process of rubber.
  • Another reason to use zinc oxide in the rubber industryis that the property can add strength to rubber compounds effectively. As a result, the resistance of the rubber to abrasion and heat is improved significantly. Not only that but the property can also protect rubber from ultraviolet degradation.
  • The rubber industry also uses zinc oxide to break both the accelerator and the sulfur reticulation.
  • Rubber is quite prone to shrinkage. However, the application of zinc oxide in manufacturing can help minimize the risks of shrinkage.
  • Heat is the number one enemy of rubber but zinc oxide can reduce it significantly. As a result, wear in tires due to heat buildup can also be minimized.
  • When it comes to achieving the necessary degree of reticulation, zinc oxide is highly effective. This is possible since the property can form cross-links between polymer chains that is very important in the rubber vulcanization process.
