Hydroxyl-terminated polybutadiene (HTPB) is widely used as a binder in solid rocket propellants due to its excellent mechanical properties and compatibility with various oxidizers and fuels. It provides structural integrity and flexibility to the propellant, ensuring efficient combustion and stability under extreme conditions.

In the automotive industry, HTPB is utilized in the production of polyurethane foams and adhesives, offering durability and resistance to wear and tear. It is also employed in sealants and coatings, providing protection against moisture, chemicals, and environmental factors.

Additionally, HTPB finds applications in the manufacturing of waterproofing materials and elastomers, where its high elasticity and resilience are critical. Its ability to form strong bonds with other materials makes it a valuable component in composite materials and industrial adhesives.

In the aerospace sector, HTPB is used in the development of lightweight, high-performance materials that can withstand harsh conditions. Its versatility and reliability make it a key ingredient in various advanced engineering applications.
