ABSTRACT:
A solventless method for the preparation and storage of uncured low vulnerability ammunition propellant (LOVA) includes blending from about 60 to 80 weight percent of either HMX or RDX oxidizer having a weight mean diameter from 1.0 to 14 microns with a polyurethane binder. A cure effecting amount of cure catalyst may also be included. These ingredients are blended at a temperature below about 110.degree. F., deaired, and optionally stored at low temperatures at a pre-cured condition, extruded and subsequently cured. The products produced thereby have uniquely low burning rates as well as uniquely low burning rate exponents.
