3. Usage                                                                                                                            

  • TPB has been used as the solidifying catalyst for butyl hydroxyl propellant of high combustion velocity.
  • TPB can lower solidifying temperature and shorten solidifying time for the propellant

(The consulted usage quantity for TPB is 0.006%-0.05% of total weight for 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 cyclooctatraene, the catalyst for formaldehyde polymarization, the curing agent for polycyclochlorides, and catalysts for other some monomers’ polymarization etc.

 4. Safety notes                                                                                                                 

It's toxic,If contacting with eyes or skin can lead to inflammation. To swallow or to inhale it is harmful. When handling it should be wear protective clothing, synthetic rubber gloves, poison protection gauze mask and protective eye goggles.
