Dioctyl sebacate (DOS)

It is a typical cold-resistant plasticizer, suitable for polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, polymethyl methacrylate, nitrocellulose, ethyl cellulose and synthetic rubber. Its plasticizing efficiency is high, 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 product appearance, feel good, especially Suitable for the production of cold-resistant wire and cable materials, artificial leather, film and adhesive, etc. However, the product has a large mobility, is easily extracted by hydrocarbons, and its water resistance is not ideal. It is often used with phthalate esters.

Molecular formula: C26H50O4 Melting point:-55 ℃
Density: 0.918g/cm3 Boiling point: 442 ℃
Refractive index: 1.455(20 ℃) Flash point: 198.41 ℃
Appearance: Colorless or yellowish oily liquid Solubility: 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.
