Hydroxyl-terminated polybutadiene (HTPB) is widely used as a binder in solid rocket propellants due to its excellent mechanical properties and compatibility with oxidizers. It acts as a fuel source and provides structural integrity to the propellant grain, ensuring stable combustion. In the automotive industry, HTPB is utilized in the production of polyurethane foams and adhesives, offering flexibility and durability. It is also employed in coatings and sealants for its resistance to water, chemicals, and weathering. Additionally, HTPB finds applications in the manufacturing of elastomers and impact modifiers, enhancing the performance of various industrial materials.
