Influence of 1,4-butanediol on hydroxyl-terminated poly(butadiene) based composite propellant binder characteristics [PDF]

Scientific Technical Review, 2015
1.4-butanediol, as a chain extender, was incorporated into a hydroxyl-terminated poly(butadiene) based composite rocket propellant binder composition. As curing agents, isophorone diisocyanate (IPDI) and toluene diisocyanate (TDI) were used.

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 ...

Azide and Alkyne Terminated Polybutadiene Binders: Synthesis, Cross-linking, and Propellant Studies

, 2016
In composite solid propellants, the fuel and oxidizer are held together by a polymer binder. Among the different types of polymeric binders used in solid propellants, hydroxyl terminated polybutadiene (HTPB) is considered as the most versatile.

Thermal and mechanical reinforcement of a novel paraffin-based hydroxyl-terminated polybutadiene (HTPB) binder containing a three-dimension (3D) diurea–paraffin wax (DU–PW) for prevention of PW leakage

RSC Advances, 2018
DU is creatively used as supporting materials to shape-stablize PW. The prepared DU–PW composite can effectively improve the thermal and mechanical properties of PW/HTPB, indicating a prospect to prevent PW leakage in PBX.

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 ...
