  • Applications

    P,P'-(Butylidenebis(2-(1,1-dimethylethyl)-5-methyl-4,1-phenylene)) bis(P,P-ditridecyl phosphite) (CAS 13003-12-8) is a diaryl phosphite stabilizer used primarily as a processing and storage antioxidant in polymer systems. It functions as a hydroperoxide scavenger and radical-trapping additive to improve thermal stability and color retention of plastics during extrusion, molding and aging, especially in polyolefins and other commodity polymers. In practice it is commonly employed as a secondary stabilizer in combination with hindered phenolic antioxidants, and is also used in coatings, inks and adhesives based on polymer substrates to enhance long-term stability. It may also find use in elastomer formulations and lubricant additive packages as a stabilizer, and in certain electronic-grade polymer resins where oxidative degradation is a concern; usage is subject to local regulations and formulation limits.
