Document Type and Number:
Japanese Patent JP2010526010
Kind Code:
A
Abstract:
The present invention provides pyrotechnic gas generator compounds and a method of obtaining them. Said compounds have a composition which comprises: an oxidizing charge which comprises at least one inorganic perchlorate and which does not comprise a chlorine scavenger; and a crosslinked, oxygen-containing hydrocarbon binder obtained by crosslinking an elastomer in the presence of at least one crosslinking agent and at least one oxygen-containing plasticizer for said elastomer; said elastomer having a molecular weight of more than 200 000 and being preferably selected from polyesters and polyacrylates; said at least one oxygen-containing plasticizer being composed of a plasticizer of which the molecular weight is greater than 350 g/mol and the oxygen balance equal to or greater than −230 %, of a mixture of such plasticizers with one another or of a mixture of at least one such plasticizer with at least one other oxygen-containing plasticizer. Said compounds can be obtained continuously by extrusion.
