摘要:
The solvent-free gas generant composition of this invention, comprising an oxidizer and a thermosettable resin, cures in about an hour or less at room temperature and within 5 minutes at 135.degree. F. Void-free and crack-free gas generant grains are formed and cured in an extrusion process in which the temperature may be from about room temperature to about 200.degree. F. The thermosettable resin is at least one of the group consisting of an acrylate-terminated polybutadiene, a hydroxy-terminated polybutadiene/diisocyanate reaction product, an ester of a polybutadiene polycarboxylic acid and an epoxy modified polybutadiene and/or a hydroxyl-terminated polybutadiene, and a styrene/polyester copolymer.

摘要:
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 are provided. Such alkali metal perchlorate-containing gas generant compositions include at least one alkali metal perchlorate present with a mean particle size in excess of 100 microns. 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 weight percent, copper diammine bitetrazole, a copper-nitrate complex resulting from reaction of 5-aminotetrazole with basic copper nitrate and combinations thereof.
摘要:
An inflator that includes a quantity of gas generant housed within a chamber. A liquid including at least one of a fuel soluble in the liquid or an oxidizer soluble in the liquid and a piston are housed within another chamber of the inflator. This chamber is sealed. Upon actuation, movement of the piston hydraulically expels the liquid through an opening in the piston such that the liquid contacts the gas formed by combustion of the gas generant and cools the same. The fuel and/or oxidizer in the liquid can react to form additional gas.
摘要:
Incorporating organophilic clay into hot melt adhesive compositions, particularly those comprising semi-crystalline, thermoplastic polymers, greatly improves the adhesive properties in many respects. Some of these improvements are particularly beneficial to the specific use of hot melt adhesives filled with electrically conductive particles for use as electrically conductive adhesives.
摘要:
Gas generant compositions, such as may be suited for use in inflating automotive inflatable restraint airbag cushions, are provided. Such gas generant compositions generally contain a mixture of guanidine nitrate, ammonium nitrate, and a transition metal ammine nitrate, such as copper diammine dinitrate and preferably also contain one or more ballistic additives.
摘要:
Gas generant compositions and methods of processing are provided which produce or result in a relatively high burning rate and low burning rate pressure exponent, while also desirably providing a high gas output, as compared to normal or typical gas generant formulations such as used in association with vehicle occupant restraint airbag cushions.
摘要:
An ignition enhanced gas generant grain and method of making an ignition enhanced gas generant involving the application of a dry blend igniter composition to a gas generant particle having a wet adhesive surface.
摘要:
Igniter compositions and methods of processing are provided which produce or result in relatively little particulate material, as compared to typical igniter compositions used in association with vehicle occupant restraint airbag cushions.
