Hydroxyl-terminated polybutadiene HTPB is an oligomer of butadiene terminated at each end with a hydroxyl functional group. It reacts with isocyanates to form polyurethane polymers. HTPB is a translucent liquid with a color similar to wax paper and a viscosity similar to corn syrup. The properties vary because HTPB is a mixture rather than a pure compoundand it is manufactured to meet customers' specific requirements.
RHTLO has a functionality of 2.
This provides side-to-side linkage for a stronger cured product. HTPB is usually cured by an addition reaction with di- or poly- isocyanate compounds. Polyurethanes prepared from HTPB can be engineered for specific physical properties; polyurethanes may be highly elastic or tough and rigid.
Some products include: rigid foam insulation panels; durable elastomeric wheels and tires used for roller coastersescalatorsskateboardsetc. An important application of HTPB is in solid rocket propellant. It binds the oxidizing agentfuel and other ingredients into a solid but elastic mass in most composite propellant systems.
The cured polyurethane acts as a fuel in such mixtures. Similar propellants, often referred to as APCP ammonium perchlorate composite propellant are used in larger model rockets. A typical APCP produces 2—3 times the specific impulse of the black powder propellant used in most smaller rocket motors. HTPB is also used as a hybrid rocket fuel.
