CAS 122-62-3

Dioctyl sebacate is an important cold-resistant plasticizer with excellent low-temperature performance, weather resistance, and electrical insulation properties, widely applied in various industrial fields. The following is a detailed introduction to its main application scenarios:

1. Dioctyl sebacate is a key plasticizer for polyvinyl chloride (PVC) and other plastics, particularly suitable for products with high requirements for low-temperature performance, such as cold-resistant PVC products (plastic films and hoses used in winter), medical PVC products (such as IV tubes and blood bags), and food packaging films.
2. In rubber products, DOS is primarily used as a softener and plasticizer, such as in synthetic rubber (nitrile rubber, chloroprene rubber) and rubber seals in the automotive and machinery industries.
3. Dioctyl sebacate is also used in the insulation layers and sheathing materials of wires and cables, such as cold-resistant cables and oil-resistant cables.
4. In some coatings used in low-temperature environments, DOS can be used as a plasticizer to improve the flexibility and crack resistance of the coating film.
5. Adding DOS to adhesives can enhance their low-temperature viscosity and flexibility, ensuring that the adhesive maintains good bonding performance even in low-temperature conditions.
6. Dioctyl sebacate can be used as a component of certain special lubricants, suitable for lubrication requirements in low-temperature conditions.
   In some cosmetics (such as creams and lotions), DOS can be used as an emollient to improve the skin feel and spreadability of the product (must comply with cosmetic raw material safety standards).
