Professional R&D and excellent quality plasticizer chemicals

Consequently, when PVC compositions are plasticized with dicarboxylic acid esters, plasticizer efficiency directly depends on the number of methylene groups in the ester composition and on the infused plasticizer quantity. Dioctyl sebacate (DOS) is the best plasticizer for PVC polymers.

Dioctyl sebacate 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]

DOS (DEHS) Plasticizer Dioctyl sebacate (DOS) is the best plasticizer for PVC polymers. DOS is remarkable for its lowest volatility as compared to other industrial plasticizers - DBS, DOP and DBP (Table1). Get Price Plasticizers: Types, Uses, Classification, Selection
