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.

2019年11月2日 · For nearly 60 years, and at least two generations of scientists and engineers, hydroxyl-terminated polybutadiene (HTPB) has enjoyed a prominent place in the Defense business.

Hydroxyl-terminated polybutadiene (HTPB) is a flexible telechelic compound with a main chain containing a slightly cross-linked activated carbon–carbon double bond and a hydroxyl group at the end.

2012年12月5日 · Hydroxy (or) hydroxyl terminated polybutadiene is popularly known as HTPB resin. It is a telechelic liquid rubber having low molecular weight polymer of polybutadiene terminated at each end with a ...

Hydroxyl terminated polybutadiene (HTPB) exhibits several highly valued properties, such as a strong solid-loading capacity, a low glass transition temperature (Tg), good ageing resilience, and robust elongation capacity.

2018年7月1日 · Hydroxyl-terminated polybutadienes (HTPBs) were obtained via free radical polymerization, living anionic polymerization, and ring-opening metathesis polymerization.

HTPB is the most common prepolymer binder material. It allows a high solid fraction (88 to 90% of AP and Al) and relatively good physical properties at the temperature limits [Sutton and Biblarz, 2017] There exist several different chemical formulae for HTPB.

2023年1月11日 · OBJECTIVE: Establish combined modern analytical methods and a resultant predictive model for characterizing Hydroxyl Terminated PolyButadiene (HTPB) polymer binder resin in parallel with chemical cure, mechanical properties, and aging assessments, to support the successful development and use of military grade HTPB in existing and emerging solid...

2025年1月6日 · Hydroxyl-terminated polybutadiene (HTPB) is a liquid rubber with a long non-polar carbon chain. Because of its low glass transition temperature, high elasticity, high water resistance, and hydrophobicity, HTPB is widely used in …

2019年6月27日 · Hydroxyl terminated polybutadiene (HTPB) as a telechelic liquid polymer has been widely used in propellants and explosives and many modified-HTPBs have been reported in the literature.
