| Properties: | Dioctyl sebacate (DOS) model: XF-169 Product name: Dioctyl sebacate (DOS) Performance and use: This product is a colorless or light yellow transparent oily liquid, with a freezing point of -48 ℃, a boiling point of 256 ℃ (0.67 Kpa), a viscosity of 25mPa. s (20 ℃), a refractive index of 1.449-1.451 (25 ℃), and is soluble in organic solvents such as hydrocarbons, alcohols, ketones, esters, chlorinated hydrocarbons, and insoluble in diols and water. The solubility of water in this product is 0.15% (20 ℃). It is an excellent cold resistant plasticizer for polyvinyl chloride, with high plasticizing efficiency and low volatility. Therefore, in addition to excellent low-temperature cold resistance, it also has good heat resistance and can be used at higher temperatures. This product has good weather resistance and excellent electrical insulation performance. It is often used in combination with phthalates and is particularly suitable for cold resistant wire and cable materials, artificial leather, films, sheets, and other products. This product is non-toxic and can be used as a food packaging material. In addition to polyvinyl chloride products, it can also be used as a low-temperature plasticizer for various synthetic rubbers, as well as a cold resistant plasticizer for resins such as nitrocellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, and vinyl chloride copolymers. Used as lubricating oil for jet engines.
