Øyvind Hammer Johansen is a notable inventor based in Oslo, Norway. He has made significant contributions to the field of explosive compositions, particularly with his innovative approach to enhancing sensitivity characteristics and processability.

Latest Patents

Johansen holds a patent for a pressable plastic-bound explosive composition. This invention relates to explosive compositions that utilize crystalline explosive crystals of 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX) Type I, either alone or in combination with a smaller percentage of 1,3,5-tetranitro-1,3,5,7-tetrazacyclooctane (HMX). The crystals are coated with a binder system that consists of a polyacrylic elastomer with an added plasticizer. The production process involves a water-slurry method where explosive crystals are washed in water, followed by the addition of the binder solution. After mixing, the solvent is distilled off, and the coated product is isolated through filtering. Johansen's patent is a testament to his innovative thinking in the field of explosives.
