A method for nano-depth surface activation of a PTFE-based membrane and relates to the technical field of polymer composites is disclosed. The method comprises the following steps: covering a functional surface of a PTFE-based nano functional composite membrane, performing surface activation treatment on a single surface of the membrane to which a bonding adhesive is applied, and migrating and complexing a high-toughness cold bonding adhesive tape on the membrane surface, with an activated structure layer, of the PTFE-based nano functional composite membrane through a mechanical adhesive applying device to form an adhesive-membrane complex. An extremely strong affinity and a high-strength bonding performance are generated between the membrane and the adhesive, and the adhesive-membrane complex is formed. Integration of membrane/adhesive bonding complexing, membrane/membrane bonding complexing and membrane/adhesive layer bonding is realized.

A cohesive sealant layer directly adhered to two adjacent layers. One adjacent layer comprising predominately polyester. The other adjacent layer comprising predominately polyethylene polymers. The cohesive sealant layer being a blend including polyester and at least a compatibilizer such that the cohesive sealant layer has an opening strength of between 0.4 and 3.4 lb-f/in or between 0.9 and 3.0 lb-f/in measured according to ASTM F88 with a crosshead speed of 10 inches per minute, using a 1-inch wide sample. The cohesive sealant layer having a bond strength to both of the adjacent layers which is greater than the opening strength resulting in in a continuous portion of the cohesive sealant layer remaining adhered to the two adjacent layers when subjected to a force greater than the opening strength.

Proposed are a method of manufacturing a polarizing film and the polarizing film thereto that is not harmful to the human body by making the surface of a PC film hydrophilic, and laminating it with a PVA film using water-based adhesive on the surface of the hydrophilic PC film, in manufacturing the polarizing film by laminating a polycarbonate (PC: polyvinyl alcohol) film and a polyvinyl alcohol (PVA: polyvinyl alcohol) film constituting the polarizing film.

A composite construction, such as, in particular, a composite plate having a sandwich-type construction, has two outer layers which are mutually opposed in parallel and a foam material completely filling the space between the outer layers at least in some regions. The outer layers are interconnected by means of spacers, and the spacers are connected to the outer layers via a cured plastics material.

This easily peelable absorption film is provided with an absorption film that contains a thermoplastic resin and an absorbing agent, and an easy-peel layer that is layered directly on one surface of the absorption film, wherein: the absorbing agent content is 20 mass % or more with reference to the mass of the entire absorption film; and when the easy-peel layer of the easily peelable absorption film is heat-sealed to another resin and the easily peelable absorption film is peeled from the other resin, the easy-peel layer agglomerates and peels away.

Disclosed herein is a method of manufacturing an improved cover board product with a panel. In some embodiments, the method includes preparing fragments into an assembly; mixing the fragments and an adhesive into a blended core furnish; applying the adhesive to a top side of a bottom layer fabric in the assembly; forming a core mat of the blended core furnish on top of the adhesive; applying the adhesive to a top side of the core mat; applying a surface layer fabric on the top side of the adhesive; pressing the assembly; and cutting and trimming the assembly to form panels.

A multilayer laminate film assembly is provided, which includes at least two multilayer substrate films, each substrate film having at least a first outer layer and a second outer layer, and wherein the at least two multilayer substrate films each include at least two layers of a different class of material. In the laminate film assembly, the at least two substrate films are laminated together, preferably wherein the class of material of the first outer layer differs from the class of material of the second outer layer. The multilayer substrate films are from the same type of substrate. A standing pouch is further provided which includes a front panel, a back panel, and a bottom panel, wherein all panels are from the multilayer laminate film.

The present invention has an object of providing an ethylene/α-olefin/non-conjugated polyene copolymer composition excellent in the adhesive strength with a layer of a saponified ethylene/vinyl acetate copolymer; and the present invention relates to a laminate comprising a layer of a copolymer composition comprising 100 parts by mass of an ethylene/α-olefin/non-conjugated polyene copolymer (A) and one or more additives selected from the following (1) to (3), and a layer of the saponified ethylene/vinyl acetate copolymer (B). (1) 1.7 to 20 parts by mass of dicumyl peroxide and 2 to 20 parts by mass of a metal oxide; (2) 20 to 120 parts by mass of a hydrophilic fumed silica; and (3) 5 to 50 parts by mass of an ethylene/vinyl acetate copolymer (B).

A thermoplastic roofing membrane comprising a planar thermoplastic sheet, optionally having more than one layer, where at least one layer of the membrane includes an ethylene-based olefinic block copolymer, and where the sheet is characterized by a storage modulus of less than 450 MPa at 0° C.

The present invention relates to a method for forming a multilayer plastic sheet material for floor and/or wall panels, wherein a first polymer mass comprising a chemically foamed PVC is melted under pressure and is forced through an extruder head at a well-defined discharge rate as a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed, which is propelled towards two or more rolls of a rolling mill, which processes the multilayer plastic strand to a sheet of a defined thickness and where one of the rolls will apply a three-dimensional structure in the top layer. This sheet will then be led away by a discharge device to a sawing device to be cut off to the desired length and width and finally, in a subsequent production step, as multilayer plank-shaped elements, will be provided with coupling parts on two opposite edges so that several of said plank-shaped elements are couplable together.
