PLASTIC EXPLOSIVE COMPOSITION Russian patent published in 2018 - IPC C06B25/32 C06B45/06 

FIELD: blasting operations.

SUBSTANCE: invention relates to an explosive composition having plastic properties intended for the production of thin-layer charges of various geometric shapes for various purposes, in particular thin-layered plates and tapes. Explosive composition contains a blasting explosive – pentaerythritol tetranitrate and a polymer binder from a mixture of high molecular weight and low molecular weight polyisobutylenes in a ratio of 2:1, respectively, at a ratio of components, % by weight: a mixture of polyisobutylenes from 11 to 13, the rest – pentaerythritol tetranitrate.

EFFECT: plastic explosive composition is intended for the production of thin tapes with the possibility of reducing the specific impulse created by the belts during blasting, with stable explosive characteristics during their long-term storage and with reduced sensitivity to impact for the possibility of perforating belts.
