  • Patent number: 4307200
    Abstract: A composite foamed material and a process for the production thereof are disclosed herein, the process comprising premixing expandable or expanded polystyrene beads, a binder and fragments of resilient, open-celled neoprene. The materials are combined in the proportions of about 4-15% polystyrene beads, about 6-25% binder and about 60-90% open-celled neoprene. The combined materials are preferably compressed to a density of about 5-30 lbs. per cubic foot, more preferably 5-17 lbs. per cubic foot, and steam is applied to the compressed materials to cure the binder, and in certain embodiments to expand the polystyrene beads, thereby producing the desired composite foamed material.
    Type: Grant
