SINOPSIS

For safe handling and use of high explosives, waxes have been used to desensitize military high explosive compositions consisting of relatively sensitive explosive ingredients. In addition to the principal purpose of desensitization, the waxes also act as binders, lubricants, and sealants. It is well known that the type of wax used in the desensitization of explosive compositions will affect the quality of cast explosives.. The objective of this paper is to characterize two different waxes and examine the role of molecular weight. To this end, the experimental approaches capable of providing structural as well as molecular weight information were selected for this study. These are direct exposure probe mass spectrometry (DEPMS) and supercritical fluid chromatography (SFC). In addition, comparative differential scanning calorimetry (DSC) of both waxes was conducted to determine the melting and cooling characteristics of both waxes.
This paper will briefly describe the experiments and discuss the results obtained. The discussion will include the feasibility of using a 'designer wax' tailored for desensitizing any particular high explosive composition.
