  • Vegetable oil modified explosive
    Patent number: 5322576
    Abstract: A method of increasing the viscosity, and the resistance to high shear induced crystallization, of a pumpable, shear thickened emulsion explosive, is provided wherein the explosive has been prepared by emulsifying an oxidizer salt phase into a fuel phase, and at least a portion of said fuel phase has been replaced with a vegetable oil. The explosives are particularly suitable for use in up-hole blasting operations because of their high viscosity and resistance to shear induced crystallization of the oxidizer salt.
