Abstract: The invention relates to a film for use in a resilient floor covering, wherein the film comprises (a) a first layer and (b) a second layer and wherein the first layer has a Shore D hardness of 60 to 80 at 20° C. and the second layer has a Shore D hardness of 40 to 65 at 20° C. Also provided is a composite laminate floor covering comprising the film of the invention. Also provided is a floor tile comprising the film of the invention.

Abstract: The present invention relates to a backing film for a resilient floor covering comprising (a) a first layer and (b) a second layer, wherein the first layer contains a first filler in an amount of from 10 to 80% by weight and the second layer contains a second filler in an amount of from 10 to 80% by weight and wherein the first filler is a platelet type filler.

Abstract: A plastics floor covering (1) included a plurality of discrete plastics components (2, 3, 4) each having an upper surface and a lower surface (lower surface shown). The discrete components (2, 3, 4) are assembled together to form a predetermined design and are held in the assembled position to form a unitary floor covering (1) by at least one portion of a joining film (14) secured to the lower surface of each discrete component (2, 3, 4). The joining film (14) spans at least the edges of neighboring discrete components (2, 3, 4) and is coated with a thermally labile polymeric coupling agent. The joining film (14) is perforated in a preferred embodiment of the invention.

Abstract: A backing film for incorporation as a backing layer in a resilient floor covering or a floor tile having at least two laminae and a method for making such a backing layer whereby wastage is reduced when the color of the upper lamina is changed. Where there are two backing films having two or three laminae making up the backing layer the intermediately colored film resulting from a change in the color of the upper lamina can be utilized without further processing on the second backing film where color is not essential. Where there are three laminae making up a backing film the desired color is introduced and established in the bottom lamina before the supply of the original color to the upper lamina is stopped. The film can then be turned over for use with the former bottom lamina becoming the upper lamina.

Abstract: A thermoplastic solid backing film manufactured by the co-extrusion of three polymer compositions wherein die-lip build up is avoided by adjusting the amount of filler present in each polymer composition. The first and third polymer compositions are such that substantially no die-lip build up occurs when these compositions are extruded through a die however the second polymer composition is such that there would be substantial die-lip build up if it was extruded adjacent a die-lip. The presence of the first and third polymer compositions prevents the second polymer composition from contacting the die-lip during manufacture of the backing film. The thermoplastic solid backing film can be incorporated in a resilient floor covering and in floor tiles.

Abstract: A plastics tile (9) is made up of a plurality of discrete plastics pieces (10, 11, 12) which are shaped relative to each other and assembled together to abut edge to edge in lower regions of the pieces and form a recess above each mutually abutting edge of abutting pieces in upper regions of the pieces. The pieces are joined together along said mutually abutting edges below the recesses to form a unitary tile.

Abstract: Resilient floor coverings are disclosed wherein the wear layer is a polymer composition, prepared from an ionomer resin and a polyfunctional olefinic compound, such as a polyfunctional acrylate. These floor coverings have good visual appearance and good burn, abrasion and stain resistance.

Abstract: Flexible vinyl floor coverings in which the wear layer comprises a blend of PVC, simple ester plasticizer and thermoplastic urethane polymer have improved anti-slip characteristics and good resistance to staining, abrasion and scratching. The urethane polymer is preferably an aliphatic polyester polyurethane, and it is preferably present in an amount of 5 to 40 parts by weight per 100 parts PVC resin.
