This product boasts a unique “one-agent, dual-effect” capability: not only does it retain the core functions of conventional hindered phenol antioxidants—such as scavenging free radicals and delaying thermo-oxidative aging—but its molecular structure also incorporates a UV-absorbing group, giving it simultaneous UV absorption capacity and thus providing dual protection against thermal degradation and photooxidation.

Technical requirements:

Use:This productSuitable for a wide variety of polymeric materials, including primarily polyolefins (such as polyethylene and polypropylene), polystyrene, ABS resin, polyurethane, polyester, and polyamide fibers. It offers excellent resistance to yellowing and provides superior surface protection. Its outstanding anti-yellowing performance makes it particularly well-suited for transparent or light-colored products, as well as applications with stringent appearance requirements—such as automotive interior parts and light-colored home appliance components. It effectively inhibits “gas-induced discoloration” caused by acidic gases like nitrogen oxides. As a highly efficient free-radical scavenger, even at extremely low addition levels (0.02%–0.15%), it can significantly extend the oxidation induction period of materials, providing exceptional long-term thermal protection. Moreover, this antioxidant exhibits excellent resistance to extraction, helping maintain its effective concentration over extended periods of use or exposure to various media.
