Provided is a water absorption treatment material and a method for manufacturing the same, according to which a clump can be formed after use without incurring a decrease in water absorptivity. A water absorption treatment material includes a granular core portion and an embedded portion. A recessed portion is formed on the surface of the granular core portion. The embedded portion is provided in the recessed portion of the granular core portion. The embedded portion contains an adhesive material.

A catheter is made by coextruding first and second molten polymers, wherein the second molten polymer forms a flexible inner core and the first molten polymer forms exactly two bands on opposite sides of the inner core. The inner core is braided, and a third molten polymer extruded onto the braid to form a flexible jacket that encloses the braid, the bands and the inner core. The bands are more rigid than the inner core, and they provide preferential in-plane bending.

An extrusion apparatus for extruding an edge guard for flooring products or the like, which apparatus includes an extrusion die for simultaneously extruding at least two components simultaneously, such as stripes of alternating colors for a visible part of the edge guard, to render the striped part of the edge guard visible to persons crossing the edge guard.

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.
