DOS is a high quality cold-resisting primary plasticizer for PVC and PVC copolymers. It has high plasticizing efficiency and low volatility thus shows great heat resistance as well and it could be applied in high temperature environment. DOS has excellent weather resistance and insulativity.
It is also used as the plasticizer for solid propellants and their cladding layers.

Dioctyl Sebacate is a plasticizer for PVC, and its copolymers, nitrocelluloses, styrene resins and synthetic rubbers where low temperature performance is required. The end applications include anti-frosting cable and PVC linoleum.
DOS can be used in cold-resisting cable and wire sheath materials, artificial leather, plastic film, panel, sheet. DOS is non-toxic, TEFs=1000, there is no symptom of poisoning on experiment rat test for DOS intake thus DOS could be used in food packing materials. It can be also used as the cold-resisting plasticizer for synthetic rubber, nitryl cellulose, ethyl cellulose, polymethyl methacrylate, polystyrene, vinyl chloride copolymer. DOS could be used as lubricating oil for jet engine, too.
