Antioxidants are chemical additives that effectively delay or inhibit the auto-oxidative degradation of materials (especially polymers, oils, etc.) in the presence of oxygen. They act as "loyal guardians," protecting the matrix material by interrupting free radical chain reactions, significantly extending its service life and maintaining key performance characteristics.

Antioxidants are crucial additives that prevent or delay the aging and degradation of materials due to oxidation. In plastics, rubber, lubricants, fuels, and polymers, oxygen, heat, and light can trigger free radical chain reactions, leading to discoloration, brittleness, performance degradation, and even failure.
Our antioxidant series offers a comprehensive solution of primary antioxidants (free radical scavengers) and secondary antioxidants (hydroperoxide decomposers), effectively interrupting the oxidation process and significantly improving the thermal stability, processing stability, and long-term service life of products. Choosing high-performance antioxidants is the first line of defense in ensuring your products maintain superior performance and reliable quality in harsh environments.

Many organic materials are subjected to heat, light, mechanical stress, or metal ions during processing, storage, and use, generating unstable free radicals. These free radicals react with oxygen in a chain reaction, leading to: performance degradation (decreased strength and elasticity, becoming brittle and sticky); appearance changes (yellowing, surface cracking, loss of luster); and functional loss (deterioration of electrical properties, failure of seals or insulation).
This process is called "aging." Antioxidants are the most economical and effective means of combating aging and maintaining the value of materials.
