Dioctyl Sebacate is light yellow or colorless transparent liquid. The color (APHA) is less than 40. Freezing point -40°C, boiling point 377°C (0.1MPa), 256°C (0.67kPa). The relative density is 0.912 (25°C). Refractive index 1.449~1.451(25℃). The ignition point is 257℃~263℃. Viscosity 25mPa•s (25℃). Insoluble in water, soluble in hydrocarbons, alcohols, ketones, esters, chlorinated hydrocarbons, ethers and other organic solvents. Good compatibility with resins such as polyvinyl chloride, nitrocellulose, ethyl cellulose and rubber such as neoprene. . It has high plasticizing efficiency and low volatility, not only has excellent cold resistance, but also has good heat resistance, light resistance and electrical insulation, and has good lubricity when heated, so that the appearance and feel of the product are good, especially It is suitable for making cold-resistant wire and cable materials, artificial leather, films, plates, sheets, etc. U.S. FDA approves dioctyl sebacate plasticized plastic film for food packaging materials.


Dioctyl sebacate is one of the excellent varieties of cold-resistant plasticizers. It is suitable for polymer products such as polyvinyl chloride, vinyl chloride copolymer, cellulose resin and synthetic rubber. It has high plasticizing efficiency, low volatility, and cold resistance. , heat resistance, good light resistance and certain electrical insulation characteristics, especially suitable for use in cold-resistant wire and cable, artificial leather, plate, sheet, film and other products. Due to its high mobility, easy to be extracted by hydrocarbon solvents, not water resistant and limited compatibility with the base resin, it is often used as an auxiliary plasticizer and a phthalic acid main plasticizer. It is used as a low temperature plasticizer and is also used in synthetic lubricating oils for steam jet engines.

Chemical Properties

Colorless or pale yellow oily liquid. Insoluble in water, soluble in ethanol, acetone, benzene and other organic solvents. Compatible with ethyl cellulose, polystyrene, polyethylene, polyvinyl chloride, etc., and partially compatible with cellulose acetate and cellulose acetate-butyrate.
