NASA Develops New FireRetardant Coating Material
The National Aeronautics and Space Administration has developed a foamed ceramic material which effectively insulates enclosed objects at temperatures up to 3000° F. Described in NASA Tech Brief No. 65-10058, an aluminum phosphate mixture provides good thermal insulation, mechanical support and vibrational shielding.
Goddard Space Flight Center, Greenbelt, Md., which developed the process, reported the new material successfully passed rigorous tests for density, thennal shock, thermal conductivity, water solubility, machinability, adherence and colorability. Suggested applications for the new material include home and factory insulation, building material, furnace insulation, steampipe insulation, fireproof acoustic tile, thermally insulated containers and fire protection barriers.
