Fire and Polymers IV


The combination of metal hydroxides (aluminum or magnesium) with an organically-modified clay has been studied as a potential fire retardant system for polypropylene. The combination of polypropylene with 5% inorganic clay and 20% of the metal hydroxide gives an 80% reduction in the peak heat release rate, which is the same as what is obtained when 40% of the hydroxide is used alone. This means that more polymer can be used, which could be an advantage in some situations.
