Abstract
Double-base propellants are inhibited with polymeric material to restrict the burning surface. The energetic plasticizer may migrate out of the propellant into the inhibitor. This may then cause the inhibitor to deteriorate. Thus, the measurement of the amount of energetic plasticizer that migrates into the inhibitors is important. Sorption measurements are done using a 'sandwich' test. The data obtained are used in an empirical formula to calculate the maximum amount of energetic plasticizer that will be absorbed by a particular polymer. The validity of the formula is confirmed.
