Professional R&D and excellent quality plasticizer chemicals

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 most important features of MONOPLEX DOS low volatility, high plasticizing efficiency, excellent resistance to extraction by water, soaps, and detergents, and excellent flexibility at low 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]

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).

Dioctyl sebacate(DOS) is an excellent cold-resistant plasticizer, with high plasticizing efficiency, high stability and low volatility Except good cold-resistance,suitable for PVC, EVC, polystyrene and synthetic rubber resins
