Plasticizer DOS 99.5% Dioctyl sebacate (DOS) CAS 122-62-3

Short Description:

Chemical name: Dioctyl sebacate
Other name: DOS, Bis(2-ethylhexyl) sebacate
CAS #: 122-62-3
Purity: 99.5% min
Molecular formula: C26H50O4
Molecular weight: 426.67
Chemical Properties: Colorless to light yellow liquid. Insoluble in water, soluble in ethanol, ether, benzene and other organic solvents. It can be mixed with ethyl cellulose, polystyrene, polyethylene, polyvinyl chloride, vinyl chloride – vinyl acetate copolymer, etc. Good cold resistance.
Application: DOS is an excellent cold-resistant plasticizer for polyvinyl chloride with high plasticizing efficiency and low volatility. Therefore, in addition to excellent low-temperature and cold-resistant properties, it 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. It is especially suitable for cold-resistant wire and cable materials, artificial leather, films, plates, sheets and other products. This product is non-toxic and can be used for food packaging materials. In addition to polyvinyl chloride products, it can also be used as a low-temperature plasticizer for various synthetic rubbers, as well as for resins such as nitrocellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, and vinyl chloride copolymers. Cold-resistant plasticizer. Used as a lubricant for jet engines.
