1. Core protection for rubber products: anti-aging and extended service life
This is its main application, providing critical protection against the aging problems of rubber caused by "heat, ozone, and oxidation" during use (such as hardening, cracking, and reduced elasticity).
Tire manufacturing: It is used in the tread and sidewall rubber compounds of various types of tires such as cars, trucks, and construction machinery to resist the heat generated by friction during vehicle operation and the erosion of ozone in the atmosphere, delay the aging and cracking of tires, and extend their service life.
Industrial rubber products: Suitable for rubber hoses (such as oil and gas pipelines), conveyor belts (for mining and logistics), and seals (O-rings, gaskets), to prevent these products from premature aging and failure when exposed to outdoor or harsh environments (such as high temperatures and humidity) for a long time.
Daily-use/special rubber products: used for wiper rubber strips, rubber gaskets, shock-absorbing rubber (for automobiles/machinery), as well as products made of synthetic rubber such as chloroprene rubber and styrene-butadiene rubber, maintaining their long-term elasticity and performance in use.
2. Rubber protection supplements for specific scenarios
In addition to general protection, specific aging problems can also be specifically addressed based on the usage environment of rubber products:
Anti-dynamic fatigue aging: It is used for rubber components that need to be subjected to repeated forces (such as conveyor belts and shock absorbers), reducing "fatigue cracking" caused by the combined effect of dynamic stress and oxidation.
High-temperature protection assistance: In rubber products used in medium and high-temperature environments (such as engine peripheral seals), when compounded with other antioxidants, it enhances the rubber's heat oxidation resistance and prevents it from rapidly hardening and becoming brittle at high temperatures.
