What are the characteristics of rubber seal oxidation and how to delay it?

In industrial equipment and systems, rubber seals play a key sealing role. However, due to long-term exposure to oxygen, rubber seals may oxidize, affecting their performance and life. This article will provide an in-depth introduction to the characteristics of rubber seal oxidation and provide some methods to help delay the oxidation process of rubber seals.

Characteristics of oxidation of rubber seals

1. Hardening and brittleness

During the oxidation process of rubber seals, its molecular chains may be damaged by oxygen, causing the rubber to become hard and brittle. This weakens the elasticity of the rubber, reducing its sealing properties and increasing the risk of leaks.

2. Surface cracks

Oxidation may also cause cracks on the rubber seal surface. These tiny cracks will not only affect the sealing performance, but may also become channels for media penetration, causing leakage problems.

3. Color change

Oxidation can also cause a change in the color of rubber seals, often appearing dark yellow or brown. This is the result of a chemical reaction between oxygen and rubber, indicating that the rubber material is changing.

4. Shortened lifespan

As the degree of oxidation increases, the life of the rubber seal will be shortened. Oxidation causes the rubber to lose its original elasticity and flexibility, making it more susceptible to wear and aging during use, leading to premature failure.

Methods to delay oxidation of rubber seals

1. Storage conditions

When storing rubber seals, avoid direct sunlight and high temperature environments, and maintain ventilation. Avoid storage in an environment containing ozone, as ozone promotes the oxidation of rubber.

2. Use antioxidants

Adding antioxidants to rubber seals is an effective method. Antioxidants can slow down the reaction between rubber materials and oxygen and delay the oxidation process.

3. Regular inspection and maintenance

Regularly check the condition of rubber seals and promptly identify and replace parts showing signs of oxidation. Carry out regular cleaning and maintenance to avoid the adverse effects of contamination and chemicals on rubber.

4. Choose the right materials

When selecting rubber seals, consider choosing materials that are resistant to oxidation. Some rubber materials designed for special environments such as high temperature resistance and corrosion resistance can effectively delay the oxidation process.

in conclusion

Oxidation of rubber seals will affect their performance and life, so it is particularly important to take effective prevention and maintenance measures. By managing storage conditions, adding antioxidants, regular inspections and selecting appropriate materials, the oxidation process of rubber seals can be delayed and ensure their long-term and effective sealing effect in industrial systems.
