Review of novel energetic polymers and binders – high energy propellant
Current solid rocket propellant formulations still employ traditional ingredients utilized since the 1960s, such as hydroxyl terminated polybutadiene (HTPB). Recent advances in energetic polymer see many binders capable of providing higher specific impulse and burn rates over HTPB.

This patent discusses high energy, low radar attenuation propellant comprising of 1 25-55 weight percent of a binder which itself comprises from 2-25 weight percent of a copolymer of acrylic acid and a lower alkyl acrylate and 75-98 weight percent of an energetic difluoroamino group containing plasticizer, 2 0-15 weight percent aluminum or boron 3 45-75 weight percent of an oxidizer and 4 12-5
Screening of polymer-plasticizer systems for propellant binder
Composite propellants of advanced propulsion systems demand high energy, sufficient structural integrity, and low temperature capability. Polymers and plasticizers contribute to all these three...
Influence of the Binder Structure on the Interfacial Adhesion and
The propellant used a 30 mm propellant grain with a thickness of about 10 mm, the transition layer used a 30 mm sheet with a thickness of about 1 mm, and the liner used a 30 mm HTPB sheet with a thickness of about 1.5 mm. Samples were placed at 40, 50, 60, and 70 °C for migration experiments.
- Can energetic binder systems improve the output of cast cured polymer bonded explosives?
- The use of energetic binder systems is a promising means of enhancing the output of cast cured polymer-bonded explosives and cast composite rocket propellants. This technology shows promise for use in high performance cast cured explosives for volume constrained and metal accelerating applications, and in advanced minimum smoke rocket propellants.
- What type of plasticizer is used in solid rocket propellant?
- According to Mohd Nurazzi et al. , some plasticizers are classified based on their molecular weight, and the most prevalent plasticizer type used in polymer industries, including solid rocket propellant applications, is the low molecular weight type, which consists of non-volatile, non-reactive esters that are compatible with the binder matrix.
- What is solid composite rocket propellant?
- Solid composite rocket propellant is commonly employed in military applications, such as in a rocket missile fuel engine. However, ongoing research is still being conducted on the material composition, fabrication process, and design of the grain structure to modify the performance of rocket motors.

- Which polymers are energetic binders?
- Miscellaneous nitrogen-containing polymers that have found use as energetic binders include polyvinylnitrate, polynitrophenylene, nitramine polyethers and N,N'-bonded epoxy binders. Recently the inert poly(furfuryl glycidyl ether) has also been identified as a possible route to energetic binders .
- Does a plasticizer migrate to the insulation layer of a rocket motor?
- However, the migration of the plasticizer to the insulation layer of the rocket motor is the primary concern regarding the plasticizer's behaviour based on simulation and experimental analysis. This phenomenon will have an effect on the grain's mechanical properties.
