Abstract
Disclosed are polyvinyl chloride resinous compositions containing cellular fillers such as Silus Balloon and pearlite and molded products prepared by subjecting the compositions to heating at an increased pressure. The molded products may be combined with a core layer such as a non-woven fabric and a victria lawn, a foamed layer such as PVC paste resinous foam, a surface layer such as a non-foamed synthetic resin and molded into laminated sheet products. Those are made lighter and superior in soundproof and adiabatic effects, bending strength, dry touchness, water resistance, dimensional stability, cold resistance and the like so that structural materials such as floor coverings and the like are supplied more advantageously as compared with conventional ones.
