Abstract

A process for the manufacture of reconstituted polyvinyl chloride foam from pulverized foam particles, characterized in that PVC foam particles having an average particle size between 3 and 15 mm, are combined with a bonding agent polyurethane precursor derived from a methylene polyisocyanate the resulting mass is molded and the bonding agent is cured.
