NOVELTY - Polyvinyl chloride foam comprises 100 pts. wt. polyvinyl chloride resin, graphene and mixed liquid comprising 9-10 pts. wt. foaming agent, 50-69 pts. wt. plasticizer, 20-25 pts. wt. grease, 4-5 pts. wt. zinc oxide, 4-5 pts. wt. stearic acid and 350 pts. wt. calcium carbonate. The volume ratio of the graphene and the mixed liquid is 5-55:45-95. USE - Used as polyvinyl chloride foam. ADVANTAGE - The method reduces electromagnetic radiation while enhancing mechanical property of product. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing polyvinyl chloride foam, comprising adding polyvinyl chloride resin into an extruder for melting, injecting graphene and mixed liquid into the extruder, evenly mixing the mixture by the rotation of the extrusion screw, die extruding, and controlling the temperature to obtain the polyvinyl chloride foam.
