Hydroxyl-terminated polybutadiene (HTPB) is widely used as a binder in solid rocket propellants due to its excellent mechanical properties and compatibility with oxidizers like ammonium perchlorate. It provides flexibility, adhesion, and structural integrity to the propellant, ensuring efficient combustion and stability during storage and operation. In the automotive industry, HTPB is utilized in the production of polyurethane foams and coatings, offering durability and resistance to wear and tear. It is also employed in adhesives and sealants, where its strong bonding capabilities and resistance to environmental factors make it suitable for construction and industrial applications. Additionally, HTPB is used in the manufacture of waterproofing materials, providing long-lasting protection against moisture in various structures. Its versatility and performance make it a valuable material in aerospace, automotive, and industrial sectors.
