Pressure cartridges, Igniters, Initiators and Squibs

Pressure cartridges, Igniters, Initiators and Squibs, fall into the same general category. Functionally, they each convert a relatively low electrical (or mechanical) input into a higher energy output. Squibs and pressure cartridges are the heart of all of our electro-explosive devices and are basic to the design of all of our products. They are used as a heat or flame producing transducer to initiate a main propelling charge.   Squibs and Cartridges are used to pyrotechnically generate high-pressure gas and/or heat, and as such can be used as pressure sources or ignition sources. Schematically, squibs and cartridges are very similar. The practical difference is the squibs are generally of simpler construction, typically built around a "plug" of synthetic material. Cartridges may contain squibs, or more commonly, be built around a hermetic glass-to-metal seal instead. The result is that squibs are generally more economical, where glass-sealed cartridges are typically more rugged and better suited to higher-pressure applications.

Applications: Power source for piston devices, i.e. Actuators, Cutters, Puncture Devices. Power source for larger Pyrotechnic/Explosive devices. Pressure source to over-pressure/rupture closure disks on Stored Gas Systems. Performance: 50 psi in 5cc volume to beyond 10,000 PSI in 10 in3. Operating Temperatures of -65?F. to 420?F. (-54?C. to 215?C.) Electric Initiation from AC, DC, Capacitive Discharge. Percussion Initiation.
