TOTM, a heat-resistant and durable plasticizing agent, is applicable for various kinds of resins such as polyvinyl chloride (PVC), vinyl chloride copolymer, nitrocellulose, polymethyl methacrylate, etc. This product has good performance in volatility, water extraction resistance, migration resistance, low temperature resistance and electrical property. Its durability is comparable to that of poly plasticizing agent; its plasticizing efficiency and processability are similar to that of phthalic acid ester plasticizing agent; meanwhile it has also some characteristics of mono and poly plasticizing agents. It is mainly used for heat-resistant cables (105ºCclass), planks, sheets and seals that have heat-resistance and durability requirements.
