Product Description of Dioctyl sebacate CAS#122-62-3
Dioctyl sebacate, also known as bis(2-ethylhexyl) sebacate (DOS), is produced through the esterification of sebacic acid and 2-ethylhexanol. It is widely compatible with polyvinyl chloride (PVC), vinyl chloride copolymers, nitrocellulose, ethyl cellulose, and synthetic rubber.
The product features high plasticizing efficiency and low volatility, along with excellent cold resistance, good heat resistance, light stability, and electrical insulation properties. In addition, it provides good lubricity during heating, which helps improve both the appearance and tactile quality of finished products.
Dioctyl sebacate is especially suitable for the production of cold-resistant wire and cable materials, artificial leather, films, plates, and sheets.

Product Application of Dioctyl sebacate CAS#122-62-3
Dioctyl sebacate (DOS, CAS 122-62-3), also known as bis(2-ethylhexyl) sebacate (DEHS), is a clear, oily liquid aliphatic diester. It is primarily used as a specialty plasticizer for PVC, synthetic rubbers, and nitrocellulose, imparting exceptional low-temperature flexibility for cold-resistant wires, cables, films, and medical tubing. It also serves as an emollient and solvent in cosmetics and pharmaceuticals, a base stock for synthetic lubricants and hydraulic fluids, and an aerosol generation agent for respiratory research.
