Abstract:
PROBLEM TO BE SOLVED: To provide an ignition substance which has resistance force to breakage, has a size approximately equal to that of gas generating particles, and has elasticity to have the surface area approximately equal to the surface area of a powdery ignition material. SOLUTION: A foamable ignition composition effective in forming the foaming ignition substance at least partly contains a fluoropolymer bonded oxidizing agent, a plasticizer effective in softening the fluoropolymer bonded oxidizing agent, a metal fuel reacting with the fluoropolymer bonded oxidizing agent, a foaming agent effective in making the foamable ignition composition porous and a crosslinking agent effective for structurally stabilizing the foaming ignition substance and is so constituted as to form the foaming ignition substance when heated up to a prescribed temperature.

Abstract:
PROBLEM TO BE SOLVED: To provide alkali metal perchlorate-containing gas generant compositions which, upon combustion, produce or result in an improved effluent and related methods for generating an inflation gas for use in an inflatable restraint system.SOLUTION: The alkali metal perchlorate-containing gas generant compositions include at least one alkali metal perchlorate present with a mean particle size in excess of 100 micrometers. Such alkali metal perchlorate-containing gas generant compositions also include or contain a suitable non-azide, organic nitrogen-containing fuel and at least one copper-containing compound selected from the group consisting of basic copper nitrate, cupric oxide, copper diammine dinitrate-ammonium nitrate mixture wherein ammonium nitrate is present in the mixture in a range of about 3 to about 90 wt.%, copper diammine bitetrazole, a copper-nitrate complex resulting from reaction of 5-aminotetrazole with basic copper nitrate and combinations thereof.
Abstract:
Inflator device assemblies containing an expandable fluid effective to provide a gaseous inflation medium also advantageously employ or incorporate a pyrotechnic material such as to augment or enhance at least one fill characteristic of the gaseous inflation medium. The pyrotechnic material is provided on a selected non-gas generant surface within the inflator device. Suitable pyrotechnic compositions may include a binder additive effective to adhere the pyrotechnic composition to a surface within the inflator device.
Abstract:
A method for increasing the burn rate of a gas generant formulation is provided involving the addition of a quantity of at least one transition metal complex of diammonium bitetrazole to the gas generant formulation.
