Product Name:2,2'-Methylenebis(4,6-di-tert-butylphenol)
English Name:2,2'-Methylenebis(4,6-di-tert-butylphenol)
CAS No.:38486-51-0
Aliases:Antioxidant 2246A, 2,2'-Methylenebis(4,6-di-tert-butylphenol)
Molecular Formula:C29H44O2
Physical Properties:White or slightly yellow crystalline powder, molecular weight 424.66, melting point approximately 155-158°C, readily soluble in organic solvents such as benzene, acetone, and ethanol, insoluble in water. As a hindered phenolic antioxidant, it features low volatility, excellent thermal stability, and high antioxidant efficiency.
Uses:Used as an antioxidant and anti-aging agent for polymer materials, widely applicable to natural rubber, synthetic rubber, polyolefin plastics, and elastomers. It effectively inhibits thermal-oxidative aging and extends the service life of materials, especially suitable for light-colored and colored rubber products.
Technical Specifications:
Appearance: white or slightly yellow crystalline powder
Melting point: 155-158°C
Ash content: ≤0.3%
Loss on heating: ≤0.5%
Purity: ≥98.0%
