Glycidyl Azide Polymer is one of the most important energetic binders that is used in the composite solid propellant formulation. GAP is a unique binder with a positive heat of formation (+117.2 kJ⁄mol). In addition, GAP has good thermal and physical properties such as low glass transition temperature, low viscosity and high density compared to other energetic binders. GAP can be used as a binder and energetic plasticizer in preparation of PBX, composite and double base propellants lead to increase their performance. In addition, this polymer is used for preparation of low vulnerability ammunition (LOVA) and green propellants. In this paper, the studies on thermal properties of polyurethanes based on GAP by DMTA, DSC and TGA, and their mechanical properties such as tensile strength and strain and hardness have been investigated.

Keywords: Glycidyl Azide Polymer, Polyurethane, Thermal properties, Mechanical properties.
