Abstract

A plasticized pyrotechnic material can be easily portioned and formed or molded into a desired shape and burns at a high temperature (>2000° C.) but does not detonate. The plasticized pyrotechnic material may preferably include a combination of about 70-99% by weight of a pyrotechnic composition and about 1-30% by weight of a plasticizer composition comprising various low to mid molecular weight polyisobutylenes. The pyrotechnic material comprises inorganic oxidizers (e.g. metal oxides, oxohalide salts, nitrates, nitrites, chlorates/perchlorates) and metal or metal oxides powders mixed intimately. The plasticizer may include a small amount of a fluoropolymer, such as polytetrafluoroethylene (PTFE) and may also include up to 1-2% by weight of a processed oil, such as a mineral oil or motor oil. Some embodiments may also include a biocide precursor molecule.
