Design, synthesis and characterization of new energetic
The most popular plasticizers of double-based propellants are those that contain ester groups such as diethyl, dibutyl and dioctyl phthalates which are a class of neutral plasticizers.16–18Recently, ILs are used as energetic plasticizers as their easy synthesis, low volatility and high-temperature stability.12
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.
New Plasticizers based on Alternative Raw Materials
BASF – Plasticizers – Toys. A long-standing and fruitful relationship Plasticizers are used to make plastic softer and more flexible. There has been a need for plasticizers ever since PVC (polyvinyl chloride) was patented in 1913. In its unmodified state, PVC is rigid and brittle. Plasticizers are used to make the material soft and flexible.

Energetic Polymers | Emerging nanoscience Research Institute
EnRI has successfully synthesized energetic polymer plasticizers namely; low molecular weight GAP and azido terminated GAP (GAP-A). These energetic polymer based plasticizers are structurally similar to binder matrix and resist the migration due to enhanced miscibility. Low molecular weight (Mw= 650 to 800 g/mole) GAP polymers have been
- What are energetic plasticizers?
- In modern energetic propellant composition, conventional plasticizers are being gradually replaced by energetic plasticizers having nitro, nitroamino, azido and other energetic groups or combination of energetic groups in the same molecule.
- Are energetic plasticizers a good choice for solid propellant formulations?
- In modern solid propellant formulations, conventional plasticizers are being gradually replaced by energetic plasticizers (EPs), which usually have various energetic groups (such as nitro, nitroamino, azido, etc.) in the molecules to enhance the energy performance. Thus, extensive efforts have been devoted to the design and synthesis of new EPs.
- 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 are plasticizers used for?
- As an important ingredient of composite explosives and solid propellants, plasticizers are usually liquid organic compounds that are added to propellants to improve their mechanical properties. In modern solid propellant formulations, conventional plasticizers are being gradually replaced by energetic plasti 2022 Focus and Perspective articles
- What are energetic phthalate plasticizers based on imidazolium ionic liquids?
- 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 1 HNMR, 13 CNMR, and FT-IR. The thermal stability of nitrocellulose (NC)/plasticizer blends was also evaluated by thermogravimetric analysis (TGA).
- Why are plasticizers used in propellant formulations?
- The common plasticizers are inert, so they cause to reduce the energetic properties of explosives and propellants. Energetic plasticizers have been used in propellant formulations in order to improve their mechanical properties and specific impulse. 1, 2
