- Abstract
- The feasibility of preventing propagation from an ignited caseless IMR round to adjacent rounds by the interposition of a thermally stable substrate coated with an intumescent material was examined. Propagation has been prevented in tests on 5.56 mm rounds with 0.5- to 1.0-mil polyimide film as the substrate and a 15-mil coating on each side of the film of a formulation based on the ammonium salt of 2-amino-5-nitro benzene sulphonic acid. Coating the inside walls and bottom of a conventional rifle magazine with intumescent formuations was demonstrated to be incapable of preventing round-to-round propagation.
