Description

4,4'-[[6-(Octylthio)-1,3,5-Triazine-2,4-Diyl]Bis(Oxy)]Bis[2,6-Di-tert-Butylphenol] is a high-performance, hindered phenolic antioxidant synergist that provides exceptional thermal and oxidative stability to a wide range of polymeric materials. Its molecular structure, which combines a triazine core with bulky phenolic groups, makes it particularly effective at scavenging free radicals and preventing polymer degradation under demanding conditions. This compound is essential for formulators and manufacturers in the plastics, rubber, and lubricant industries seeking to extend product lifespan and maintain material integrity.

Application

• Polymer Stabilization: Primary application as a highly effective antioxidant and light stabilizer in polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Used as an antioxidant additive in engine oils, industrial lubricants, greases, and fuels to inhibit oxidation, reduce sludge formation, and extend service intervals.
• Adhesive & Sealant Formulations: Enhances the long-term stability and performance of hot-melt adhesives, pressure-sensitive adhesives, and elastomeric sealants by protecting against heat-induced breakdown.
• Wire & Cable Insulation: Provides critical protection for polyethylene and cross-linked polyethylene (XLPE) insulation used in wires and cables, safeguarding against oxidative embrittlement caused by elevated operating temperatures.
• Synergistic Blends: Often used in combination with primary antioxidants (e.g., phosphites, thioesters) and UV stabilizers to create synergistic stabilization systems for enhanced performance.
• Elastomer Manufacturing: Protects synthetic rubbers like SBR, BR, and NBR during mastication, compounding, and in finished goods such as automotive belts, hoses, and gaskets.
