Trioctyl Trumelliate (TOTM)

Trioctyl Trimellitate (TOTM) is a high-performance plasticizer widely used to improve the flexibility, durability, and processing efficiency of polymer systems. Known for its low volatility, excellent heat resistance, and outstanding permanence, TOTM is especially suited for demanding polyvinyl chloride (PVC) applications that require long service life. It is commonly applied in wire and cable insulation, automotive interiors, medical devices, flooring, and high-temperature resistant vinyl products, where it enhances softness, flexibility, and long-term stability.

Beyond PVC, TOTM is utilized in adhesives, sealants, coatings, and specialty elastomers, where its strong resistance to extraction, migration, and weathering ensures reliable performance. Its ability to maintain plasticizing properties under heat and stress makes it a preferred choice in electrical, construction, and automotive industries, as well as in applications that require low-fogging, long-lasting, and cleaner plasticizers. With its combination of performance, regulatory advantages, and broad versatility, trioctyl trimellitate remains a critical material in industries ranging from healthcare and electronics to specialty chemical manufacturing.
