Dioctyl phthalate (DOP) transport
PVC plasticizer, general cargo, in bulk in stainless steel.
TRESAL (Transportes Especializados del Altiplano, S. de R. L. de C. V.) transports dioctyl phthalate (DOP) 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 dioctyl phthalate (DOP) and what is it used for?
Dioctyl phthalate (DOP), also known as di(2-ethylhexyl) phthalate, is a general-purpose plasticizer for PVC. It is an oily, colorless liquid that gives flexibility to polyvinyl chloride products.
Uses and sectors of DOP
DOP is one of the most widely used plasticizers in PVC processing:
- Flexible PVC films, sheets and coatings.
- Cables and electrical insulation.
- Hoses, profiles and PVC footwear.
- Adhesives, sealants and inks.
For demanding applications —high temperature, low migration or medical use— trioctyl trimellitate (TOTM) is the reference high-performance plasticizer.
How is DOP safely transported in bulk?
DOP is moved in a stainless steel tank truck, in a dedicated unit, without consolidating third-party freight, to 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 quality. 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
What is the difference between DOP and TOTM?
DOP is a general-purpose PVC plasticizer; TOTM is a high-performance plasticizer with greater thermal stability and lower migration, used in medical and high-temperature applications.
Which tank is used to transport DOP in bulk?
A stainless steel tank truck, in a dedicated unit and with documented washing between shipments.
