Polycene (Burning Rate Accelerator)
Polycene is burning rate catalyst which leads to a higher burning rate with low pressure exponent without migration, vaporization and oxidation during missile manufacturing and aging. Polycene unlike ferrocene derivatives doesn't have potential risk of the dangers. Also, Polycene allows it to be fully miscible with standard HTPB (Hydroxy Terminated Polybutadiene).
| Chemical Name | Polycene® / Butacene 800 |
|---|---|
| Generic Name | Organic silicon ferrocene derivatives bonded to HTPB |
| CAS# | 125856-62-4 |
| Iron Content | 7.5~8.5% |
| Percent volatile | < 0.1 % |
| Hydroxyl index, meq/g | 0.32 ±0.05 |
| Viscosity | ≤ 1000 poise at 25 degrees Celsius |
TPB (Solidifying Catalyst)
Triphenyl bismuth(TPB) has been used as the solidifying catalyst for butyl hydroxyl propellant of high combustion velocity. TPB can lower solidifying temperature and optimize solidifying time for pot life, as well as there is not any by-effect for its processing performance and mechanics properties. In addition TPB can be also used as the catalyst for ethylene polymarization into cyclooctatraene, formaldehyde polymarization, the curing agent for polycyclochlorides, and other some monomers’ polymarization etc.
