Plasticizer TOTM 500ml Sample

TOTM stands for Trioctyl Trimellitate, a trimellitate ester plasticizer. It is a high-performance, high-molecular-weight, non-phthalate plasticizer, valued for its excellent permanence, heat resistance, and low volatility. Because of these traits, TOTM is often used in medical, electrical, and high-temperature PVC applications where migration control and long service life are critical.

Full Name: Trioctyl Trimellitate

Molecular Formula: C₃₃H₅₄O₆

Appearance: Clear, oily, colorless to pale yellow liquid

Key Features

Very low volatility and migration → excellent permanence

High thermal stability and resistance to extraction (oil, detergent, water)

Provides good electrical insulation properties

Maintains flexibility over long service life

Ideal for medical-grade and heat-resistant PVC

Slightly lower plasticizing efficiency than DOP/DOTP (needs higher dosage to achieve same softness)

Applications

Medical devices: blood bags, IV tubing, catheters (TOTM is one of the safest choices due to low migration)

Electrical wires and cables requiring heat resistance and low migration

Automotive interiors exposed to heat/UV aging

High-performance PVC films and sheets

Applications requiring sterilization resistance (steam or gamma sterilization in healthcare)
