In the manufacture of Extex (XTX 8003, 80% PETN, 20% Sylgard silicone rubber), the formulation is mixed for about five hours. Freon MF is added in the proportions of fur pounds Extex to one quart Freon, to enhance the mixing at lower power than would otherwise be the case. After mixing, the formulation is milled on a three-roll rubber mill for a total of 25 passes. The study of the effects of roll milling on Extex was started; the visual results are indicative that a considerable reduction in crystal size occurs during the formulation process
