Professional R&D and excellent quality plasticizer chemicals

Dioctyl Sebacate (DOS) is used as a plasticizer for PVC, nitrocelluloses, styrene resins, and synthetic rubbers where low temperature performance is required. DOS is also compliant with FDA CFR 21 for food contact materials. Dioctyl Sebacate can also be used in lubricants to allow more mobility at lower temperatures.

Dioctyl sebacate (also di (2-ethylhexyl) sebacate, commonly abbreviated as DOS, DEHS, and BEHS) is an organic compound which is the diester of sebacic acid and 2-ethylhexanol . It is an oily colorless liquid and is used as a plasticizer, including in the explosive C4. [3]

In 45 collocated PM2.5 tests conducted at three U.S. cities, regression of liquid DOS versus liquid DOW 704 produced slopes, intercepts, and R2 values of 0.995, -0.006 ug/m3, and 0.999, respectively. As a result of these tests, DOS oil has been approved by EPA as a substitute for the ' DOW 704 oil.

Di Octyl 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.

Cold Resistant Plasticizer DOS (dioctyl Sebacate)The common varieties of cold resistant plasticizers are DOS, dioctyl adipate and diisobutyl nylon.Of these varieties, diisobutyl nylon acid is the most volatile, dioctyl adipate is High Quality Plasticizer Dioctyl Sebacate Plastifiyan Hot Dioctyl sebacate (DOS) is the best plasticizer for PVC polymers. DOS is remarkable for its lowest volatility
