ABSTRACT:
The invention is directed at a composite material comprising a product of a combination of materials. The combination of materials comprises an inorganic filler comprised of ceramic cenospheres, a thermoplastic polymer and a coupling agent comprised of at least one fatty acid having at least 16 carbon atoms and at least one rosin acid having at least 16 carbon atoms. The combination may further comprise an organic filler comprised of cellulosic material and wherein the thermoplastic polymer has a melt temperature of less than the char temperature of the organic filler. The invention is further directed at a process for producing the composite material comprising the step of combining the components at a temperature of greater than or equal to the melt temperature of the thermoplastic polymer. Where the components include the organic filler, the process temperature is less than the char temperature of the organic filler.
