    Application:

    Trioctyl trimellitate(TOTM) used as a heat-endurant and long-lasting plasticizer for polyvinyl chloride,usually for preparing

    Grade 105℃ electrical cable and other heat-resisting plastic products.It possesses both advantages being used as plasticizer

    for polyesters and for general purposes. Except producing oilresisting ones,also used in preparing any long-lasting products.
