Product Name:Antioxidant 630
English Name:Antioxidant 630
CAS No.:69439-68-5
Aliases:Tris(2,6-di-tert-butyl-4-methylphenyl) phosphite, Phosphorous acid tris(2,6-di-tert-butyl-4-methylphenyl) ester
Molecular Formula:C45H69O3P
Physical Properties:White crystalline powder; insoluble in water, soluble in toluene, acetone, ethanol, ethyl acetate and other organic solvents. It has a relatively high melting point, good thermal stability, low volatility, and excellent resistance to hydrolysis and oxidation.
Uses:As a polymer antioxidant, it is mainly used for processing stabilization of polyolefins, polyesters, nylon and other plastics and elastomers, effectively inhibiting thermal oxidative degradation. It shows good synergistic effects when combined with hindered phenolic antioxidants, and is suitable for high-temperature processing and long-term service applications.
Technical Specifications:
Appearance: White crystalline powder or granules
Assay: ≥98.0%
Melting point: 180～190℃
Volatile content: ≤0.5%
Solubility: Insoluble in water, soluble in toluene, acetone, ethyl acetate and other organic solvents
