Flammability Studies of Polymer Layered Silicate (Clay) Nanocomposites (NISTIR 6242)

In the pursuit of improved approaches to fire retarding polymers a wide variety of concerns must be addressed, in addition to the flammability issues. First, the low cost of commodity polymers requires that the fire retardant (FR) approach also be of low cost. This limits one primarily to additive type approaches. Second, these additives must be easily processed with the polymer. Finally, any additive must not excessively degrade the other performance properties of the polymer, and must not create environmental problemsin terms of recycling or disposal of the end product. Polymer layered silicate (PLS) nanocomposites are materials that may partially fulfill the above requirements for high performance flame retardant products.
