Trioctyl trimellitate (Cat No.: R016393) is a high-performance plasticizer derived from trimellitic acid and octanol. It features three octyl ester groups attached to a trimellitate core, offering excellent flexibility, low volatility, and thermal stability. TOTM is widely used in the production of flexible PVC, especially for medical devices, wire and cable insulation, and automotive applications where long-term durability and resistance to extraction by oils or solvents are critical. Its low migration rate and high resistance to heat make it suitable for demanding industrial environments.
