Antioxidant 1520 (chemical name: 2,4-bis(n-octylthiomethyl)-6-methylphenol, CAS NO. 110553-27-0) is a highly efficient multifunctional antioxidant that combines the dual functions of primary and secondary antioxidants. Its molecular structure contains phenolic hydroxyl and sulfur groups, which can interrupt the oxidative chain reaction by scavenging free radicals and decomposing peroxides, thereby effectively delaying the oxidative degradation of polymers, rubbers, plastics, and other materials during processing or use.

Performance Characteristics:
Antioxidant 1520 is known for its high thermal stability, low volatility, and excellent dispersibility, especially maintaining superior performance under high temperature and high humidity conditions. Its low migration and environmental characteristics meet the sustainable development requirements of modern industry, promoting the transition of rubber products from general-purpose to environmentally friendly types. Additionally, when used in synergy with phosphate antioxidants (such as TNPP), it can significantly enhance the antioxidant effect.

Applications:

Rubber Industry: Widely used in synthetic rubbers such as polybutadiene, styrene-butadiene, and ethylene-propylene rubber to prevent oxidative aging, gel formation, and color changes, extending the service life of products.

Plastics Industry: Inhibits oxidative degradation of plastics such as polyethylene and polypropylene during high-temperature processing, improving weather resistance and stability.

Coatings and Inks: Prevents oxidative discoloration and cracking of coatings, enhancing gloss and durability.

Market Prospects:
The demand for Antioxidant 1520 is growing rapidly, driven by the expansion of the rubber and plastics industries and the promotion of environmental policies. The global market is also showing steady growth, with environmentally friendly antioxidants expected to dominate future industry upgrades.

With its high efficiency and environmental advantages, Antioxidant 1520 has become an indispensable additive in the field of material protection, with significant future development potential.
