How To Enhance The Aging Resistance Of Rubber Seals?

Rubber seals are sealing products with good elasticity. Smaller stress in different media will produce large deformation. This deformation can provide contact pressure, compensate for leakage gaps, and achieve the purpose of sealing.

In the process of using rubber seals, aging and failure often occur. Except for the case where the working conditions cannot be changed during use, it is necessary to strengthen the anti-aging performance in the production design of rubber seals.

The aging phenomenon of cracking, hardening, sticking, powdering, and tearing strength reduction of rubber seals under the condition of repeated deformation is called fatigue aging. Not only rubber seals, but also many rubber products that are actually used have fatigue and aging, such as automobile tires, rubber conveyor belts, shock-proof rubber products, rubber fitness equipment and so on.

Therefore, when designing rubber seals with excellent fatigue and aging resistance, the formulation and processing technology should be designed from the type of rubber compound, crosslinking agent and vulcanization system, filler, type of antioxidant, and processing technology. The system design of anti-aging additives for rubber seals is a more effective way to improve the fatigue life of rubber. Its main function is the stability of structural changes in the fatigue process of rubber seals. Especially under higher temperature conditions, anti-aging additives can effectively hinder the It works by mechanically activating the oxidation reaction.
