Barrier Films for Mk 12 Mod 2 Cartridge Plug

Abstract

An investigation was conducted for the purpose of selecting a film barrier to minimize permeation of nitroglycerin vapors from M26 propellant into a polyurethane foam cartridge plug. This investigation consisted of a literature survey, polymer selection and screening, and 16 week permeation tests. The results of the study showed fluorinated ethylene propylene (FEP) to provide the best barrier against nitroglycerin vapors, but an interaction between this film and the M26 propellant was detected. The second best barrier was poly (chlorotrifluoroethylene) (CTFE). None of the films tested were found to be affected by the nitroglycerin vapors. Solubility parameter was found to be the most useful predictor of nitroglycerin permeation rates.
