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.

Bis (2-ethylhexyl) sebacate, or dioctyl sebacate (DOS), is a non-polar plasticizer that has two ester groups that bond with cationic compounds. It is mainly used in the formation of thin plasticized polyvinyl chloride (PVC) based membranes. 1 Application
