Product use

The triphenyl bismuth (TPB) is used as a solidifying catalyst for high flammable butyl hydroxypropellant. TPB can reduce the curing temperature of the propellant, shorten curing time, and the processing performance and mechanical properties of no side effects, dosage of TPB reference is 0.006% ~ 0.05% of the total propellant, 50 in curing time is 7 days, also can be used as acetylene polymerization cyclization symplectic four tin chloride catalyst, polymerization catalysts, poly formaldehyde ring curing agent, certain other monomer polymerization catalyst.
