Tri-Octyl Trimellitate, also known as TOTM, is used as a plasticizer in the production of PVC and other copolymers. TOTM is ideal when low volatility is required such as wiring, cabling and automotive interior. It can be blended with other general-purpose plasticizers such as DUP or DOTP to lower volatility. It is used in a variety of processes such as calendering, extrusion and injection molding.
