Abstract : A study was undertaken to determine the effects of curatives and fillers on the physical properties of polyphosphazene polymers. In general, the addition of compounding ingredients to this type of polymer is difficult on a two-roll rubber-mixing mill. However, calcium oxide and Dow Corning FS1265 fluid functioned as processing aids to facilitate the incorporation of other compounding ingredients. Various peroxides produced crosslinking of the polymer, and Di Cup 40C was found to be the most efficacious. All vulcanizates displayed low-tensile strengths, but certain vulcanizates exhibited good low-temperature flexibility, hydrolytic stability, and resistance to ozone and a variety of fluids.
