Composition based on Potassium Perchlorate tends to be less sensitive than those based on chlorates. Perchlorates can be used with sulfur and sulfides. For these reasons, it is much preferred above chlorates. This is a strong oxidizer although it usually reacts very slowly with organic substances. Perchlorate is a common oxidizer used in fireworks, ammunition percussion caps, explosive primers, and is used variously in propellants, flash compositions, stars, and sparklers.
According to the certificate of analysis 99% passes a 325 mesh screen, purity is at 99.5% or better. This means it’s ready to go out of the container with no further processing needed.
This Potassium Perchlorate contains a small amount of Cabosil to help minimize clumping and keep the mixture free-flowing.
Perchlorate is toxic, can be absorbed through the skin and breathing protection should be worn when handling fine powder.
