TOTM (Tri Octyl Trimellitate) is a high-performance PVC plasticizer widely used in applications where low volatility, excellent thermal stability and durable flexibility are required. It is scientifically identified as tris(2-ethylhexyl) trimellitate with CAS Number 3319-31-1, molecular formula C33H54O6.
TOTM is a primary plasticizer for polyvinyl chloride (PVC) and PVC copolymers, especially in wire & cable insulation and other temperature-critical polymer formulations.

TOTM offers several performance advantages in thermoplastic formulations:
Low volatility: Minimal plasticizer loss at elevated temperatures.
Excellent heat resistance: Suitable for high-temperature polymer applications.
Good compatibility with PVC and copolymers.
Enhanced flexibility and durability in finished products.
Resistance to extraction and migration compared to general plasticizers.
TOTM is ideal for applications that require long-term flexibility under thermal stress and low migration, such as:
PVC wire and cable insulation
Automotive interior components
Electrical cables and connectors
Flexible PVC compounds
Gaskets, hoses and industrial PVC products
Typical dosing levels are formulated with compound designers based on polymer type and end-use requirements.
