Thermal expansion is an intrinsic property of every material. The thermal expansion of LX-17, PBX-9502 and ultrafine triaminotrinitrobenzene (TATB) had already been reported; however, there are few reports on the expansion of RDX-based compressed explosives. In the present work, the thermal expansion of RDX associated with a polymeric environment of paraffin wax, in the ratio of 95% and 5%, was investigated using a thermomechanical analyzer (TMA). Fourier Transform IR (FTIR), Differential Scanning Calorimetry (DSC) and a Thermal Property Analyzer (TPA) were used to characterize and study the thermal properties of pressed RDX/wax explosive beads. The values of the coefficient of thermal expansion (CTE) and linear thermal expansion were measured and analyzed in the temperature range from -100 to 100 °C. Volume and density changes over the entire temperature range were evaluated. The irreversible growth of RDX-based compressed explosives was also observed. The results are related to the growth of RDX/wax-based explosive pellets due to repeated thermal stress.
