Full article: Review of novel energetic polymers and binders
With the addition of nitro groups, N-HTPB is miscible with energetic plasticizers with superior oxygen balance and burn rate than HTPB. N-HPTB has shown to be thermally stable up to 170°C, and propellants using N-HTPB also shows higher density and burn rate than propellants using HTPB as its binder [Citation 10, Citation 41 – Citation 45
Understanding the alkyl effect of geminal
In other words, DNPNc can endow superior tuning effects on the low temperature behavior of HTPB. Therefore, the above-obtained results consistently indicated that DNPNc could be a good candidate to replace DOS and DOA as insensitive energetic plasticizers for HTPB based formulations.
Song Ma, Wenqian Du and Yunjun Luo* Simulation of GAP/HTPB
Among them, glycidyl azide polymer (GAP) has drawn tremendous attention due to its high formation enthalpy, high density and low sensi- tivity. It is a promising energetic binder of advanced pro- pellants. Bis(2,2-dinitropropyl) formal/acetal (A3) was developed as an insensitive energetic plasticizer for the azido-propellant formulations (9–11).
Novel Geminal Dinitro Esters As Energetic Plasticizers
The main focus of energetic plasticizers is to enhance the mechanical properties and safety characteristics of the energetic formulation without diluting the overall energy content of the...
Screening of polymer-plasticizer systems for propellant
Simulated and experimental data proved that energetic plasticizers are not miscible with hydroxyl terminated polybutadiene (HTPB), while n-Butyl-nitratoethylnitramine (Bu-NENA) was found to...
