Abstract
The method for producing a propellant powder (TLP) with a layered grain structure starts with a green powder, which is impregnated in a watery emulsion with an energetic plasticizer and a polymeric deterrent. Propellant powders (TLP) can be produced in industrial quantities by avoiding the dangerous direct introduction of a blasting oil. The propellant powders (TLP) produced in this way have similar characteristics and a similar structure as the known propellant powders (TLP).
