A New Energetic Mixed Formal Plasticizer, Using Diformal as
BDNPF/A is a useful energetic plasticizer, but mixed formal, which consists of BDNPF, DNPBF, and BDNBF, is anticipated to be better than BDNPF/A in chemically, thermally and economically. Last year, we successfully synthesized and characterized the mixed formal that has minimum contents of diformal.

Design, synthesis and characterization of new energetic
In this study, a new class of energetic phthalate plasticizers based on imidazolium ionic liquids (ILs) were synthesized. The structure of the synthesized compounds was confirmed by 1HNMR, 13CNMR, and FT-IR. The thermal stability of nitrocellulose (NC)/plasticizer blends was also evaluated by thermogravimetric analysis (TGA). The compatibility of the NC with three synthesized energetic
Examining the compatibility of energetic plasticizer DNDA-5
This paper describes the synthesis and characterization of two novel tetra-azido energetic plasticizers from readily available commercial sources possessing good thermal stability. Two new
Synthesis and characterization of bis(2,2-dinitropropyl
The GAP-based PUs were plasticized with 0, 33 and 50 wt% of an energetic plasticizer with a mixed TPB/DNS catalyst at an OH/NCO equivalent ratio of 1. The GAP polyol prepolymer and required amount of an energetic plasticizer were premixed at 60 °C under vacuum for 1 h and cooled to 25 °C for 0.5 h. IPDI and HDI (1:1 ratio of NCO equivalent
- What is the difference between conventional and nonenergetic plasticizers?
- (1) The conventional plasticizers usually have inert and stable carbon–hydrogen-based backbone and are used in all kinds of applications. However, for energy-based applications, mixing the ingredients of the composite polymer matrix with nonenergetic plasticizers dilutes the overall energy content of the energetic system.
- What are 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 system.
- What was the first energy plasticizer?
- The first energetic plasticizer developed for commercial application and still widely used is nitroglycerine (NG) or glyceroltrinitrate. NG was first discovered in 1846. It has a high oxygen balance of +3.5 that improves the energy content of the overall composite mixture.
- Which energetic plasticizer has the highest melting point?
- For example, bis (2-fluoro-2,2-dinitroethyl)formal (FEFO) is a fluoro-nitro energetic plasticizer having a melting point of 14 °C and is reported to have the highest density (1.60 g/cc) for any energetic plasticizer currently in use.
- What are the patents for dinitropropyl fluorodinitroethyl formal plasticizer?
- US Patent 3962349, 1976. Adolph, H. G. Dinitropropyl fluorodinitroethyl formal plasticizer and method of preparation. US Patent 4453021, 1984. Koppes, W. M.; Adolph, H. G. Bis (2,2,2-fluorodinitroethoxy)- (1,1,1-fluorodinitro-2-propoxy) methane. US Patent 4756777, 1988.
- What are plasticizers used for?
- The general role of plasticizers is to increase the flexibility or processability of plastics/polymers used in a wide range of applications from automobile industry to healthcare and consumer products. Plasticizers help in improving the mechanical properties of the composite matrix, especially the binder.
