Trioctyl trimellitate (TOTM) transport
High-performance plasticizer, general cargo, in bulk.
TRESAL (Transportes Especializados del Altiplano, S. de R. L. de C. V.) transports trioctyl trimellitate (TOTM) in bulk in stainless steel tank trucks, with nationwide coverage from its bases in Cuautitlán Izcalli —part of the Greater Mexico City area— and San Luis Potosí. Every shipment travels in a dedicated unit with the traceability we give every shipment.
What is trioctyl trimellitate (TOTM) and what is it used for?
Trioctyl trimellitate (TOTM) is a high-performance plasticizer for PVC. Its trimellitate structure gives it low volatility, high thermal stability and low migration. Many grades comply with standards such as USP Class VI, FDA and REACH, making it suitable for medical and demanding applications.
Uses and sectors of TOTM
TOTM is chosen when plasticizer performance is critical:
- Medical PVC (tubing, bags and devices) in USP Class VI grades.
- High-temperature cables and insulation (105 °C and above).
- Automotive interiors and long-life coatings.
- Applications requiring low migration and low volatility.
It is the high-performance plasticizer alternative to dioctyl phthalate (DOP), which is more general-purpose.
How is TOTM safely transported in bulk?
TOTM is moved in a stainless steel tank truck, in a dedicated unit, without consolidating third-party freight, to preserve its purity and prevent cross-contamination. TRESAL delivers door to door. See our bulk chemical transport services and 304 vs. 316L stainless steel options.
Quality and cleaning between loads
Between loads we wash tank trucks with high-pressure hot water in a single pass, documenting every wash, to prevent cross-contamination and preserve product purity. We operate under ISO 9001:2015 and with criteria equivalent to the international tank-cleaning standard (EFTCO). More detail on our tank truck washing service.
Frequently asked questions
Why is TOTM used in medical PVC?
Because of its low migration, low volatility and thermal stability, and because many grades comply with USP Class VI, FDA and REACH, making it suitable for medical devices and long-life applications.
Which tank is used to transport TOTM in bulk?
A stainless steel tank truck, in a dedicated unit and with documented washing between shipments.
