Dioctyl sebvacate(DOS) is colourless,transparent oily liquid,b.p.377ºC,viscosity 25 c.p.(25ºC), refractive index 1.449~1.451(25ºC)
DOS is one of a very unique, limited group of plasticizers, which impart both excellent low temperature flexibility and reasonably good volatility resistance. In addition, Plasthall DOS has good extraction resistance in distilled and soapy water solutions. Plasthall DOS finds utility in applications requiring excellent low temperature properties but greater extraction resistance than Plasthall DOZ can offer

Product Performance:
DOS plasticizer is a superior cold-resisting plasticizer,it has good plasticizing effect and
better heat endurance,light-resisting and electrical properties. It is chiefly used in processing polyvinl chloride and its copolymer,cellulosic resins and synthetic rubbers,etc..It is usually mixed with phthalic esters in use to minimize its migration rate.
DOS has been applied to vinyl-chloride co-polymers, cellulose, CDDP-ms and synthetic rubber, especially suitable to product hardy wire and cable material, artificial leather, thin film, panel and sheet, etc. It has been used to mix with phthalates plasticizer, and to be low-temperature plasticizer for synthesized rubber. In addition, it has been used as the lubricant of the jet engine. It has been used to the system of solid propellant to improve the mechanical properties, to decrease Tg and increase the percentage elongation of solid propellant at low temperature. Also, it can decrease the viscosity of propellant paste to increase the fluidity and flow leveling with good processing property. The dosage is 10%~40% weight to the binder.
Applications:
· DOS is an excellent cold-resistant plasticizer ,with high plasticizing efficiency, high stability and low volatility. Except good cold-resistance ,it also has good heat-resistance, light-resistance, electric and insulation, suitable for PVC,EVC,polystyrene and synthetic rubber resins.
· Especially suitable for the production of cold-resistant wire,cable material,luxury food,meat plastic wrap,artificial leather, thin film,conveyer belt,board,sheet,etc. Usually be used with PA esters
· As the low-temperature plasticizer for synthetic rubbers, DOS has no effect on the vulcanization of rubber
