GAP-diol Molecular Structure
DongIn Chemical GAP-diol polymer binder sample for aerospace propellant applications
Company Overview
DongIn Chemical specializes in producing high-quality Glycidyl Azide Polymer (GAP-diol), a thermally stable polymer binder optimized for aerospace propellant applications. Our GAP is proven to be equal to or superior in performance compared to commercially available GAPs, ensuring reliable quality and excellence for demanding applications.
In particular, the molecular weight and hydroxyl number can be arbitrarily adjusted to suit consumer needs. With vacuum thermal stability at 1.0 or less, our GAP offers excellent long-term storage properties for propellants.
A binder specimen prepared from our GAP demonstrated mechanical properties—including high tensile strength, elongation, and adhesive strength—suitable for propellant application. It has passed all standard ground combustion tests across various temperatures (room temperature, high temperature, low temperature), validating its robust performance.
