ABSTRACT:
The instant invention is directed to a novel process for the production of bonded foam, and particularly polyurethane foam scrap. The process allows for the production of a high quality rebonded product. Significant improvements are seen in the quality of the product, reduction in density, reduction in scrap loss, elimination of density variations in the molded product and overall product consistency.
