Tris(tridecyl) trimellitate

Tris(tridecyl) trimellitate (CAS 94109-09-8, EC 302-446-4) is a trimellitate ester plasticizer derived from trimellitic anhydride and tridecanol, commercially available under trade names including Imex TM 139. It carries no assigned E-code and is identified by the molecular formula C48H84O6.

In plastics processing, it functions as a high-molecular-weight plasticizer in PVC compounds, reducing polymer chain interactions to improve flexibility at elevated temperatures without significant volatility loss. In industrial lubricants and metalworking fluids, its ester structure provides a stable base fluid with good thermal resistance and low evaporation, supporting performance under mechanical stress.

This product is supplied as a viscous liquid and is registered under REACH. It is relevant to the automotive, plastics, and lubricants sectors. Procurement teams should confirm available pack sizes, lot documentation, and supplier-specific technical data sheets directly with the distributor to ensure grade suitability.
