Composition for single-base propelling powder for ammunition and ammunition provided with such composition

Abstract

The present invention relates to a composition for single-base propelling powder for ammunition consisting of nitrocellulose as an explosive base, an inert plasticizer component, at least one nitrocellulose stabilizer component, and optionally a flash-reducer component and traces of one or more solvents and water. The aforementioned inert plasticizing component is dibutyl sebacate (DBS). Preferably, the dibutyl sebacate is present with a content between 2% and 7% by weight.
