What Is DOTP Plasticizer

DOTP plasticizer is one of the types of plasticizer, this product is almost colorless low viscosity liquid. The viscosity is 63mPa.s (25°C), 5mPa.s (100°C), 410mPa.s (0°C). Freezing point -48℃. Boiling point is 383℃(0.1)MPa.s(0℃). The ignition point is 399℃. Scientific name: Dioctyl terephthalate.


Dioctyl terephthalate (DOTP) is an excellent main plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, hard to volatilize, resistance to extraction, flexibility and electrical insulation properties, and shows excellent durability in products. Resistance to soapy water and low temperature flexibility. Because of its low volatility, the use of DOTP can fully meet the temperature resistance requirements of wires and cables, and can be widely used in 70°C-resistant cable materials (IEC standard of the International Electrotechnical Commission) and various other soft PVC products. In addition to a large number of plasticizers for cable materials and PVC, DOTP can also be used for the production of artificial leather films. In addition, it has excellent compatibility and can also be used as a plasticizer for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc. It can also be used as a plasticizer for synthetic rubber, paint additives, precision instrument lubricants, lubricant additives, and as a softener for paper.
