Pyrotechnic Chemistry

Pyrotechnic Chemical Compositions

Pyrotechnic chemical compositions contain an oxidizer component and a fuel component and are used in a wide range of applications: Delay Elements, Flares, Tracers, Igniters, Impulse Cartridges and Primers.

Since pyrotechnic compositions contain an oxidizer component, they do not rely on oxygen from external sources to sustain the reaction.

Pyrotechnic composition particles can be grains or flakes. Generally, the higher the surface area of the particles, the higher the reaction rate and burning speed. For some purposes, binders are used to turn the powder into a solid material.

IPI provides our exclusive virgin Kraft paper surface-coated with nitrocellulose lacquer using state-of-the-art solvent coating
process yielding the highest quality sealing paper in the industry. IPI is recognized as the global leader of sealing paper in
accordance with MIL-P-60169B Type I and Type II.

IPI coated sealing paper provides the Primer manufacturer with uniform coating, superior thickness control and high tensile
properties to eliminate slipped foils realizing high productivity yield and throughput.

IPI Sealing Paper is available in White, Red and Green colors. Custom roll widths and lengths are available.

Used mainly in small arms ammunition for tracking, spotting, incendiary fire and fire control purposes.

Delay elements consist of a composition of chemicals (typically a fuel, an oxidizer and an additive) that burn at a slow, constant rate, encapsulated in a small-diameter tube inserted inside the ignition train. This provides a delayed ignition in fuze-based explosive trains, cartridge-actuated devices and other devices.

Delay time accuracy depends on the purity and precise particle size distribution of the chemicals in the composition, along with the exact ratio of materials in the mixture.
