Abstract

A polymer composite material includes a blend of one or more thermoplastic polymers and one or more bio-based flame retardant additives, wherein the one or more bio-based flame retardant additives are present in an amount of 35 to 100 parts per 100 parts by weight of the one or more thermo-plastic polymers. A method of forming the polymer composite material includes: blending the one or more thermoplastic polymers and the one or more bio-based flame retardant additives together at a temperature between 140° C. and 230° C. to form the polymer composite material; forming an article from the polymer composite material; and cooling the formed article.
