摘要:
A process for the preparation of a plastic composite is disclosed. The composite contains a first fluoropolymer layer, a second, middle layer of polycarbonate and a third layer of ethylene-vinyl acetate copolymer. The process entails preparing a plastics composite of fluoropolymer and polycarbonate layers and applying the layer of ethylene-vinyl acetate copolymer to the polycarbonate layer.
摘要:
A multi-layer article is disclosed. The article contains a base layer that contains at least one thermoplastic resin and a second layer containing a thermoplastic (co)polyformal superimposed over the base layer. The (co)polyformal conforms to formulae (1a) or (1b), in which O-D-O and O-E-O independently denote a diphenolate group, -D- and -E- independently denote an aromatic group having 6 to 40 carbon atoms, k is a whole number from 1 to 1500, o stands for numbers from 1 to 1500, and m is z/o and n is (o-z)/o wherein z is 0 to o.
摘要:
The present invention concerns a compound made of transparent thermoplastic resin, particularly polycarbonate, and a combination of inorganic particles on the basis of silicone dioxide and polymer particles on an acrylate basis with core-shell morphology, as well as moulds made from this compound.
摘要:
A transparent sheet having improved optical properties is disclosed. The sheet that features a deviation angle αε (min) according to DIN 52305-A-AS of ≦2.0 and a refracting power Dε (min) according to DIN 52305-A-AZ of ≦0.05, is prepared by extruding a molding composition comprising linear (co)polycarbonate having weight average molecular weight of 25,000 to 31,000.
摘要:
The present invention relates to a solid sheet prepared from a composition that includes: (a) a transparent polycarbonate; and (b) transparent polymeric particles having an optical density which differs from the transparent polycarbonate matrix material. The present invention also relates to use of such a solid sheet as a diffuser sheet in flat screens.
摘要:
A light-emitting, transparent, flexible film system based on polymers is produced by including a thermoplastic polyurethane film having an electroluminescent pigment incorporated therein in the flexible film system. These systems are useful as a luminescent system.
摘要:
The invention relates to a device for the continuous production of plastics/metal composite panels, in particular those having hollow chambered sections, from thermoplastic polymers (3) and continuous metal sheets (6, 7), consisting of at least one plastics melting control system (1), calibrators (4, 5), feeds for the metal sheets (10, 11) and a draw-off unit (9), with the feeds for the metal sheets (10, 11) being arranged respectively above and below the melting control system (1) and the calibrators (4, 5) being immediately adjacent to the feeds (10, 11) and the melting control system (1).
摘要:
A reinforced polyamide molding composition is disclosed. Characterized in that its viscosity at a shear velocity of 10 s−1 is greater than 1000 Pas and a shear velocity of 1000 s−1 is less than 300 Pas, at processing temperatures of 40 to 80° C. above its melting point, the composition is particularly suitable for thermoforming applications.
摘要:
A process for the production of coated planar moldings of thermoplastics is disclosed. The process entails extrusion of a molded body, cooling of the molding, applying the aqueous-based coating agent and drying. The coating agent, having a pH value of less than 6, contains a salt of sulfondicarboxylic diester, a water-insoluble oxide of metal or semi-metal and an acid/water mixture. It is applied to at least one surface of the molding immediately after the production of the molding and with the aid of an application roll.
