  • FOAMED SURFACE COVERING WITH COHERENT LAYER
    Publication number: 20160332419
    Abstract: Embodiments of a new foamed surface covering are disclosed, wherein a primary layer of polymeric foam features at least one coherent layer consisting of a water-resistant blend of styrene-maleic anhydride and acrylic resin. The coherent layer facilitates the secured and reusable application of the surface covering after repeated washings.

  • Perforated nonslip non-adhesive surface covering
    Patent number: 9248314
    Abstract: The present disclosure relates to removable, nonslip, non-adhesive coverings which are used as shelf, drawer or storage liners. In particular, the covering sheet features an improved composite material having a top decorative layer of flocked polymeric film combined to a continuous bottom layer of unsupported foam. The structure of the multilayered composite material facilitates the convenient hand tearing of the sheet to size through a grid of perforations that are obscured by a fine coating of natural or synthetic fibers.

  • PERFORATED MONOLAYER, NONSLIP, NON-ADHESIVE SURFACE COVERING
    Publication number: 20130236691
    Abstract: Embodiments of a new non-slip, non-adhesive surface covering are disclosed, wherein a single layer of unsupported polymeric foam features a grid of perforations to facilitate the convenient hand tearing of the sheet to size. The unsupported foam includes an improved polymeric formulation to augment the tensile strength properties of the material. The enhanced structure of the polymeric foam resists the unintended separation of the incised perforations upon installation of the surface covering.
