Comparative Assessment of Energetic Plasticizers Including NFPEG3N3 in a GAP/HMX Formulation: Mechanics, Stability, Combustion, and Performance

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 2, Page 269-276, February 2026.
ABSTRACT We examine the new energetic plasticizer 3‐(2‐(2‐(2‐azidoethoxy)ethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG3N3), three reference compounds (BDNPA/F, Bu‐NENA, and DNDA‐57), and a plasticizer‐free control in a fixed HMX/GAP composite. NFPEG3N3 provides the strongest low‐temperature properties, yielding the lowest formulation glass transition ...

Rheological Characterization of Low and High‐Solids‐Loaded Suspensions Using Capillary Rheometry

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 1, Page 144-156, January 2026.
ABSTRACT Controlled extrusion of viscous liquids with suspended solids depends critically on rheology. The rheology of a binder (9:1 mass ratio of cellulose acetate butyrate (CAB) to triacetin with a 55 wt.% diethyl ketone balance) loaded with dilute (0–15 wt.%) and concentrated (≥50 wt.%) granulated sugar loadings from three particle size ...
