3. Application：2,2′-Bis(ethylferrocenyl)propane has been used as an efficient burning rate catalyst in composite solid propellants, which is possessed of the features of excellent overall and small removing properties. As a kind of bisferrocene derivative, 2,2′-bis(ethylferrocecnyl)propane can improve the combustion rate and reduce the pressure exponent with the application of AP-based oxidizer in composite solid propellants.
4. Safety instructions: Low toxic. LD50(Rat): > 20,000 mg/kg; Mouse, oral: LD50> 500mg/kg.
5. Packing：Two plastic casks in a wooden case. Net Weight: 10 kg/cask; 20 kg/case
