The present invention provides a foamed polyvinyl chloride product and method of making the same. The foamed polyvinyl chloride product includes at least one under layer and at least one surface layer. The under layer comprises 100 parts by weight of polyvinyl chloride resin, 75-95 parts by weight of plasticizer, 10-30 parts by weight of filler, 4-6 parts by weight of power heat stabilizer, and 5-15 parts by weight of foaming agent. The surface layer comprises 100 parts by weight of polyvinyl chloride resin, 75-95 parts by weight of plasticizer, 10-30 parts by weight of filler, 4-6 parts by weight of liquid heat stabilizer, 0.5 to 30 parts by weight of the coloring sand, 5-15 parts by weight of foaming agent and 0-50 parts by weight of the flame retardant. By adjusting the types and dosages of heat stabilizers, the foamed polyvinyl chloride product can be mixed through planetary extruders, and has good gelation and foaming property. |
