Benzotrioxofurazan (BTF) -based composite explosives containing three different binder components were prepared in this study, using nitrocellulose (NC), thermoplastic polyurethane (Estane), and fluororubber 2602 (F2602) as binders, through the electrostatic spray method. The objective was to reduce the sensitivity of BTF. The BTF-based composite explosives were characterised using a range of scientific equipment, including scanning electron microscopy (SEM), Fourier Transform infrared spectroscopy (FT-IR), DSC thermal analysis, and mechanical sensitivity. The SEM results indicated that the BTF-based composite explosives’ particle size was between 50 and 100 nm, and had a spherical shape. Compared with the raw BTF, the critical temperature of thermal explosion of the three composite explosives, BTF/NC, BTF/Estane and BTF/F2602, was increased by 4.21, 6.8 and 9.44 °C, respectively. These increases indicate an improvement in the thermal stability of the samples. The characteristic drop height of BTF/NC, BTF/Estane and BTF/F2602 was 68.12, 62.34 and >80 cm, respectively. Additionally, the explosion percentage of BTF/NC, BTF/Estane and BTF/F2602 had been decreased to 24%, 24%, and 8%, respectively. These results suggest a significant enhancement in the safety performance of all three samples.
