Floor covering and films for use therewith
View Patent ↗A film for application to the upper surface of a floor covering comprising: (a) a blend of an acrylic resin and a fluoropolymer resin; and, optionally (b) anti-slip particles wherein the film comprises two or more layers. A method of forming the floor covering is also disclosed.
1. A clear, stain-resistant film for application to the upper surface of a floor covering comprising:
(a) a co-extruded blend of an acrylic resin and a fluoropolymer resin; and
(b) 4% by weight of inorganic anti-slip particles comprising glass bubbles,
wherein the film comprises at least a first upper layer and a second lower layer,
wherein the first layer is a brittle layer and the second layer is a stronger layer,
wherein the film is free of volatile organic compounds,
wherein the first layer includes about 40 to 55% fluoropolymer and the second layer includes about 55 to 70% fluoropolymer, and
wherein the film has thickness of from about 30 μm to 250 μm.
2. A film according to claim 1 wherein a lower layer of the film does not include anti-slip particles.
3. A film according to claim 1 wherein the acrylic resin is an alkyl methacrylate or an alkyl acrylate.
4. A film according to claim 1 wherein the fluoropolymer is selected from the group consisting of homo-, co- and ter-polymers of vinylidene fluoride, tetrafluoroethylene, hexafluoropropylene, vinyl fluoride and ECTFE.
5. A film according to claim 1 , wherein the first layer of the film has a different composition than the second layer of the film.
6. A film according to claim 1 , having a thickness of from about 50 μm to about 100 μm.
7. A film according to claim 1 , having a thickness of from about 60 μm to about 80 μm.
