Description

Phenol, 4-[[Bis(2-Hydroxyethyl)Amino]Methyl]-2,6-Bis(1,1-Dimethylethyl)- is a hindered phenolic compound that functions as a highly effective antioxidant and stabilizer. Its molecular structure is engineered to provide superior protection against oxidative degradation, making it a critical additive for extending the service life of sensitive materials. This product is essential for manufacturers in the polymer, lubricant, and specialty chemical industries who require reliable stabilization solutions to maintain product integrity and performance under demanding conditions.

Application

• Polymer Stabilizer: Primary antioxidant for polyolefins (PP, PE), polyurethanes, and engineering plastics to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Antioxidant component in synthetic and mineral-based lubricating oils, greases, and industrial fuels to inhibit sludge formation and viscosity increase.
• Rubber Antioxidant: Used in the production of synthetic rubber (SBR, BR) and elastomers to prevent cracking and loss of elasticity caused by oxidation.
• Adhesive & Sealant Formulation: Enhances the shelf-life and thermal stability of hot-melt, pressure-sensitive, and reactive adhesive systems.
• Coating & Resin Additive: Protects acrylic, alkyd, and polyester-based coatings and resins from yellowing and embrittlement due to UV and oxidative exposure.
• Intermediate for Specialty Chemicals: Serves as a key building block in the synthesis of more complex antioxidants, light stabilizers, and pharmaceutical intermediates.
