Product Description

Dioctyl terephthalate/DOTP

Chemical formula: C24H38O4 CAS No: 4654-26-6

Product Description

 

Dioctyl terephthalate is an almost colorless liquid with low viscosity, offering a smooth and seamless flow. Its viscosity sits at 63 mPa.s at 25ºC, reducing to 5 mPa.s when warmed to 100ºC, and significantly increasing to 410 mPa.s when chilled to 0ºC. The freezing point is a chilly -48ºC, while the boiling point reaches an impressive 383ºCat (0.1) MPa.s at 0ºC. Its ignition point is 399ºC, with a refractive index of 1.4887 and minimal water-solubility of 0.4% at 20ºC.

Applications:

DOTP plasticizer stands as an excellent primary choice for PVC plastics. In comparison to DOP, it provides superior heat resistance, enhanced anti-freezing properties, reduced volatility, and improved flexibility. Thanks to its low volatility, it's perfect for manufacturing wires and cables that operate effectively in low temperatures, and it is widely applied in 70 ºC-resistant cables, adhering to the standards of the International Electrotechnical Commission, among various soft PVC products. Additionally, DOTP is ideal for use in leatherette, film, and as a plasticizer for PE alcohol butyral, acrylonitrile-butadiene rubber, cellulose nitrate, and synthetic rubber. It serves as an excellent coating additive, lubricant for precision instruments, lubricant additive, and paper softener. paper.
