Function and use:

Triphenyl bismuth (TPB) has been used as the solidifying catalyst for butyl hydroxyl propellant featuring high combustion velocity. TPB can lower solidifying temperature and shorten solidifying time for the propellant, as well as there is no by-effect for its processing performance and mechanics properties. The recommended dosage for TPB is 0.006%-0.05% of total weight of the propellant. Its solidifying time in 50°C is 7 days. In addition, TPB can be also used as the catalyst for ethylene polymarization into cyclooctatetraene, the catalyst for formaldehyde polymarization, the curing agent for polycyclochlorides, and catalysts for other some monomers’ polymarization etc.
