What is 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.
Where is 2,2'-methylenebis(4-methyl-6-tert-butylphenol) used?
- Rubber and tire manufacturing: protects vulcanized compounds from heat aging and flex cracking, extending service life in dynamic applications
- Polyolefins and ABS: maintains mechanical integrity
- High-temperature extrusion and molding: prevents material failure
- Lubricants and metalworking fluids: inhibits oxidative breakdown in mineral and synthetic base oils under sustained thermal stress
- Adhesives and sealants: prevents premature degradation in elastomeric systems exposed to elevated temperatures
- It scavenges free radicals in polymer matrices and rubber compounds.
Commercial specifications
- Purity typically 99% or higher, confirmed by standard analytical methods
- Packaging from multi-layer bags for bulk supply to smaller quantities for laboratory and formulation development
