A plastic mouldable explosive composition comprises a gelled binder and a particulate explosive filler contained in the binder, wherein the binder comprises a blend of polyethylene wax polymer together with a tackifying resin comprising a polyisobutene polymer. Desirably, the amount of the polyethylene wax polymer in the composition is in the range 2 to 35 per cent by weight, the polyethylene polymer having a molecular weight in the inclusive range 3,000 to 15,000. Desirably, the polyisobutene polymer comprises a liquid polyisobutene having a molecular weight of from 500 to 7,000.
