Abstract
Flexible, self-supporting explosive compositions composed essentially ently of a particulate high explosive RDX, HMX and/or PETN and a high viscosity nitrocellulose binder plasticized with triethyleneglycol dinitrate.
Claims3
A flexible, self-supporting explosive composition of high power and brisance composed essentially entirely of explosive ingredients and consisting essentially of
- a. about from 50 to 90 weight percent of a particulate high explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate and mixtures thereof having an average particle size not exceeding about 25 microns;
- and
- b. about from 10 to 50 weight percent of a binder system consisting essentially of high viscosity nitrocellulose containing about from 12.1 to 12.5 percent nitrogen, and triethyleneglycol dinitrate plasticizer;
- wherein the amount of said nitrocellulose is about from 1 to 8 weight percent of the composition and the weight ratio of said plasticizer to said nitrocellulose is about from 4:1 to 7:1, respectively.
A flexible, self-supporting explosive composition of high power and brisance adapted for use as a flexible sheet explosive, composed essentially entirely of explosive ingredients and consisting essentially of:
- a. about from 50 to 70 weight percent of a particulate high explosive selected from the group consisting of cyclotrimethylenetrinitramine, cyclotetramethylenetetranitramine and pentaerythritol tetranitrate and mixtures thereof having an average particle size not exceeding about 25 microns;
- and
- b. about from 30 to 50 weight percent of a binder system consisting essentially of high viscosity nitrocellulose containing about from 12.1 to 12.5 percent nitrogen, and triethyleneglycol dinitrate plasticizer;
- wherein the amount of said nitrocellulose is about from 4 to 8 weight percent of the composition and the weight ratio of the plasticizer to the nitrocellulose is about from 4:1 to 7:1, respectively.
