A HEAT FOAMABLE PLASTISOL MIX CONSISTING ESSENTIALLY OF (A) A FINELY DIVIDED PARTICULATE RESIN SELECTED FROM THE GROUP CONSISTING OF VINYL CHLORIDE HOMOPOLYMERS AND COPOLYMERS; (B) A PLASTICIZING AMOUNT OF A PLASTICIZER FOR (A); (C) AN EFFECTIVE AMOUNT OF AN ALKALI METAL PERBORATE CAPABLE OF RELEASING SUFFICIENT OXYGEN AT TEMPERATURES ABOVE ABOUT 200*F. TO FOAM SAID PLASTISOL AND EXPAND THE SAME TO AT LEAST ABOUT 3 TIMES ITS ORIGINAL VOLUME; (D) AN EFFECTIVE AMOUNT OF AN ACIDIC COMPONENT HAVING AN ACIDITY AS TO (C) SUFFICIENT TO FACILITATE THE DECOMPOSITION THEREOF; AND (E) AN EFFECTIVE AMOUNT OF A FINELY DIVIDED SOLID PARTICULATE COMPONENT WHICH FIRST ADSORBS OXYGEN AND CONTROLLABLY RELEASES THE ADSORBED OXYGEN AT THE FOAMING TEMPERATURE OF THE PLASTISOL AT A RATE WHICH PRODUCES A STABLE CELLULAR FOAM.
