  • Applications

    Tridodecyl phosphate, CAS 682-49-5, is primarily used as a plasticizer for PVC and other polymers to improve flexibility, processing, and handleability. It is also used as a processing aid in coatings and inks to improve film formation and finish. The compound can act as a heat stabilizer in PVC formulations, enhancing thermal stability during processing. It may function as a lubricant or sliding additive in polymer processing or lubricant systems to reduce friction. It can also serve as a flame-retardant additive in polymers and coatings, contributing to lower flammability in certain resin systems. In some solvent-based formulations it may act as a solvent or carrier for formulation components, given its high boiling point and compatibility with selected polymers.
