Method of producing molded products from stripped roofing material

摘要

A method of converting stripped roofing material into a useful product comprising feeding roofing material removed during repair or reroofing of a building roof into a shredder introducing particles of material from said shredder together with particles of thermoplastic material and a particulate filler material into a high intensity mixer to form a batch of material to be mixed, intensely mixing said batch of material to produce a heated mass of hot particles of roofing material and filler material coated with molten thermoplastic, then molding said heated mass under pressure into a desired end product. The invention also includes products produced utilizing said stripped roofing material.
