3. Application2,2′-Bis(ethylferrocenyl)propane (catocene) 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. PackingTwo plastic casks in a wooden case. Net Weight: 10 kg/cask; 20 kg/case

6. StorageStored in a cool, ventilated place. Casks should be sealed with nitrogen. Avoid heat and exposure. The shelf life is 12 months after manufacturer date. It is still available if retest result is qualified after expire date.

7. TransportationKeep upright when transported. Avoid violent collision and exposure Do not transport with strong oxidizers.
