Description

Phenol, 2-4,6-Bis(2,4-Dimethylphenyl)-1,3,5-Triazin-2-Yl-5-3-(2-Ethylhexyl)Oxy-2-Hydroxypropoxy- is a high-performance, sterically hindered phenolic antioxidant and light stabilizer. This compound is engineered to provide exceptional long-term thermal stability and ultraviolet (UV) light protection for sensitive polymer systems. It is a critical additive for manufacturers in the plastics, coatings, and specialty chemical industries who require reliable protection against oxidative degradation and color fading. The product, identified by CAS No. 137658-79-8, is supplied to meet the stringent quality demands of industrial applications.

Application

This multifunctional phenolic antioxidant is primarily utilized as a stabilizer in polymer formulations. Its key applications include:

• Polyolefin Stabilization: Providing long-term thermal aging protection for polypropylene (PP) and polyethylene (PE) in automotive parts, fibers, and packaging films.
• Engineering Plastics Additive: Enhancing the durability and color retention of polyamides (PA), polyesters (PET, PBT), and polycarbonates (PC) used in electrical components and consumer goods.
• Adhesive & Sealant Formulations: Preventing oxidative cross-linking and embrittlement in hot-melt adhesives, sealants, and elastomers.
• Synthetic Fiber Production: Protecting fibers like polypropylene and nylon from degradation during high-temperature melt processing and end-use.
• Coating & Ink Stabilizer: Used in solvent-based and high-solid coatings to inhibit polymer degradation and maintain film integrity.
• Synergistic Blends: Often combined with primary antioxidants (e.g., phosphites) and HALS (Hindered Amine Light Stabilizers) for superior stabilization packages.
