Antioxidant BBM CAS NO.85-60-9

Antioxidant BBM CAS NO.85-60-9 is a hindered phenolic stabiliser with the chemical name 1,1-bis(2-methyl-4-hydroxy-5-tert-butylphenyl)butane. It appears as a white powder with a molecular formula of C26H38O2 and a molecular weight of 382.58. The product exhibits an initial melting point of 208°C minimum, an ash content of 0.05% maximum, and a loss on heating of 0.3% maximum, with a grain size of 1mm at 100%. It is soluble in organic solvents and remains stable under high-temperature processing without decomposition.

This antioxidant is designed for use as a stabiliser and protective agent in polymers, including ABS, PP, PE, PVC, SBS, and PAN, as well as in synthetic rubber. It delivers strong oxidation resistance and works synergistically with thioester antioxidants such as DLTDP and DSTDP, as well as UV absorbers, to enhance performance. A standard feature of hindered phenolic antioxidants is their ability to inhibit oxidation by scavenging free radicals, which is critical in preventing polymer degradation. BBM also offers metal ion passivation, making it suitable for polyolefin and cable production where metal contamination can accelerate degradation.

Manufacturers in the plastics, rubber, and cable industries rely on BBM to extend the lifespan of their products by preventing discolouration and maintaining mechanical properties. Typical applications include automotive components, packaging materials, and electrical insulation. Buyers sourcing this additive should confirm compatibility with their specific polymer matrix and processing conditions, as well as the required purity levels for their end use. The product is commonly supplied in 25 kg paper bags with polyethylene liners, a standard packaging format for industrial antioxidants.
