Heat-resistant potassium perchlorateHycar polyacrylic binder propellants, extrudable in small web geometries, were evaluated for application to propellant actuated cartridges to withstand temperatures from -65 to 400 F. Results of measurements of autoignition temperature, amount and nature of gas evolution, and retention of grain configuration showed these propellants to have thermal stability sufficient to meet the 400 F-4 hour high temperature objective. Extensive firings in the M73 cartridge-M3 or M5 initiator system from -65 to 400 F demonstrated the ability of these propellants to survive and function, as designed, in a typical propellant actuated device.
