Abstract:
A rug gripper (10) for preventing the lateral movement of a rug (14) on a floor (16) comprising a continuous non-slip, non-adhesive foam layer having a top surface and a bottom surface. The top surface of the foam layer includes an adhesive layer for adhering the foam layer to the rug and the bottom surface of the foam layer engages the floor.
Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines atmungsaktiven mehrschichtigen Kunstleders mit einer Trägerschicht aus einem textilen Flächengebilde, mindestens einer auf die Trägerschicht aufgebrachten Zwischenschicht auf Basis eines zumindest teilweise offenzelligen Polyurethan-Schlagschaumes sowie einer auf die mindestens eine Zwischenschicht vollflächig aufgebrachten Deckschicht auf Basis eines Polyurethans, wobei in einem ersten Schritt die Deckschicht auf eine ablösbare Unterlage aufgebracht und verfestigt wird, nachfolgend die mindestens eine Zwischenschicht auf die Deckschicht aufgebracht und anschließend die Trägerschicht auf die mindestens eine Zwischenschicht aufgelegt wird und die Unterlage von der Deckschicht gelöst wird, wobei zur Ausbildung der Deckschicht eine wässrige aliphatische Polyurethandispersion in flüssiger Form auf die Unterlage aufgebracht wird und unmittelbar nach dem Aufbringen der Polyurethandispersion der Wassergehalt derselben durch Wärmezufuhr binnen so kurzer Zeit verdampft wird, dass eine verfilmungsfreie Trocknung der Polyurethandispersion auf der Unterlage unter Ausbildung der Deckschicht mit Mikroporen bewirkt wird. Es wird ferner auch ein entsprechendes atmungsaktives mehrschichtiges Kunstleder angegeben.

Abstract:
The present invention relates to a method of joining at least two parts by adhesion, said method comprising arrangement of a porous layer in the adhesive joint for taking up excess adhesive from the adhesive joint as such. The invention further relates to an element - including in particular a blade for a wind turbine - which is combined by adhesion of several parts, and wherein a porous layer is at least partially comprised in the adhesive joint between the parts and take up excess adhesive outside the adhesive joint. The porous layer may be of a mesh-like structure or may have the structure of a sponge and may furthermore be entirely or partially pre-impregnated with adhesive.
Abstract:
This invention provides air impermeable liquid-water resistant water-vapor-permeable composites that have enhanced water-vapor-permeable properties. The composites comprise: a layer of a microporous polymer that is water-vapor permeable and which is liquid water-resistant. This layer is in contact with an air-impermeable, liquid water resistant, polymer layer that is permeable to water-vapor molecules. A third layer of a microporous, water vapor permeable, hydrophilic polymer is present on the other side of the air-impermeable polymer layer.
Abstract:
A multilayer sheet material that is capable of being adhered to a foamed polymer core material is prepared from at least four layers, which are a first outer layer of a printable sheet material, an inner layer of a fibrous sheet material, an inner layer of an adhesive material, and a second outer layer of a weldable sheet material. Stiff foam polymer core articles, such as body boards, having detailed designs on them can be prepared by welding the multilayer sheet material to a foamed polymer core material.
Abstract:
Foaming of a resinous backing (2) to a glass sheet (1) is frustrated at the interface (3) with the glass by maintaining the glass sheet (1) cool during formation of the foam. The degree of foaming is nil at the interface (3) to effect a strong bond there, and increases progressively through the thickness of the foam body (2) away from the interface (3). The foam body (2) is backed by glass-fibre cloth (4) that is impregnated with the resin from which the foaming gas has been vented so as to bond the cloth (4) to the body (2) and to an outer aluminium foil (5). The glass sheet (3) may be a mirror, and may be replaced by a glass laminate (20; 23) that includes a fused-powder coating (22; 25) with or without an aluminium foil backing.
Abstract:
Large-surface panelling made of thermoplastic materials for the inside of motor vehicles or similar applications have a substrate made of polyolefinic particle foams lined with a decorative ply made of mainly polyolefinic polymers during the moulding process of the panelling. The decorative ply is composed of a multilayered knitted or woven fabric with knitted-in spacers preferably made of preferably polyolefinic polymer threads, has a decorative textile surface, its upper face is laminated with a decoratively designed foil, preferably based on olefinic polymers, or its back side is also laminated with a polyolefin foil.
