Paris-based Societe Nationale des Poudres et Explosifs (SNPE) France has recently developed a new binder known as butacene (a ferrocene derivative chemically bound to the HTPB backbone) for composite propellants. The butacene-based composite propellants are available for use and have higher burn rates compared with HTPB. In addition, the chief advantage of this binder is that the same facilities which are used for the manufacture of HTPB-based propellants, can be used for the manufacture of butacene-based composite propellants as well. 

The same explosives were formerly employed in Russia, where the mining explosives industry was financed by French capital. In both countries Favier Powders (Poudres Favier) or Favier explosives (Explosifs Favier) were also employed. Their composition is tabulated below.

Two kinds of nitrocellulose were used in France at the time of the first World War, coton-poudre No. 1 (CPi), insoluble in ether-alcohol and containing about 13% nitrogen, and coton-poudre No. 2 (CP2), soluble in ether-alcohol and containing about 12% nitrogen.96 CPi thus contained a little less nitrogen than the material which we are accustomed to call guncotton, and CPi contained a little more than the material which we are accustomed to call collodion. CPi and CP2 were not respectively wholly insoluble and wholly soluble in ether-alcohol their compositions were approximate, and CP2 always contained a certain amount of material soluble in alcohol alone. A mixture of CPi and CP2 colloided with ether-alcohol was used for making pou-... 

Uses In place of potassium chlorate in percussion primer compositions, with the object of prodneing noncorrosive primers, P4. Also in pyrotechnic compositions, in blasting explosives, and in some componnd propellants. See Double-Base Powders, E. C. Powder, Poudre B. N., Tonite, Strontium Nitrate, F8.
