摘要:
Disclosed are compositions of ethylene acid copolymers and polyamides that are useful for fabricating films, sheets and molded articles for scuff and scratch resistant material and their application as decorative and protective films, comprising (1) from about 30 to about 65 weight % of a polyamide; and (2) from about 70 to about 35 weight % of a copolymer of (a) ethylene; (b) from about 5 weight % to about 15 weight % of an &agr;,ß unsaturated C?3#191-C?8#191 carboxylic acid; (c) from about 0.5 weight % to about 12 weight % of at least one comonomer that is an ethylenically unsaturated dicarboxylic acid; and (d) from 0 weight % to about 30 weight % of monomers selected from alkyl acrylate and alkyl methacrylate, wherein the alkyl groups have from one to twelve carbon atoms; at least partially neutralized by one or more alkali metal, transition metal, or alkaline earth metal cations. Articles prepared from these compositions, such as films, show high toughness, good mechanical properties, excellent scratch and scuff resistance and, most importantly, good optical properties. More particularly, the compositions of ethylene copolymers and polyamides of the present invention can be used as protective coatings or layers on scuff- and scratch-exposed objects.

An aspect of the invention relates to a surface cover for a body which can be brought into contact with a liquid, comprising: a layer which at least partly contains gas and which is designed and arranged such that at least some sections of a layer face facing the liquid contacts the liquid; a gas-permeable layer which is arranged on the gas-containing layer on a face that faces the body and is opposite the face facing the liquid or which is integrally formed with the gas-containing layer; and a gas-supplying device which is connected to the gas-permeable layer such that gas can flow from the gas-supplying device to the gas-containing layer through the gas-permeable layer. The invention also relates to an arrangement and a use.
摘要:
A laminated mat for the display of information on floor or road surfaces, on walls or objects and for use indoors and outdoors is composed of a print (3) on a print layer (4), e.g. a tarpaulin cloth (4), which print layer may be a polyester, a rubber, a PVC layer, a vinyl layer or a fabric, or mixtures of polyester with rubber, PVC or fabric. A protective layer (2), which may be formed by polyurethane, is laminated on the upper side of the print layer. In particular for floor or road surfaces where the mat is subjected to mechanical impacts, a frictional, non-skid or wear-resistant layer (1) is laminated on the protective layer. An adhesive (5) is applied below the tarpaulin cloth, said adhesive securing a non-skid layer (6) which is adapted to the surfaces on which the mat may conceivably be used.

A refurbishable covering (14) is provided for the surface of an article (10) which, in use, carries decorative material (20) on the inner surface (16), the covering (14) being attached to the surface of article (10) and having a refurbishable outer surface (18) from which marks or scratches can be removed, without affecting the decorative appearance imparted by decorative material (20).
摘要:
Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packets pairs. Some of the polymer layers, including at least one embedded layer, comprise an antimicrobial agent, and these layers may be positioned at the front of each layer packet. After the antimicrobial layer of one layer packet has been used, the packet can be peeled away to expose a pristine antimicrobial layer of the next layer packet. The antimicrobial agent may be organic.

Ein Aspekt betrifft eine Oberflächenabdeckung für einen mit einer Flüssigkeit kontaktierbaren Körper umfassend: eine zumindest partiell gashaltende Schicht, welche derart auslegt und angeordnet ist, um mit einer flüssigkeitszugewandten Seite zumindest bereichsweise mit der Flüssigkeit zu kontaktieren; eine gasdurchlässige Lage, welche an einer der flüssigkeitszugewandten Seite gegenüberliegenden körperzugewandten Seite an der gashaltenden Schicht angeordnet ist oder welche mit der gashaltenden Schicht integral ausgebildet ist; eine Gaszufuhreinrichtung, welche mit der gasdurchlässigen Lage verbunden ist, so daß Gas von der Gaszufuhreinrichtung durch die gasdurchlässige Lage zur gashaltenden Schicht strömen kann, sowie eine Anordnung und eine Verwendung.
摘要:
Manufacturing methods and systems providing continuous rolls of polyvinyl materials printable on one side and "sticky"- adherable on the other side. Such continuous rolls may be thereafter cut into sizes appropriate for signs, bumper stickers, and other information and/or design objects which are affixable to appropriate surfaces for a variety of advertising and/or design uses.

The article is a material that is acoustically and thermally functional, thermally insulative, easy to handle and fabricate, easy to slide into wall channels or place into the wall, light weight, non-shedding, non-toxic, mold/mildew resistant, non- delaminating, resistant to tearing/breaking, has a high R-value, or a combination thereof.
摘要:
A method for making a polymeric part having an anti-graffiti property is disclosed. The method includes formulating a first mixture of a polymer and a hydrocarbon mixture, forming a substantially planar sheet of the first mixture, formulating a second mixture of a mineral oil and a wax, coating a surface of a forming mold with the second mixture of a mineral oil and a wax, and thermoforming the substantially planar sheet to form the polymeric part using the forming mold coated with the second mixture of mineral oil and wax.
摘要:
This invention relates to a method of repairing one or both sides of an optically damaged substrate such as rigid glass or plastic window, signage or displays. The invention also relates to the repaired substrates. This invention also relates to an article comprising a transparent stack of sheets that may be applied, for example, to protect said repaired substrates such as glass or plastic windows, signage or displays. A topmost sheet can be peeled away after it is damaged to reveal an undamaged sheet below. The invention also relates to the protected substrates and a method of protecting substrates such as glass or plastic windows, signage and displays from vandalism or other surface damage by adhering the stack of sheets to the substrate to be protected and subsequently pulling a topmost sheet away from the stack after it becomes damaged.
