General description

Trioctyl trimellitate (TOTM) is a flammable plasticizer used to improve the flexibility and durability of poly(vinyl chloride) (PVC).

Application

TOTM can plasticize PVC to form a nanocomposite with multi-walled carbon nanotube which can be potentially used for anti-static applications.

Storage Class

10 - Combustible liquids

The results of these studies demonstrate that Tri(2-ethylhexyl)trimellitate (TOTM) produces the sam spectrum of morphological and biochemical changes in the rat liver as di(2-ethylhexyl)phthalate (DEHP). TOTM, however, was much less potent in its action, with a dietary level of 2.0%
