The dependence of sensitivity`s indicators to impact from composition for mixes of ultradispersed ammonium perchlorate (UAP) with polytetrafluorethylene (PTFE) was defined by method of critical energy. It is shown that in a wide range of teflon1s content the critical energy of initiation of mixes isn’t differentiate from the sensitivity of basic component (UAP). It can be explained by the influence on process of initiation of explosion of many competing factors, in particular, diluting UAP combustible active fluorine-contenting component, position of a maximum of heat of explosion at equimolar content of components, increase in dynamic viscosity of mixes at teflon contents. Calculations of critical parameters of explosion initiation depending on composition of mixes are executed on the basis of representations about chemical interaction of components in the center of explosion initiation.
