A gas generating material (52) for use in a vehicle occupant protection apparatus (10) comprises a particulate oxidizer, a hydroxy terminated polybutadiene, a diisocyanate cross-linking agent, and a plasticizer. The diisocyanate cross-linking agent cross-links the hydroxy terminated polybutadiene to form an elastomeric binder that contains the particulate oxidizer. The ratio of hydroxyl groups of the hydroxy terminated polybutadiene to isocyanate groups of the diisocyanate cross-linking agent is at least about 0.95.
