Triphenyl Bismuth USES

Triphenyl bismuth (TPB) has been used as the curing catalyst of high burn rate HTPB

propellant. TPB could reduce curing temperature and curing time, with no side-effect on the processing and

mechanic properties of the propellant. The suggested dosage of TPB is 0.006wt%-0.05wt% of the propellant. The

curing time is about a week at 50℃. TPB can also be used as the catalyst of the polymerization from ethyne into

cyclooctatetraene, polymerization of formaldehyde other monomers etc. It also can be applied to the curing agent

of polycyclochlorides.
