A floor may include a substrate having a top side and a bottom side. A top layer may be provided on the substrate. The top layer may consist of a printed thermoplastic film and a thermoplastic transparent or translucent layer provided on the printed thermoplastic film. The top layer may be directly adhered to the substrate by heat welding the printed thermoplastic film and the top side of the substrate, in the absence of a glue layer. The substrate may be a synthetic material board including a filler. The substrate at least at two opposite edges may include coupling means provided in the synthetic material board. The thermoplastic transparent or translucent layer may be provided with a structure.

Calibration method for machines for the production of segmented extruded products comprising the steps of: activating an extrusion process according to a plurality of operating parameters suitable for producing a segmented extruded product having at least one segmentation portion (6); injecting a marker at the segmentation portion (6) during its extrusion; detecting a plurality of characterizing parameters of the marker and/or of the segmentation portion (6), by selecting at least one of spatial distribution of the segmentation portion (6) and axial and/or radial position of the segmentation portion (6); selecting at least one operating parameter according to at least one of the detected characterizing parameters, so as to modify spatial distributions and/or axial and/or radial positions of the segmentation portion (6).

Coextended polymeric article comprising a layer comprising first and second opposed major surfaces, wherein a plurality of attached projection pairs comprising first and second projections extend from only the first major surface (i.e., the second major surface is free of any projections), wherein each first projection has at least first and second opposed sides and a height from the first major surface to a distal end, wherein each first projection has at least first and second opposed sides and a height from the first major surface to a distal end. Uses for coextruded polymeric articles described herein include adhesive articles and household cleaning products (e.g., a mop, a duster, a brush, a cleaning cloth, or a lint roller).

A structure has a substrate, a first material on the substrate, the first material having a binder and a first active material, periodically located trapezoidal voids that only partially extend from a top of the first active material towards the substrate, and an electrolyte material filling the trapezoidal voids.

A polyester film and a method for producing the same are provided. The polyester film includes a heat resistant layer. The heat resistant layer includes a high temperature resistant resin material and a polyester resin material. The high temperature resistant resin material and the polyester resin material are melted and kneaded with each other via a twin screw granulator. The twin-screw granulator has a twin-screw temperature between 250 C. and 320 C., and the twin-screw granulator has a twin-screw rotation speed between 300 rpm and 800 rpm, so that the high temperature resistant resin material is dispersed in the polyester resin material with a particle size of between 50 nm and 200 nm.
