Description

2,6-Di(tert-Butyl)-4-(2,4,6-Trimethylbenzyl)Phenol is a high-performance hindered phenolic antioxidant. This compound is valued for its ability to inhibit oxidative degradation and extend the service life of polymers and other sensitive materials. It is a critical additive for manufacturers in the polymer, rubber, and specialty chemical industries seeking to enhance product stability and performance under demanding conditions.

Application

• Primary antioxidant and stabilizer in polyolefins (PP, PE), engineering plastics, and synthetic rubbers.
• Additive in lubricants, greases, and transformer oils to prevent oxidation and sludge formation.
• Stabilizing agent in adhesives, sealants, and elastomeric compounds to prevent premature aging.
• Intermediate in the synthesis of more complex, high-molecular-weight phenolic antioxidants.
• Protective additive in fuel and petrochemical products to improve oxidative stability.
• Used in the stabilization of hot-melt adhesives and other thermoplastic applications.

Quality Control

Our 2,6-Di(tert-Butyl)-4-(2,4,6-Trimethylbenzyl)Phenol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets precise specifications for performance as a polymer stabilizer. Certificates of Analysis (COA) documenting identity, purity, and related substances 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, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
