Widely used in the rubber industry to protect products from oxidative degradation caused by heat, light, and atmospheric oxygen. It is particularly effective in tires, hoses, belts, and other rubber goods exposed to high temperatures and stress. Helps extend service life by preventing cracking, hardening, and loss of mechanical strength. Also used in polymer systems where long-term thermal stability is required. Compatible with various elastomers, including natural rubber, SBR, and EPDM. Commonly selected for dynamic applications due to its ability to provide protection without sacrificing flexibility or performance.
