Alkylated diphenylamine

Antioxidant 5057 (CAS: 68411-46-1) is a commercially important chemical raw material used in amine-based rubber antioxidant. It is valued for its defined or controlled composition, dependable processing behavior, and ability to support consistent quality in demanding industrial formulations. The material is identified by the molecular formula Variable proprietary mixture and a molecular weight of approximately Variable g/mol where applicable. For polymeric or proprietary products, the composition and molecular weight may be represented as variable or specification-dependent rather than as one discrete molecular species. In practical manufacturing, Antioxidant 5057 can help improve resistance to heat, oxygen, ozone, flex fatigue, aging, or other stresses that reduce the service life of finished products. It is commonly evaluated by purity, active content, ash, melting or softening behavior, color, compatibility, dispersion, and batch-to-batch consistency. Proper grade selection allows formulators to balance performance, processing safety, finished-product appearance, and cost while maintaining a stable production process.
