Abstract
A composition that includes a fuel and a perfluoropolyether (PFPE) is disclosed. The composition may be used as a flare composition in a countermeasure device. Countermeasure devices including the flare composition are also disclosed, as are methods of forming grains of the countermeasure device.
Claims24
A composition, comprising:
- a fuel;
- a perfluoropolyether (PFPE) having a chemical structure of HO(CH2CH2O)nCH2CF2O (CF2CF2O)p(CF2O)qCF2CH2(OCH2CH2)nOH and a fluorine content of about 57%, where n is an integer between 0 and 10, p is an integer between 0 and 50, and q is an integer between 0 and 50;
- and
- a curative.
