Import 4,4'-Methylenebis(2,6-Di-Tert-Butylphenol) — Buy in Bulk from Supplier in China

4,4'-Methylenebis(2,6-di-tert-butylphenol) is a hindered phenolic antioxidant, widely used to stabilise polymers, rubbers and organic substrates against oxidative degradation. This compound, also known by its trade names Antioxidant 728 and Ralox 02 S, features a symmetrical structure with two sterically hindered phenol groups linked by a methylene bridge, providing high thermal stability and low volatility. Its molecular formula is C29H44O2, and it typically appears as a white to off-white crystalline powder.

The product is a high-purity antioxidant, standard for industrial applications where resistance to heat and oxygen is critical. Typical purity for commercial grades is above 98%, with melting point in the range of 154 - 158°C. It is soluble in common organic solvents like toluene and ethyl acetate but insoluble in water, making it suitable for hydrocarbon-based systems. Industry-standard applications include polyolefins, adhesives, lubricants and synthetic fibres.

Importers source this antioxidant for use in polymer processing, where it prevents discolouration and extends the lifespan of the final product. Bulk buyers often request it in 25 kg paper bags or fibre drums, with storage recommendations to keep it in a cool, dry place away from direct sunlight. Confirm packaging, handling and compliance with local regulations before ordering, as specifications may vary by batch.
