Trioctyl trimellitate 99 3319-31-1 - Sigma-Aldrich
Trioctyl trimellitate (TOTM) is a flammable plasticizer used to improve the flexibility and durability of poly (vinyl chloride) (PVC). [ 1] [ 2] Application TOTM can plasticize PVC to form a nanocomposite with multi-walled carbon nanotube which can be potentially used for anti-static applications.

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.

Analysis of medical devices (MDs) The results of the GC-MS analyses of MDs in PVC are presented in Table 1.Trioctyl trimellitate (TOTM) was the predominantly detected plasticizer in multi-access infusion sets (35% or g of TOTM/100 g of PVC), extension tubes (30% or g of TOTM/100 g of PVC) and epidural infusion sets (35% or g of TOTM/100 g of PVC).
Sensitive monitoring of the main metabolites of tri-(2
Tri-(2-ethylhexyl) trimellitate (TOTM or TEHTM) is a substitute for the plasticizer di-(2-ethylhexyl) phthalate (DEHP). Here, a fast and sensitive UHPLC-MS/MS method is presented enabling the simultaneous quantification of the six main TOTM metabolites in urine. These include the primary metabolites
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
- What is trioctyl trimellitate (TOTM)?
- Quality guaranteed, find your speciality chemicals with ease. 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.
- Is trioctyl trimellitate toxic?
- Trioctyl trimellitate (TOTM) is not considered a hazardous compound under the GHS classification. The substance is non-toxic due to its high stability, low volatility and insolubility in water. Even swallowing the compound does not cause any serious damage to health.
- Is trioctyl trimellitate soluble in water?
- Trioctyl trimellitate (TOTM) is a clear, yellowish liquid with an oily consistency. The compound is practically insoluble in water, slightly soluble in the organic solvents chloroform and methanol. Trioctyl trimellitate is hardly volatile and can therefore also be used in sensitive areas of application.
- 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.
- 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.
- What can TOTM be used for?
- Such applications can include vinyl automotive interior or molded parts, dishwasher gaskets, seals, and telephone wire. A stabilizer can be added to TOTM, making it useful in electrical or cable & wire applications. TOTM also works well in blends with other plasticizers with low-volatility including DUP or DOTP.
