  • Process for the manufacture of high performance gun propellants
    Patent number: 6171530
    Abstract: A process for manufacturing a high performance gun propellant containing an energetic thermoplastic elastomeric binder and a high-energy oxidizer is disclosed. The process includes preparing or obtaining a molding powder of the high-energy oxidizer particles coated with the energetic thermoplastic elastomeric binder and extruding the molding powder into the desired gun propellant configuration. The high-energy oxidizer has a concentration in the range from 70% to 85%, by weight, and the energetic thermoplastic elastomeric binder has a concentration in the range from 15% to 30%, by weight. The molding powder has a particle size in the range from 200&mgr; to 2000&mgr;. Typical thermoplastic elastomeric binders include oxetane, oxirane, and nitramine backbone polymers, copolymers, and mixtures thereof. Typical high-energy oxidizers include nitramine oxidizers.
    Type: Grant
    Filed: February 24, 1998
    Date of Patent: January 9, 2001
    Assignee: Cordant Technologies Inc.
    Inventors: Andrew C. Haaland, Paul C. Braithwaite, James A. Hartwell, Val D. Lott, Michael T. Rose
  • Process for the manufacture of high performance gun propellants
    Patent number: 5759458
    Abstract: A process for manufacturing a high performance gun propellant containing an energetic thermoplastic elastomeric binder and a high-energy oxidizer is disclosed. The process includes preparing or obtaining a molding powder of the high-energy oxidizer particles coated with the energetic thermo-plastic elastomeric binder and extruding the molding powder into the desired gun propellant configuration. The high-energy oxidizer has a concentration in the range from 70% to 85%, by weight, and the energetic thermoplastic elastomeric binder has a concentration in the range from 15% to 30%, by weight. The molding powder has a particle size in the range from 200 .mu. to 2000 .mu.. Typical thermoplastic elastomeric binders include oxetane, oxirane, and nitramine backbone polymers, copolymers, and mixtures thereof. Typical high-energy oxidizers include nitramine oxidizers.
