Professional R&D and excellent quality plasticizer chemicals

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]

1) In this way, dioctyl sebacate is one of the safest currently used industrial plasticizers. Dioctyl sebacate is used for the production of NGP-30-32 and NGP-40-32 (nonflammable); O-45, O-50 and O-55 (frost resistant) soft cable compounds and PL-1m, PLP-2m (shoe plasticate).

MONOPLEX DOS is an ester-type plasticizer, which has been used for many years as a standard in vinyl compounds requiring low temperature flexibility.

The rheology of GAP/HTPB propellant slurry plasticized by A3/DOS was studied. First, single-phase aggregations of GAP and HTPB appear slightly in A3/DOS whereas it is conspicu- ous in DOS, which results from the small surface tension between the GAP/HTPB plasticized by A3/DOS and the weak thermal diffusion of this blend.
