Abstract

PURPOSE: To obtain a PVC foam having an improved degree of foaming, by mechanically foaming a PVC paste dispersion containing a substance having poor compatibility with a plasticizer and being volatile at temperatures below the gelation temperature, and then heating and melting the foamed dispersion.
CONSTITUTION: A plastisol is prepared by adding to material resin powder consisting mainly of polyvinyl chloride resin fine particles, a plasticizer, a foam stabilizer, 0W20pts.wt. pref., 1W10pts.wt. per 100pts.wt. of material resin, of a substance such as water, which has poor compatibility with the plasticizer and which is volatile at temperatures below the gelation temperature, and optionally fillers, a pigment and a heat stabilizer, and uniformly mixing the resulting mixture in a mill. The plastisol thus prepared is uniformly mixed together with compressed air in a mixer such as Orks mixer to obtain a plastisol containing fine bubbles of air. Then, the plastisol, which may be in the form of coating or casting, is heated and allowed to gel to produce a foam having uniform fine cellular structure.
