CTPB is primarily used as a binder in solid propellants for rockets and missiles. It provides excellent adhesion and mechanical properties, ensuring the propellant maintains its structural integrity under extreme conditions. Additionally, CTPB is utilized in the formulation of explosives and pyrotechnics due to its stability and compatibility with various oxidizers and fuels. Its elastomeric nature also makes it suitable for use in sealants and adhesives in aerospace and industrial applications, where high performance and durability are critical.
