Description

4,4',4''-[(2-Methoxy-4,6-Dimethylbenzene-1,3,5-Triyl)Tris(Methylene)]Tris[2,6-Di-tert-Butylphenol] is a high-performance, sterically hindered phenolic antioxidant. This compound is valued for its exceptional ability to inhibit oxidative degradation in polymers and other organic materials, thereby extending their service life and maintaining their physical properties. It is a critical additive for manufacturers in the polymer, rubber, and specialty chemical industries who require reliable stabilization against thermal and oxidative stress.

Application

• Primary antioxidant for the stabilization of polyolefins (e.g., PP, PE) against thermal oxidation during processing and long-term use.
• Key additive in synthetic rubber and elastomer formulations to prevent chain scission and cross-linking.
• Stabilizer for engineering plastics and thermoplastic elastomers (TPEs) to enhance durability and color retention.
• Used in lubricants, greases, and transformer oils to inhibit oxidation and sludge formation.
• Component in adhesive and sealant formulations to improve aging resistance.
• Stabilizing agent for hydrocarbon-based fuels and other petrochemical derivatives.

Quality Control

Our production of 4,4',4''-[(2-Methoxy-4,6-Dimethylbenzene-1,3,5-Triyl)Tris(Methylene)]Tris[2,6-Di-tert-Butylphenol] adheres to a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for industrial applications. Certificates of Analysis (COA) detailing purity, identity, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep away from strong oxidizing agents.
