| Dioctyl sebacate, also known as di-2-ethylhexyl sebacate, or DOS, is prepared by esterification of sebacic acid and 2-ethylhexyl alcohol. Suitable for polyvinyl chloride, vinyl chloride copolymer, nitrate cellulose, ethyl cellulose and synthetic rubber. Its high plasticizing efficiency, low volatility, not only has excellent cold resistance, but also has good heat resistance, light resistance and electrical insulation, and heating has good lubricity, so that the product appearance, feel good, especially suitable for the production of cold-resistant wire and cable materials, artificial leather, film, sheet, sheet and so on. | |||||||||
