Abstract
The present disclosure relates to pyrophoric pellets that break apart into individual particulates or agglomerates when exposed to air and emit infrared radiation. The pyrophoric pellets include: (a) about 35 to about 95 wt. % of pyrophoric particles; (b) about 0.05 to about 30 wt. % of one or more thermally expandable particles; (c) about 1 to about 40 wt. % of one or more additives that modify IR signature; and (d) optionally, one or more additives that produce smoke at a temperature of 150° C. or greater. The pyrophoric pellets are particularly useful as countermeasures to protect against incoming missiles.
