Energetic
Binder for use in Rocket Propellants
Introduction
High-energy rocket propellants are required to possess improved
performance, satisfy insensitive munitions comply with environmental
aspects and reduced costs. As such, resent advances in propellant
research, are aimed at developing high energy binders which
give better performance than the commonly used binder Hydroxy
Terminated Poly-butadine (HTPB) and which are compatible with
eco-friendly oxidizers Ammonium Nitrate (AN), Hydrazinium
Nitroformate (HNF) or Ammonium Dinitramide (ADN). Polymeric
azides that include Glycidyl Azide Polymer (GAP) and its copolymers
contain azide groups along the polymer chain as pendent groups,
which make them highly energetic. These polymers can therefore
be used as energetic binders having minimum smoke, reduced
pollution and sensitivity. In addition to being fuel rich,
these propellants liberate large amounts of Hydrogen, Nitrogen,
CO and gaseous hydrocarbons on burning and provide high burning
rate.
Special Features:Possess
high burn rate; Acts as a high energy binder; Has excellent
elastomeric characteristics; The product is devoid of bubbles;
Generates high energy output; Has high char yield; High efficiency;
Can be produced by economical and eco-friendly process without
stringent conditions
Prospective
Users: For the production of High Energy rocket propellents
