Product Description of Dioctyl sebacate CAS#122-62-3
Dioctyl Sebacate (DOS), also known as Bis(2-ethylhexyl) Sebacate, is an ester-based plasticizer manufactured by reacting sebacic acid with 2-ethylhexanol. It offers excellent compatibility with PVC, vinyl chloride copolymers, nitrocellulose, ethyl cellulose, and various synthetic rubbers.
DOS is characterized by its high plasticizing efficiency, low volatility, and outstanding flexibility at low temperatures. It also provides good thermal stability, light resistance, electrical insulation, and lubrication during processing. These properties contribute to improved processing performance as well as a smooth appearance and pleasant feel in the final products.
With its excellent low-temperature performance, Dioctyl Sebacate is widely used in cold-resistant wire and cable compounds, artificial leather, plastic films, sheets, plates, and other flexible PVC applications. It is particularly suitable for products that require good flexibility and durability under low-temperature conditions.

Product Application of Dioctyl sebacate CAS#122-62-3
Dioctyl Sebacate (DOS) is a high-performance plasticizer particularly valued for applications requiring excellent flexibility at low temperatures. It can also be used in the preparation of synthetic lubricants for aviation and jet engine applications. DOS demonstrates good compatibility with PVC, vinyl chloride copolymers, nitrocellulose, ethyl cellulose, and synthetic rubber.
With its high plasticizing efficiency and low volatility, DOS provides excellent low-temperature flexibility while maintaining good thermal stability, light resistance, and electrical insulation performance. Its effective lubricating properties during thermal processing can also contribute to a smoother surface and improved feel of the finished material.
Due to its outstanding cold-weather performance, Dioctyl Sebacate is commonly used in cold-resistant wire and cable compounds, artificial leather, plastic films, sheets, plates, and other flexible polymer products.
