Description

2,2',2''-[1,3,5-Triazine-2,4,6-Triyltris[Oxy(3,5-Dimethyl-2,1-Phenylene)(3,5,5-Trimethylhexylidene)]]Tris[4,6-Xylenol] is a high-performance phenolic antioxidant and light stabilizer belonging to the hindered amine light stabilizer (HALS) family, with CAS number 85279-89-6. Its complex molecular structure provides exceptional long-term thermal stability and protection against UV degradation for sensitive polymer matrices. This compound is essential for formulators and manufacturers in the plastics and polymer industries seeking to enhance the durability and lifespan of their products under demanding environmental conditions.

Application

• Polymer Stabilization: Primary application as a highly effective antioxidant and light stabilizer in polyolefins (PP, PE), engineering plastics, and synthetic fibers to prevent thermal-oxidative degradation and UV-induced chain scission.
• Automotive Components: Used in exterior plastic parts, under-the-hood components, and interior trim to ensure color retention, mechanical integrity, and resistance to heat and sunlight.
• Agricultural Films and Geomembranes: Critical for extending the service life of greenhouse films, mulch films, and pond liners exposed to intense and prolonged solar radiation.
• Wire and Cable Insulation: Imparts long-term thermal aging resistance to insulation and jacketing materials for electrical cables.
• Masterbatch Production: Supplied as a key active ingredient in concentrated additive masterbatches for simplified and uniform dispersion in polymer processing.
• High-Performance Coatings and Adhesives: Enhances the weatherability and prevents chalking and cracking in coatings and adhesive systems for outdoor applications.
