this dioctyl sebacate (DOS) is an ester type plasticizer. it has been used for many years as a standard in polyvinyl chloride (pvc) compounds requiring flexibility at low temperatures. it is the typical high quality cold resistance pvc plasticizers with high plasticizing efficiency and low colour distortion.

types and differences of common pvc plasticizers,the most commonly used varieties are dioctyl adipate and dioctyl sebacate. (1) dioctyl adipate (DOA) is a colorless, odorless liquid, non-toxic, soluble in most organic solvents, slightly soluble in ethylene glycol and insoluble in water. the critical plasticizing temperature of DOA for pvc is 12l-125 ℃.
