Aging phenomena such as cracking, hardening, sticking, powdering, and decreased tear strength under repeated deformation conditions are called fatigue aging. Not only rubber seals, but also rubber products in actual use have a lot of fatigue aging, such as mobile phone accessories, shockproof rubber products, etc.

Therefore, when designing a rubber seal with good fatigue anti-aging performance, the formula and process should be designed from the aspects of rubber type, cross-linking agent and curing system, filler, anti-aging agent, processing technology, etc. The design of the rubber seal anti-aging agent system is an effective way to improve the fatigue life of rubber. Its main function is the stability of the rubber seal under fatigue state.
