Hexogen was mixed with (i) polyisobutylene dissolved in dioctyl adipate, (ii) butadiene-styrene rubber suspended in H2O, or (iii) H2O-suspended fluoro-polymer to which dibutyl phthalate dissolved in Me2CO was added and then Me2CO was evaporated. Cone penetrations were measured (Polish Standard PN-79/C-04133) over -40degreesC-70degreesC for (a) hexogen (88%) containing polymer (i), (ii) or (iii), (b) hexogen (84%) containing 2, 3, 4, or 5% of the rubber and 14, 13, 12, or 11% of dioctyl adipate, resp., (c) a 92.5, 90.8 and 88.4% hexogen containing 2.8, 3.4 and 4.1% of fluoro-polymer and 4.7, 5.8 and 7.5% of dibutyl phthalate resp., (d) hexogen (84%) containing 4% of rubber and 12% of dioctyl sebacate, dibutyl phthalate or dioctyl adipate as plasticizer, (e) rubber-bound hexogens (84, 86 and 88%), particle size 0.02-0.125 mm, (f) hexogen (84%) containing 0.5% lecithin or 0.5% glycerin stearate as modifier, (g) hexogens (84, 74, 64%) containing 4% of rubber and 12% of dioctyl adipate and 0, 10, or 20% of powdered Al as additive. Polymer is the crucial binder. Plasticizer should be selected individually for the polymer used. As hexogen content was increased, plasticity fell. Plasticity was more affected by polymer than by explosive content. The stearate was the most effective as modifier. Plasticity and explosive power rose as Al content was raised.
