1. Product Description
【Dioctyl Terephthalate】CAS No 6422-86-2 Also known as DOTP and Bis(2-ethylhexyl) terephthalate is an ester of terephthalate, a colorless to light yellow transparent liquid. Manufacturers or suppliers in China use DOTP as an excellent main plasticizer for polyvinyl chloride (PVC) plastics. Like tributyl citrate (TBC), Dioctyl Terephthalate is an environmentally friendly plasticizer. Furthermore, dioctyl terephthalate factories use terephthalic acid and octanol in the presence of a catalyst to produce it.

4. Application & Advantages
Dioctyl Terephthalate is an excellent main plasticizer for polyvinyl chloride (PVC) plastics. It has the advantages of heat resistance, cold resistance, low volatilization, extraction resistance, softness and good electrical insulation properties. Because of its low volatility, the use of DOTP can fully meet the temperature resistance requirements of wires and cables. So factories widely use it in 70°C resistant cable materials and other various PVC soft products. In addition, manufacturers also use dioctyl terephthalate in the production of artificial leather films. Furthermore, DOTP has excellent compatibility and we can also use it as a plasticizer for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc. Moreover, people can also use dioctyl terephthalate as a plasticizer for synthetic rubber, a paint additive, a lubricant for precision instruments, a lubricant additive, and a softener for paper.
