Description

Product Detail

1. Chemical Identity

• IUPAC Name: 2,2'-Methylenebis(6-tert-butyl-4-ethylphenol)

• CAS Registry Number: 5162-44-7

• Molecular Formula: C₂₇H₄₀O₂

• Molecular Weight: 396.61 g/mol

• Common Commercial Names: This compound is a hindered bisphenolic antioxidant, sometimes referred to by designations like Antioxidant 425 or similar codes in industrial contexts.

2. Primary Function: Antioxidant

This compound is a hindered phenolic antioxidant that acts primarily as a radical scavenger. It inhibits oxidative degradation by donating hydrogen atoms to free radicals (e.g., peroxyl radicals, ROO•), thereby interrupting the chain reaction that leads to polymer deterioration.

3. Key Properties and Advantages

• Thermal Stability: Its molecular structure ensures low volatility and effectiveness at high processing temperatures.

• Compatibility: Demonstrates good solubility in polyolefins, elastomers, and oils, reducing the risk of blooming or exudation.

• Color Stability: Helps prevent yellowing and discoloration in final products.

• Broad-Spectrum Efficacy: Protects against both processing-induced and long-term thermal oxidation.

4. Main Applications

• Polymers: Widely used in polypropylene (PP), polyethylene (PE), and engineering plastics to maintain mechanical properties during processing and service life.

• Elastomers: Stabilizes natural and synthetic rubbers (e.g., SBR, EPDM) against aging.

• Lubricants and Oils: Functions as an antioxidant in industrial lubricants, greases, and transformer oils.

• Adhesives and Waxes: Prevents degradation in hot-melt adhesives and synthetic waxes.
