New plasticizers for energetic materials | SpringerLink
Specific features of the synthesis of new nitroxy-containing N,N′-bis(alkylnitramine) mixtures have been considered. The results of studying the plasticizing ability of the mixtures with respect to various cellulose nitrates, as well as the performance data on energetic materials on their basis, have been reported. Combustion of both the plasticizers and compositions on their basis has been
Studies of Energetic and Non‐Energetic Plasticizers
Binders with energetic plasticizers besides boosting energy also enhance the structural integrity of the propellant composition. In recent energetic compositions, energetic plasticizers such as NG, BTTN, DEGDN and TEGDN replace conventional plasticizers as they possess positive heat of the explosion and energetic groups in the same molecule.
Simple and Green Synthesis of a Novel Fluoro-Nitrato
plasticizers known so far.3 Density is important for energetic plasticizers as it is a characteristic measure of the energetic content of a molecule. Furthermore, in terms of thermal stability, T dmax of ACR-ENP-1 was found to be 128 °C (Figure 3), which was much higher than most commonly used energetic plasticizer NG and other nitro-based
Energetic Polymers: Binders and Plasticizers for Enhancing
Energetic Polymers: Binders and Plasticizers for Enhancing Performance | Wiley This up-to-date overview provides the latest information on the performance, sensitivity, strength and processability aspects of propellants and explosive formulations, with the nature of polymer binder/plasticizer as the variable factor.
Survey of New Energetic and Eco-friendly Materials
Use of new powerful and green oxidizers like ADN, HNF and ammonium ozonide along with energetic binders like GAP, BAMO and BAMO-THF copolymer can boost specific impulse (I s) to more than 320 s. Inclusion of energetic plasticizers like tetra azido malonate and tetra azido glutarate can enhance energy further.
- What are energetic plasticizers?
- Plasticizers are functional additives that have been widely utilized to enhance the mechanical properties and processing technology of explosive systems. However, due to the increasing demand for energetic formulations of explosives and propellants, traditional plasticizers are gradually being replaced by energetic plasticizers.
- What are energy plasticizers used for?
- Energetic plasticizers have been used in the propellant industry for improving mechanical properties of propellant formulations and to boost energy.
- What is azido plasticizer?
- Azido plasticizer, a type of energetic plasticizer, possesses excellent thermal stability and low glass transition temperature. However, the incorporation of a single azido group can lead to issues such as decreased oxygen balance and reduced density. In recent years, novel azido plasticizers containing various energetic groups have been developed.
- Which reagent is used to introduce azido groups in energetic plasticizers?
- For azido groups, the introduction of azido groups in energetic plasticizers is to use -N 3 in nucleophilic reagent NaN 3 to replace halogen (-X) , trifluoromethane sulfonate (-OTf) , nitrate ester (-ONO 2) and other leaving groups.
- How many types of Energetic plasticizers are there?
- Fig. 1. Structure and properties of representative energetic plasticizers. Despite the reporting of over 20 types of azidonitramine energetic plasticizers, there is no comprehensive summary or analysis of these substances.
- Are nitramine plasticizers a promising research direction?
- Among these, the introduction of a nitramine group into the azido plasticizer has shown significant improvements in oxygen balance, density, and sensitivity compatibility. This makes azidonitramine plasticizers a promising research direction in the development of energetic plasticizers.
