Antioxidant 300

Product Overview

Antioxidant 300, chemically identified as 4,4'-Thiobis(6-tert-butyl-m-cresol), stands as a premier solution in the realm of polymer stabilization and protective additives. This high-efficiency hindered phenol antioxidant is specifically engineered to prevent thermo-oxidative degradation in a wide variety of synthetic materials. With the CAS registry number 96-69-5, this compound has established itself as an industry standard for manufacturers seeking reliable protection against aging and environmental stressors in plastic and rubber formulations.

Our manufacturing process ensures exceptional purity and consistency, making Antioxidant 300 suitable for sensitive applications including food packaging materials where regulatory compliance is paramount. The product exhibits superior solubility and compatibility within polymer matrices, ensuring uniform dispersion without compromising the physical properties of the final product.

Key Performance Characteristics

The molecular structure of Antioxidant 300 provides robust protection against free radical formation during processing and end-use conditions. Unlike many conventional stabilizers, this compound is non-staining and non-discoloring, which is critical for maintaining the aesthetic quality of light-colored or transparent polymers. Its hindered phenol chemistry offers excellent resistance to washout, ensuring long-term stability even in environments exposed to moisture or extraction processes.

Furthermore, Antioxidant 300 demonstrates great synergism when used in combination with carbon black and other stabilizers. This compatibility allows formulators to optimize their additive packages for maximum performance while minimizing overall costs. The compound also acts as an effective anti-skinning agent in hot melt adhesives and serves as a heat stabilizer in lubricant formulations, showcasing its versatility across multiple industrial sectors.

Industrial Applications

This specialty chemical is extensively utilized in the stabilization of polyolefins such as HDPE and LDPE. It is particularly effective in the production of tubes, water and gas pipes, connectors, high voltage cables, and greenhouse films. The additive protects these materials from degradation during high-temperature processing and extends their service life under operational stress.

Beyond polymers, Antioxidant 300 functions as a polymerization and processing stabilizer for engineering plastics including PP, ABS, PVC, EPDM, and polybutadienes. In the adhesive industry, it prevents skinning during storage, while in polyurethane production, it acts as an anti-scorching agent during the condensation of TDI on polyesters. Its approval for food packaging use in many countries further expands its applicability in consumer goods and safety-critical materials.
