Description

Tris[2-[[2,4,8,10-Tetra-tert-butyldibenzo[D,F][1,3,2]dioxaphosphepin-6-yl]oxy]ethyl]amine is a high-performance, sterically hindered organophosphorus compound, specifically a phosphite antioxidant. Its value lies in its exceptional ability to act as a highly effective secondary antioxidant and process stabilizer, preventing polymer degradation during high-temperature processing and extending material lifespan. This product is essential for manufacturers in the polymer and plastics industries who require superior thermal stability and color retention in their final products. Its unique molecular structure provides excellent hydrolytic stability compared to simpler phosphites.

Application

• Primary application as a secondary antioxidant and process stabilizer in polyolefins (PP, PE), engineering plastics, and synthetic rubbers.
• Used to prevent thermal and oxidative degradation during polymer extrusion, injection molding, and other high-temperature manufacturing processes.
• Effective in stabilizing color and maintaining physical properties in pigmented and filled polymer compounds.
• Employed in adhesive and sealant formulations to enhance long-term stability.
• Acts as a synergist with primary phenolic antioxidants (e.g., hindered phenols) to provide comprehensive stabilization packages.
• Suitable for applications requiring low volatility and high performance in demanding processing conditions.
• Used in the production of food-contact compliant polymers, subject to appropriate regulatory approvals and specific grades.
• Potential use as a ligand or intermediate in advanced organometallic chemistry and catalysis research.
