  • Applications

    2,4,8,10-Tetraoxa-3,9-diphosphaspiro(5.5)undecane, 3,9-bis(2,4-bis(1-methyl-1-phenylethyl)phenoxy)- is an organophosphorus compound typically used as a flame-retardant additive and stabilizer in polymer formulations, including plastics and coatings, where it can also serve as an intermediate in the synthesis of specialty polymers and as a high-temperature stabilizer for polyolefins and PVC; in coatings and inks it can enhance fire performance and thermal resistance, and in adhesives it supports formulation stability. CAS number: 154862-43-8.
