TOTM 耐热和耐久性增塑剂，适用于聚氯乙烯、氯乙烯共聚物、硝酯纤维素、聚甲基丙烯酸甲酯等多种树脂。本品在挥发、耐水抽出、耐迁移、耐低温和电性能等方面性能良好，耐久性与聚合型增塑剂相媲美，而增塑效率和加工性能与邻二甲酸酯类增塑剂相近，同时具有单体型和聚合型增塑剂的一些特点。主要用于耐热电缆料（105℃级）、板材、片材、密封垫等要求耐热和耐久的制品。

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 (105℃class), planks, sheets and seals that have heat-resistance and durability requirements.
