Approach for Achieving Flame Retardancy While Retaining Physical Properties in a Compatible Polymer Matrix

NASA’s Kennedy Space Center (KSC) seeks to license its Advanced Fire Retardant Materials to industry. KSC’s scientists have developed processes and know-how to impart fire retardancy to common polymers such as nylons, polyesters, and acrylics. NASA developed this technology for use in personnel protective systems for launch pad personnel engaged in hazardous materials (HAZMAT) operations. The invention provides polymer blends containing polyhydroxyamide and one or more flammable polymers. The polymer blends are flame-retardant and have improved durability and heat stability compared to the flammable polymer portion of the blends.
