is produced by esterifying 2-Ethylhexanol and Trimellitic Anhydride.TOTM has low volatility and low migration and its eletric resistivity and heat resistance are excellent. The wire and cable to which TOTM is applied in the process can pass USA UL 62 105℃ class.TOTM's migration and water extraction are lower than those of DIDP.To compare with DEHP at the same flexibility,TOTM's cold resistance is lower. With respect to PVC plastisol, under the condition of same flexibility, the viscosity of plastisol made with TOTM base is lower to that made with DIDP.As regards stability,since TOTM plastisol changes less than DEHP,it is considered more stable than DEHP.
