  • Applications

    Trioleyl Phosphate (CAS 3305-68-8) is primarily used as a plasticizer for PVC and other polymers, improving flexibility and processability of films and coatings. It also serves as a flame-retardant additive in polymer matrices, textiles, and coatings. As a processing aid and formulation component, it enhances flow and compatibility in coatings, adhesives, and resins. It can function as a lubricity additive or component in specialty lubricants and metalworking fluids, contributing to high-temperature performance. Additionally, it is used as an intermediate in the synthesis of other organophosphorus esters and phosphorus-containing additives.
