Trioctyl Trimellitate(TOTM)

Trioctyl Trimellitate TOTM is a heatproof and durable plasticizer, and concurrently, it bears the advantages of polyester plasticizer and monomer plasticizer. It has excellent intermiscibility, processability, low temperature resistance and electrical performance, mainly used for making heatproof electric wire as well as plates, sheets, sealing gasket, and so on. TOTM is also applied to vinyl chloride copolymer, nitrocellulose, ethyl cellulose and polymethyl methacrylate etc.
