Hydroxyl-terminated polybutadiene (HTPB)

Hydroxyl-terminated polybutadiene (HTPB) is a synthetic rubber-like material commonly used as a binder in solid rocket propellants. It has chemical groups that contain hydroxyl (–OH), which allows it to bond well with other chemicals. HTPB is valued for its flexibility, durability, and ability to withstand extreme temperatures. In addition to rocketry, it is also used in coatings, adhesives, and elastomers due to its excellent mechanical properties. Overall, HTPB plays a crucial role in various applications where strong, resilient materials are needed.
