  • Patent number: 6703447
    Abstract: A polymeric film and method for making the film. Mixing a structural material with a secondary material to form a unitary mixture prior to processing forms the film. For a printable film, the secondary material is a printable material. The unitary mixture is extruded and heated so as to cause the printable material to bloom to the surface of the mixture. The result is a film that is stiffer and that lays flatter than prior multi-layered films that were prone to curling. The rollers used to stretch the film during this heat-setting stage are preferably very smooth so as to enhance the transverse-direction strength and stiffness of the film. In another embodiment of the invention, the secondary material is a clarity-enhancing material that may be styrene-ethylene-butadiene-styrene block copolymer. The blend combination is a suitable replacement for polyvinyl chloride films in that it is soft, conformable, flexible and clear.

  • Publication number: 20030212211
    Abstract: Disclosed is a product and process for a substantially halogen-free thermoplastic elastomer. The thermoplastic elastomer can be incorporated into a decorative surface covering as a binder with the addition of an optional filler. The substantially halogen-free thermoplastic comprises the combination of a dynamically vulcanized blend of epoxidized natural rubber (ENR), ionomers and a diluent polymer such as ethylene vinyl acetate (EVA). The combination produces a pliable and flexible flooring product.
