Abstract
Abstract A cold moldable explosive composition comprises 85 to 98% by weight of at least one explosive chosen from among octogen, hexogen, pentrite, hexanitrostilbene and triaminotrinitrobenzene, 1.5 to 11% by weight of a thermoplastic binder constituted by a chlorinated and/or fluorinated elastomer, such as copolymer of trifluorochloroethylene and vinylidene fluoride and 0.5 to 4% of a fluorinated plasticizer constituted e.g. by a low molecular weight trifluorochloroethylene polymer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
A cold-mouldable explosive composition comprising from about 85% to 98% by weight of at least one explosive selected from the group consisting of cyclotetramethylenetetranitramine (octogen), cyclotrimethylenetrinitramine (hexogen), triaminotrinitrobenzene (TATB), pentaerythritoltetranitrate (pentrite) and hexanitrostilbene (HNS), from about 1.5 to 11% by weight of a thermoplastic elastomeric binder comprising a copolymer of trifluorochloroethylene and vinylidene fluoride, and from about 0.5 to 4% of a fluorinated plasticizer comprising a trifluorochloroethylene polymer having a molecular weight of from about 500 to 1000.
Claim 2
Dependent Claim
78 words
A cold-mouldable explosive composition comprising from about 85% to 98% by weight of at least one explosive selected from the group consisting of cyclotetramethylenetetranitramine (octogen), cyclotrimethylenetrinitramine (hexogen), triaminotrinitrobenzene (TATB), pentaerythritoltetranitrate (pentrite) and hexanitrostilbene (HNS), from about 1.5 to 11% by weight of a thermoplastic elastomeric binder comprising a copolymer of trifluorochloroethylene and vinylidene fluoride, and from about 0.5 to 4% of a fluorinated plasticizer comprising a trifluorochloroethylene polymer having a molecular weight of from about 500 to 1000.
