Product profile
Optafleks TOTM is an organic compound, an ester of 2-ethylhexanol and trimellitic acid. It is used mainly in PVC processing and in copolymers.
Chemical identity
- Chemical Structure
- Tris(2-ethylhexyl) trimellitate
- Abbreviation
- TOTM
- CAS No.
- 3319-31-1
- Molecular Weight
- 546
- Formula
- C33H54O6
Application and product selection
Assess long-term heat ageing, mass loss and retention of mechanical properties together. TOTM viscosity may affect processing and mixing conditions. The raw material's flash point is not the continuous service temperature of the finished PVC article; validate temperature ratings through finished-product tests.
- Cable insulation and sheathing with heat-ageing requirements
- Automotive and technical PVC formulations
