Trioctyl Trimellitate, commonly known as TOTM, with CAS No. 3319-31-1, stands as a premier high-molecular-weight plasticizer. This versatile compound, characterized by its chemical formula C33H54O6, is a transparent to colorless oily liquid distinguished by its mild odor. It is widely recognized for its exceptional performance characteristics, making it indispensable in demanding industrial applications.

One of TOTM's most significant advantages is its outstanding thermal stability and durability. It functions as a heat-resisting and durability-resisting plasticizer, ideally suited for a broad range of resins including PVC, nitro cellulose, and PMMA. Unlike many conventional plasticizers, TOTM exhibits superior resistance to volatility, extraction, and transference, ensuring the longevity and integrity of the end products. Its impressive electrical properties and resistance to both low and high temperatures further underscore its versatility and reliability, especially when compared to alternatives like DOTP, thanks to its high volume resistivity.

The applications of Trioctyl Trimellitate are extensive and critical across various sectors. In the plastics industry, particularly for polyvinyl chloride (PVC), TOTM is the preferred choice for products requiring extreme low volatility and extended service life. This includes, but is not limited to, the manufacture of heat-resistance cable materials, specifically 105°C grade cables, insulating materials, boards, and sealing gaskets. Its low migration properties are also highly valued in automotive interior components and molded parts, as well as in critical items like dishwasher gaskets, seals, and telephone wires, where product integrity over time is paramount. TOTM can also be effectively blended with other general-purpose plasticizers to enhance overall performance and reduce volatility.

Beyond its role in plasticization, TOTM serves as a high-performance synthetic ester base fluid and additive in the lubricants industry. Its unique properties, including high viscosity, oxidative stability, excellent solvency, and superior lubricating characteristics, make it an ideal candidate for high-temperature applications. These include formulations for engine oils, compressor oils, high-temperature chain oils, and various greases. Furthermore, it finds use in specialized areas such as transformer fluids, high-temperature conveyor bearings, textile lubricants, and disk drive components, even meeting HX1 base fluid requirements for specific industrial applications.

The production of Trioctyl Trimellitate involves the acid-catalyzed esterification of trimellitic anhydride with 2-ethylhexanol, ensuring a consistent and high-purity product. Manufacturers adhere to stringent quality controls, typically ensuring an ester content of 99.5% or higher, with low acid and moisture values. This commitment to quality guarantees that the product meets the rigorous demands of various industrial specifications, including environmental protection standards like REACH. Typical packaging options for this essential chemical include 200 kg iron drums, 1000 kg IBC tanks, and 23 metric ton flexitanks, facilitating efficient global distribution and secure handling.

For those seeking a reliable manufacturer and supplier of Trioctyl Trimellitate, it is crucial to partner with entities that prioritize quality, technical expertise, and efficient logistics. When looking to buy TOTM, consider suppliers offering competitive price structures and demonstrated capabilities in fast delivery and consistent product availability. A reputable purchase experience is ensured by selecting suppliers with long-standing experience and a robust supply chain, providing comprehensive support from inquiry to delivery. This ensures access to high-grade TOTM for all your specialized industrial needs, supporting the development of durable and high-performing products across the plastic and lubricant sectors.
