Process for manufacturing a floor covering having a foamed backing formed from recycled polymeric material

Image Number 12 for United States Patent #6860953.

The present invention provides a cushioned floor covering having a backing material formed from waste polymeric material and a blowing agent wherein the blowing agent may be activated either before or after the backing material is adhered to the floor covering. The waste polymeric material includes from about 0 to 40 percent aliphatic polyamide material and is granulated, densified and extruded at a temperature that does not exceed the temperature at which the blowing agent would be activated.
