Abstract
Abstract A composition comprising an intimate bonded mixture of (a) 30-90 parts by weight of a particulate reinforcement filler formed of the pyrolysis or incineration residue of industrial or municipal solid waste products, and (b) 10-70 parts by weight of a resinous thermosetting (e.g., polyester or epoxy) or thermoplastic (e.g., nylon) adhesive polymer. The filler comprises a combination of silica and alumina and for pyrolysis residue, carbon. The individual particles are characterized by non-porous structure and irregular rough shapes, having a heterogeneous distribution and a size less than 50 microns.
