Triamyl phosphate is primarily used as a plasticizer in the production of various polymers, enhancing their flexibility, durability, and workability. It is particularly effective in polyvinyl chloride (PVC) applications, where it improves the material's performance in products like cables, flooring, and synthetic leather. Additionally, it serves as a solvent and extractant in chemical processes, aiding in the separation and purification of specific compounds. Its stability and compatibility with other chemicals make it a valuable component in lubricants and hydraulic fluids, where it helps reduce friction and wear. In some cases, it is also employed as a flame retardant additive, contributing to the fire resistance of materials.
