Structure and Diffusion Behavior of Trioctyl Trimellitate
Tri-2-ethylhexyltrimellitate (TOTM) is one of the commercially used plasticizers for poly (vinyl chloride) (PVC). In this work, the diffusion behavior of TOTM in PVC films is investigated through real-time ATR-IR spectroscopy at 25, 40, and 70 °C, and the ratio changes of three C═O structures of TOTM are plotted as a function of diffusion time.

CPSC Staff Statement on University of Cincinnati Report
When trimellitate esters, such as TOTM, are processed with PVC, their principle feature is low volatility, even under high temperatures. Consequently, TOTM’s main use is in high specification electrical cable insulation and sheathing (ECPI, 2009, as cited by Versar, 2010). Additionally, as a branched molecule, TOTM is more viscous than the

Trioctyl Trimellitate – Electrical Grade (TOTM-E) - Chemceed
Trioctyl Trimellitate (TOTM) is a high molecular weight, branched plasticizer used for PVC applications in which the end-use requires extreme low volatility. Such applications can include vinyl automotive interior or molded parts, dishwasher gaskets, seals, and telephone wire.
- What is Trioctyl trimellitate (TOTM)?
- Trioctyl trimellitate (TOTM) is a colourless, transparent oily liquid with a boiling point of 283℃ (3mmHg) and a viscosity of 100–300 c.p. (20℃). It has a refractive index of 1.4485 (25℃). TOTM is used as a heat-endurant and long-lasting plasticizer for polyvinyl chloride. It is typically used for preparing plastics.
- What is trioctyl trimellitate?
- The compound is obtained from trimellitic anhydride and 2-ethylhexanol in an acid catalyzed esterification process. Due to its high temperature resistance, low volatility and harmlessness to health, trioctyl trimellitate is suitable as a plasticizer for special applications and mainly replaces phthalates there.
- Is trioctyl trimellitate combustible?
- Trioctyl trimellitate (TOTM) is a plasticizer with high stability. The connection is basically combustible, but difficult to ignite and not explosive. When trioctyl trimellitate is burned and thermally decomposed, acrid fumes and noxious gases such as carbon monoxide are released.
- What is the refractive index of trioctyl trimellitate?
- The refractive index of trioctyl trimellitate (TOTM) is 1.4485 (25°C). TOTM is used as a heat-endurant and long-lasting plasticizer for polyvinyl chloride, usually for preparing Grade 105°C electrical cable and other heat-resisting plastic products. It possesses both advantages being used as a plasticizer for polyesters and for general purposes.
- How does trioctyl trimellitate react with oxidizing agents?
- Trioctyl trimellitate (TOTM) reacts with strong oxidizing agents and acids. This can lead to reactions with intense heat development, so that the reaction products ignite. Explosive hydrogen, among other things, can form in contact with alkali metals and alkali hydrides.
- Is trioctyltrimellitate hazardous to water?
- Trioctyl trimellitate is considered to be slightly hazardous to water and should not be released into soil, water bodies or waste water. Trioctyltrimellitate (TOTM) offers high resistance to heat, making it a versatile plasticizer for durable and heat-resistant plastics in a wide range of applications.
