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.
Package and storage
Packed in 200 liter galvanized iron drum,net weight 200 kg/drum.Stored at dry,shady,ventilated place. Prevented from collision
and sunrays,rain-attack during handling and shipping.
