CTPB is primarily used as a binder in solid propellants for rockets and missiles. Its excellent adhesion properties and flexibility make it ideal for bonding fuel and oxidizer particles, ensuring structural integrity and consistent performance under extreme conditions. Additionally, it is employed in the production of composite materials, where its elastomeric characteristics enhance durability and resistance to mechanical stress. CTPB is also utilized in specialized adhesives and sealants, particularly in aerospace and defense applications, due to its ability to withstand high temperatures and harsh environments.
