Many promising elastomers and energetic binders are reported in the literature for their probable application in propellant formulations. However, their application in actual systems is still restricted due to many inherent limitations. Therefore, an attempt has been made to study the performance of an advanced energetic solid propellant based on an energetic binder comprising a polyol with high hydroxyl functionality plasticized with 1,2,4-butanetriol trinitrate (BTTN). In order to examine the physico-chemical properties of the BTTN/Polyol binder system, the polyol and a series of binders have been formulated and cured with different di-isocyanates viz. TDI, IPDI and H12MDI, and the cured binder sheets were evaluated for their mechanical properties, decomposition temperatures and glass transition temperatures (Tg). The pot life of a representative binder system with various di-isocyanates has also been determined using a gelation timer apparatus. The overall result of this study establishes that the energetic binder system under study has potential applications in the formulation and processing of advanced energetic solid propellant compositions for case bonded rocket motors, offering higher density, higher energy and better low temperature strain capability as compared to conventional HTPB-based composite propellants.
