Product Usage

Triphenylbismuth (TPB) is used as a curing catalyst for high-burning-rate HTPB propellants. TPB can reduce the curing temperature of the propellant, shorten the curing time and have no adverse effects on its processing and mechanical properties. The reference dosage of TPB is 0.006%-0.05% of the total propellant, and the curing time at 50℃ is 7 It can also be used as a catalyst for the polymerization of acetylene to cyclooctane tin, a catalyst for formaldehyde polymerization, a curing agent for polycyclochloride, and a catalyst for the polymerization of some other monomers.
