An important application of HTPB is in solid rocket propellant.It binds the oxidizing agent, fuel and other ingredients into a solid but elastic mass in most composite propellant systems.The cured polyurethane acts as a fuel in such mixtures. For example, HTPB is used in all 3/4 stages of the Japanese M-5 launch vehicles and in 1/3 stages of the Indian PSLV launch vehicle.

RCS Hydroxyl-terminated Polybutadiene (HTPB) resin has a functionality of 2.4 - 2.6, which results in a higher crosslink density than lower functionality HTPB with the better room temperature curatives (like our modified MDI isocyanate), without resorting to other ingredients that can adversely affect the cure chemistry.
