This report discusses work directed toward preparation of fuel resistant hose that is serviceabe at temperatures as low as -70 F. The bulk of the report describes compounding studies which attempted to provide a balance of the properties suitable for Arctic fuel hose. A description is also provided of the fabrication of large lengths of collapsible and suction type hoses. It was found that the polymer, PNR-LT, a modified phosphonitrilic fluoroelastomer, could be compounded to permit production of Arctic fuel hoses which possess good low temperature flexibility. The hoses possessed good dimensional stability and physical strength, but tensile and tear strengths on samples from the hoses were lower than desired. (Author)
