Product Details

Products Description of Dioctyl terephthalate CAS#6422-86-2

Dioctyl terephthalate (DOTP) is a high-performance main plasticizer for polyvinyl chloride (PVC) plastics. Compared with the commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, low volatility, anti-extraction, flexibility and good electrical insulation performance. It shows excellent durability, soap water resistance and low-temperature flexibility in the products. Due to its low volatility, the use of DOTP can fully meet the temperature resistance grade requirements of wires and cables, and can be widely used in 70℃ resistant cable materials (International Electrotechnical Commission IEC standard) and various other PVC soft products.

Product Application of Dioctyl terephthalate CAS#6422-86-2

In addition to being widely used as a plasticizer for cable materials and PVC, DOTP can also be used in the production of artificial leather films. In addition, DOTP has excellent compatibility and can also be used as a plasticizer for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, cellulose nitrate, etc. It can also be used as a plasticizer for synthetic rubber, a coating additive, a lubricant for precision instruments, a lubricant additive, and a softener for paper.
