One weak aspect of synthetic polymer materials compared with steel and other metals is that these materials are combustible under certain conditions. Thus, the majority of polymer containing end products must pass some type of regulatory test to assure public safety from fire. Although halogenated flame retardants are highly effective for reducing heat release rates of commodity polymers, the future use of some of these retardants is becoming highly questionable in Europe and possibly worldwide. Therefore, new, highly effective flame retardants are urgently needed as a possible alternative to conventional halogenated flame retardants. The main objective of this research is to apply combined effects of a catalyst in a clay-based polymer nanocomposite to enhance formation of char from a resin to form a protective layer consisting of char enhanced clay network during burning.
