Abstract:
Multi-layer composite structures offer improved weatherability and adhesion to fiber-reinforced plastic substrates when compared to structures now available. These composites have an outer layer made from a polyacrylate, a second layer made from an acrylonitrile-styrene-acrylate rubber terpolymer; a third layer made from an ABS polymer; and optionally a fourth layer made from a polyacrylate. The layers include one or more layers having an improvement selected from among: (a) the improvement wherein the second layer is made from an acrylate-modified acrylonitrile-styrene-acrylate rubber terpolymer; (b) the improvement wherein the third layer is a modified ABS that further includes a polymer modifier that decreases the softening of the ABS on contact with styrene, and an acrylonitrile-styrene-acrylate rubber terpolymer; and (c) the improvement wherein the fourth layer is present and is a polyacrylate. This composite can be applied to a fiber-reinforced plastic substrate such as fiberglass as a coating.
Abstract:
The invention relates to composite molded articles having a smooth, attractive thermoplastic surface. The invention also relates to a method having improved efficiency and reduced emission of hazardous air pollutants for making composite molded articles comprising a composite fiber reinforcement, thermosetting resin material having a thermoplastic exterior layer. The method comprises the steps of: (a) placing in a spaced apart relationship a first mold half comprising a first shaped ,mold membrane (5) and a second mold half (3) comprising a second shaped mold membrane (7) wherein the first and second shaped mold membranes define a mold plenum when brought together to mold articles; (b) placing a thermoplastic sheet (25) in the mold plenum wherein the shape of the thermoplastic sheet substantially conforms to the shape of the mold membrane; (c) placing reinforcement material (33) in the mold plenum; (d) closing the first and second mold halves such that the thermoplastic sheet.
Abstract:
An automotive trim part (18) comprising a pigmented transparent layer (32) overlying an intermediate bright film layer (30). The intermediate bright film layer (30) overlies a thermoplastic olefin layer (26). The thermoplastic olefin layer (26) is mounted to an automobile (20). The combination of the intermediate bright film layer (30) with the pigmented transparent layer (32) provides unique gloss and color qualities to automotive trim parts (18) such that the color of the automobile (20) may be matched by the automotive trim part (18) while providing a glossy sheen comparable to the gloss of chrome, for example. As a result, the visual attractiveness of automobiles (20) is enhanced and durable automotive trim parts (18) with no after-fabrication painting are provided.
Abstract:
A plastic laminate (10,12,14) includes three nominal layers (16,18,20), each formed of a selected thermoplastic polymer. A top layer (16) is formed from one or more sheets (17) of a first acrylic material. A second, intermediate layer (18) is formed of one or more PVC sheets (19), at least one of which has a face presenting an image that is at least partially viewable through the top layer. The third, bottom layer (20) is formed of one or more sheets (21a,21b) of either a second acrylic material (which may be the same as the first acrylic material) or an ABS material. Preferably, the bottom layer has a thickness at least as great as the thickness of the top layer. Relatively thicker top and bottom layers are preferably formed of multiple plies of like-thickness sheets which are bonded to one another when the top, intermediate, and bottom layers are hot pressed.
Abstract:
Die Erfindung betrifft eine sortenreine Kunststoffplatte (10) aus einem thermoplastischen Kunststoff, welche sich aus einer Mehrzahl von in einer Ebene nebeneinander angeordneten und gegenseitig gefügten Körpersegmenten (11) aus geschlossenzelligem Schaumstoff zusammensetzt. Die Körpersegmente (11) sind hierzu an ihren anstossenden Seitenflächen unter Ausbildung flächiger Schweissnähte (12, 13) gegenseitig thermoplastisch verschweisst, wobei die flächigen Schweissnähte (12, 13) eine porenarme Kunststoffzwischenschicht in Form einer in Draufsicht netzartigen, die Kunststoffplatte (11) versteifende Stegstruktur ausbilden. Die erfindungsgemässe Kunststoffplatte (11) findet bevorzugt Einsatz als Kernschicht in Sandwich-Verbunden (1).
Abstract:
The present invention is related to a heat sealable coextruded multilayer packaging film peelable on a variety of substrates including polyethylene, polypropylene, polyester, polyvinyl chloride, polyamide, polyacrylonitrile and paper, comprising at least one peelable layer from a pre-compounded precursor formulation containing: - 50 to 80% by weight of an ethylene homo and/or copolymer, - 15 to 25% by weight of a styrene homo or/and copolymer, - 5 to 20% by weight of a thermoplastic elastomeric styrene-butadiene-styrene block copolymer, characterised in that the peel force in said peelable seal film produced by said pre-compounded precursor is modified by the presence in said precursor in the final extrusion step of 5 to 25, and preferably 10 to 20% by weight of homogeneously branched LLDPE and/or polybutene-1.
Abstract:
A multilayered structure comprising, in sequence, an ABS layer, a foamed polyurethane layer and a constraining layer the layers adhering one to the other is disclosed. This composite structure that entails a constrained ABS layer that contains specific additives, and a foamed polyurethane layer that was foamed by 1,1,1,3,3-pentafluoropropane, is characterized by its exceptional resistance to thermal cycling and is therefore suitable for refrigeration purposes.
Abstract:
A thermoplastic resin structure characterized in that it comprises a resin composition consisting substantially of 5 to 80 vol.% polyolefin resin (a) and 95 to 20 vol.% polyphenylene sulfide resin (b) and, when examined with an electron microscope, shows separated resin phases in which the polyphenylene sulfide resin (b) constitutes a matrix phase (continuous phase) and the polyolefin resin (a) constitutes a dispersed phase. This thermoplastic resin structure gives plastic containers, tubular objects, and accessories of these which each is excellent in barrier properties, strength, durability, and moldability.
