Abstract

Many pyrotechnics contain binders, such as nitrocellulose, Viton, and other plastics and elastomers. Most pyrotechnics are prepared by the dispersion of fuel/oxidizer ingredients in a liquid solution, which are then mixed well to form pyrotechnics. The thermal decomposition behavior of a binder is very important to pyrotechnics in a polymer. In this work, the thermal decomposition behaviors of three fluoropolymers have been investigated with differential thermal analysis/thermogravimetry and differential scanning calorimetry. The parameters concerning decomposition have been evaluated with a nonisothermal technique, and a suitable binder is suggested for the Zr/KClO4 priming mixture. © 2005 Wiley Periodicals, Inc.
