Solid propulsion is a critical element, accounting for 50-80% of a missile's total mass as it serves as the primary energy source. In solid rocket propulsion, polymers play dual roles. First, they act as a polymeric binder matrix for solid oxidizer-embedded propellants. Second, they serve as thermal insulators to protect key components, such as the casing and nozzle, from the high-temperature propellant flame. This presentation will begin by introducing the various polymers used in solid propellants and thermal insulation. It will then delve deeper into the polymers specifically utilized for solid propellants, examining their polymer chemistry, such as crosslinking reactions through step-growth polymerization. Finally, the presentation will conclude with a brief overview of potential polymers and their corresponding matrices that hold promise for future sustainable solid propellants.
