  • What are energetic binders?
  • Energetic binders are polymers which crosslink explosive ingredients together with a plasticiser into a tough yet flexible three-dimensional network. Plasticisers are typically added both to facilitate processing and to improve mechanical properties of the final cured formulation. This review comprises two main sections.
  • 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 .
  • 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 is a polymeric binder?
  • Once cured, the polymeric binder is a tough elastomeric rubber capable of absorbing and dissipating energy from hazardous stimuli, lending itself well to EM applications. This general document outlines the most promising energetic polymers and plasticisers being considered today.
  • What are energetic plasticisers?
  • Energetic Plasticisers The primary role of energetic plasticisers in energetic material formulations is to modify the mechanical properties of the charge to improve safety characteristics. This is achieved by softening the polymer matrix and making it more flexible.
  • Which polymer is used to encapsulate explosives?
  • Nowadays, the current practice is to encapsulate the explosive in a binder, composed of a polymer such as hydroxy- terminated polybutadiene (HTPB) crosslinked with isocyanates, and containing a plasticiser such as dioctyl adipate (DOA). Other polymers include carboxy-terminated polybutadiene (CTPB) and hydroxy-terminated polyethers (HTPE) .
