A process for preparing phase stabilized ammonium nitrate comprises the following steps. A solution of ammonium nitrate ( ), a phase stabilizer ( ), and an inert liquid ( ) is prepared. The solution is atomized to form a stream of droplets. The droplets ( ) are freeze dried to form phase stabilized ammonium nitrate.

Process for preparing phase-stabilized ammonium nitrate

A gas generating material ( ) comprises an oxidizer, a fuel, and a binder composition. The binder composition includes a polystyrene based thermoplastic block copolymer and a thermoplastic modifier. The thermoplastic modifier is miscible with the polystyrene based thermoplastic block copolymer and has a glass transition temperature greater than about 170&deg; C.

Binder for a gas generating material

An apparatus ( ) for helping to protect a vehicle occupant includes an inflatable vehicle occupant protection device ( ) and a inflator ( ) for providing inflation fluid to inflate the vehicle occupant protection device ( ). A non-azide gas generating material is in the inflator ( ). The non-azide gas generating material when combusted produces inflation fluid, which comprises carbon monoxide (CO) and nitrogen oxides (NO ). A catalyst system, which contacts the inflation fluid, is also in the inflator. The catalyst system is reactive with the carbon monoxide (CO) and nitrogen oxides (NO ) in the inflation fluid. The catalyst system comprises a zeolite and a catalytic material. The catalytic material is supported by the zeolite.
