Dioctyl terephthalate USES

1. Dioctyl terephthalate (DOTP) is an excellent main plasticizer for polyvinyl chloride (PVC) plastics.

2. Compared with the currently commonly used diisooctyl phthalate (DOP), it has the advantages of heat resistance, cold resistance, hard to volatilize, resistance to extraction, flexibility and electrical insulation performance, etc., and shows excellent performance in products Durability, soapy water resistance and low temperature flexibility.

3. 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 ℃ resistant cable materials and other various PVC soft products.

4. In addition to a large number of plasticizers used in 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 plasticizers for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose, etc., as well as plasticizers for synthetic rubber, paint additives, Precision instrument lubricants, lubricant additives, can also be used as softeners for paper.
