Buy 2,2'-Methylenebis(4-methyl-6-tert-butylphenol) Antioxidant 2246 CAS 119-47-1 China supplier
2,2'-Methylenebis(4-methyl-6-tert-butylphenol) is a synthetic phenolic antioxidant with a molecular structure that provides thermal and oxidative stability to organic materials. Also known by trade names (e.g., Anox 22, Lowinox MBM), it is widely used in industries requiring protection against degradation from heat, light, or chemical oxidation. Below are its key applications in English contexts:
Plastics and Rubber Additive
Thermal Stabilizer in Polymers: Used in polyolefins (e.g., PE, PP), polystyrene (PS), ABS, and synthetic rubbers (e.g., SBR, EPDM) to prevent chain scission and cross-linking during processing (e.g., extrusion, injection molding) and long-term use.
Anti-Aging Agent: Inhibits oxidative degradation in automotive parts, electrical insulation, pipes, and packaging materials, extending service life and maintaining mechanical properties (e.g., tensile strength, flexibility).
PVC and Polyurethane: Stabilizes flexible PVC compounds (e.g., cables, flooring) and polyurethane foams (e.g., furniture, automotive seats) against heat and oxidative stress.
Motor Oils and Industrial Lubricants
Antioxidant in Lubricants: Prevents the formation of sludge, varnish, and acid byproducts in engine oils, hydraulic fluids, and greases, enhancing lubricant longevity and reducing maintenance costs.
Fuel Stabilizers: Added to gasoline, diesel, and biofuels to inhibit gum formation and oxidative degradation during storage, ensuring fuel quality and engine performance.
Synthetic Fibers (e.g., Nylon, Polyester)
Protects fibers from oxidative damage during spinning and processing, maintaining colorfastness and resistance to mechanical stress in textiles, carpets, and industrial fabrics.
Petroleum Products: Used in waxes, resins, and bitumen to improve thermal stability and resistance to weathering in applications like roofing materials and road paving.
Thermosetting Resins (e.g., Epoxy, Phenolic)
Prevents oxidative degradation in adhesives, paints, and varnishes, improving shelf life and performance in high-temperature environments (e.g., industrial coatings, aerospace adhesives).
Pressure-Sensitive Tapes: Stabilizes rubber-based adhesives against aging, maintaining tackiness and adhesion over time.
Pharmaceutical Excipients
Pesticide Formulations: Stabilizes oil-based insecticides and herbicides, preventing degradation of active components in agricultural sprays.
