  • Publication number: 20050092407
    Abstract: An explosive composition is provided that includes 85 to about 96 weight percent nitramine, based on the total composition weight, and about 4 to 15 weight percent plasticized binder. At least 80 weight percent of the total composition weight, and more preferably 85 to 96 weight percent of the total composition weight, comprises 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.05,903,11]-dodecane (CL-20) particles having an average particle size not greater than 30 microns as the nitramine. Methods for preparing an explosive from the explosive composition are also provided.

  • Patent number: 6214137
    Abstract: High performance explosive compositions and ordnances using the explosive compositions as an explosive ingredient for high performance, low sensitivity explosive applications are disclosed. The explosive formulation includes CL-20 as an explosive ingredient, and a binder system including cellulose acetate butyrate as a non-energetic binder and bis-dinitropropyl acetal and bis-dinitropropyl formal as an energetic plasticizer. The CL-20 may be present in the explosive formulation in a concentration of from about 85 wt % to about 96 wt %. The formulation is preferably sufficiently pressable and/or extrudable to permit it to be formed into grains suitable for ordnance and similar applications, including use as grenades, land mines, missile warheads, and demolition explosives.

  • Patent number: 5472531
    Abstract: The explosive blasting composition in this invention contains 1 to 40 pert Aluminum powder, 40 to 80 percent Cyclotetramethylene Tetranitramine, 4 to 15 percent Cellulose Acetate Butyrate, 5 to 20 percent of 1:1 mixture of bis 2,2-dinitropropyl acetate and bis 2,2-dinitropropyl formal, and, and 0.25 to 0.75 percent Tri (dioctyl Phosphato) Titanate.The method of making the above composition consists of combining Cyclotetramethylene Tetranitramine, Cellulose Acetate Buterate, 1:1 bis 2,2-dinitropropyl acetate and bis 2,2-dinitropropropyl formal, and tri (dioctyl phosphato) titanate, mixed at an elevated temperature for a period of time. Prior to blowdown, the Aluminum powder is added. to the mix. Mixing continues and blowdown is initiated to remove excess solvents for the purpose of extrusion.

  • Patent number: 4842659
    Abstract: A high energy explosive composition containing 80 to 95 percent HMX having low susceptibility to sympathetic detonation. The composition also contains between 2.9 to 10 percent cellulose acetate butyrate, 10 to 17.1 percent of 1:1 mixture of bis 2,2-dinitropropyl acetate and bis 2,2-dinitropropyl formal, and 0.5 percent tri (dioctyl phosphato) titanate.
