Abstract
This substantially water-free method for preparing high density igniter granules involves uniformly coating fuel and oxidizer particulates dispersed in a non-solvent with a thermoplastic elastomer solution to produce coated igniter granules exhibiting substantially uniform size and shape distributions. The coated igniter granules are especially useful for waterless extrusion into igniters for automobile gas generating inflation devices, solid propellant rocket motors, and thrust decoys.
