• DIDP
    is produced by esterifying Iso-Decanol and Phthalic Anhydride.DIDP's low volatility and superior low-temperature characteristic make it applicable to various processes.Its excellent electric resistivity and high temperature characteristic make it widely applied to the manufacturing of PVC cable especially cable of high temperature level.To compare with DEHP in PVC processing, DIDP's gelation temperature required is 5-10℃ higher than that of DEHP.Therefore, some adjustment in processing conditions must be made.The method of adjustment varies according to the production process adoped and equipment used.Generally speaking,most DIDP are added with antioxidant Bisphenol A to increase heat resistance,control oxidation and prevent discoloration,decomposition and evaporation.
