Abstract (en)
The propellant comprises a binder, a nitratoethylnitroamine softener, preferably butyl nitratoethylnitroamine (Butyl NENA) and an oxidizer, which is free from heavy metals. The binder is a mixture of inert and energetic cellulose derivatives, which is present in 5-30 wt.%, particularly 10-25 wt.% of the mixture. The inert cellulose derivative is a derivative of acetate butyrate and energetic cellulose is a derivative of nitrocellulose.
Abstract (de)
Ein extrudiertes Treibmittel für Automobilsicherheitssysteme beinhaltet einen Binder, einen Weichmacher aus der Klasse der Nitratoethylnitroamine und einen Oxidator, welcher frei von Schwermetallen ist. Besonders bevorzugt ist Butyl-Nitratoethylnitroamin als Weichmacher. Vorzugsweise liegen im Treibmittel energetische Cellulosederivate als Binderkomponenten vor.
