Why is zinc oxide used in rubber? We will help you learn more about the reasons. More importantly, we will show you the benefits of zinc oxide or ZnO usage in rubber product manufacturing. 

Reinforcing Agent

You find it a lot in tire manufacturing. ZnO is used as a reinforcing agent. This is necessary because tires are used and function in various extreme conditions.

Zinc oxide delivers power and enhances the tires’ durability. Thus, the high temperature and friction that tires experience when used on a vehicle won’t cause too much damage to them.

This application prolongs the tire’s lifespan and maintains its shape. That reduces the risk of accidents greatly.

Ultraviolet (UV) Protection

People are familiar with UV protection for the skin. But, that’s not all. Rubber also needs it.

Zinc oxide works as a guard to protect rubber against UV exposure. For your information, UV radiation could cause damage to rubber material. It happens a lot on rubber products that you use outdoors.

Some damages caused by UV are deterioration or reduced performance. They can cause accidents and harm users. So, adding ZnO to rubber will solve these problems.

Antioxidant and Anti-aging

ZnO adds antioxidant and anti-aging properties to the rubber product. That is necessary because of rubber characteristics. It loses elasticity over time.

That condition occurs because of oxidation. Therefore, adding zinc oxide can protect it from oxidation. Thus, the problem caused by time is also eliminated.

It also prolongs its lifespan. You don’t need to replace the rubber product too often.

Acid Resistance and Chemical Stability

We use rubber on various products that come into contact with chemical substances. Many of those chemical substances have dangerous effects. They damage the rubber.

Zinc oxide helps to create acid resistance. More importantly, it adds chemical stability, which improves the rubber’s durability against chemical substances. Thus, it also protects the user of rubber products.

Improve Compounding Process

The compounding procedure mixes rubber and numerous different components. There is a risk of failure during the blending process. The rubber material is unable to achieve optimal vulcanization.

Zinc oxide solves that problem. It stabilizes the process to reach the vulcanization result. The rubber end product will have better strength and heat resistance.

Final Words

In short, zinc oxide used in rubber offers many benefits. We hope this article helps you understand the greatness of zinc oxide in the rubber manufacturing industry.
