Abstract : The invention relates to explosives and more particularly to energetic plasticizers for plastic bonded explosives. Bis(2-fluroro-2, 2-dinitroethyl) formal, CH2OCH2CF(NO2)22(FEFO), has the highest density (1.60 g/cc) of any energetic plasticizer currently in use. For energetic materials, density is a critical property since the performance of the material is proportional to the square of its density. Hence, an energetic plasticizer with a significantly higher density than FEFO would offer a definite advantage. Also an energetic plasticizer with a lower melting point than that of FEFO (mp of FEFO is 14 deg C) is preferable especially if the lower melting point is not accompanied by the usual higher volatility. Even with its relatively high melting, FEFO suffers a disadvantage in that it has higher volatility than desired. In addition, FEFO has a limitation in that it does not contain sufficient oxidant (oxygen and fluorine) to combust all carbon and hydrogen to CO2, H2O, and HF. Patent applications. (js)
