2,2'-methylenebis(4-methyl-6-tert-butylphenol)

2,2'-Methylenebis(4-methyl-6-tert-butylphenol) , also known by CAS 119-47-1 , is a hindered bisphenol antioxidant used to protect organic materials from oxidative degradation. It functions as a primary antioxidant by scavenging free radicals in polymer matrices and rubber compounds. In rubber and tire manufacturing, this chemical protects vulcanized compounds from heat aging and flex cracking, extending service life in dynamic applications. Polymer processors incorporate it into polyolefins and ABS to maintain mechanical integrity. The additive is essential during high-temperature extrusion and molding processes to prevent material failure. Lubricant and metalworking fluid formulators use it to inhibit oxidative breakdown in mineral and synthetic base oils under sustained thermal stress. Adhesive and sealant manufacturers add it to prevent premature degradation in elastomeric systems exposed to elevated temperatures. It is particularly effective during UV-assisted aging cycles where material stability is critical for long-term performance. The product is supplied as a white to off-white crystalline powder for industrial use. It is available in technical and polymer-grade specifications, with purity levels typically at 99% or higher confirmed by standard analytical methods. Packaging ranges from multi-layer bags for bulk industrial supply to smaller quantities for laboratory and formulation development use. This ensures the material remains stable and easy to handle across various manufacturing environments and scales.
