  • Articles made of PMMA molding compound
    Patent number: 7456239
    Abstract: The invention relates to a moulding composition and to the mouldings which can be produced therefrom. Due to their good resistance in the hot water cycle test and in the hot-water/isopropanol test, the plastics mouldings have particularly good suitability for the production of sanitary components.
    Type: Grant

  • Method for the thermal adhesion of parts made of acrylic plastic and parts made of engineering plastics
    Patent number: 6599387
    Abstract: The invention concerns a method for the production of a flat composite (5) from plastic parts by means of a thermal adhesion of two plastic parts (1,1′), heated on one side of their surfaces (1a,1a′), consisting of plastics A and B, wherein the surfaces (1a,1a′) are heated on the adhesion side to surface temperatures of 10 to 100° K.

  • Method for thermal adhesion of acrylic plastic parts
    Patent number: 5837091
    Abstract: The invention relates to a method for the production of flat laminates (5) from polymethacrylate plastic, by thermal adhesion of at least two parts (1) of polymethacrylate plastic heated at their surface, with the characterizing features that the parts (1) of polymethacrylate plastic, which have been preheated to surface temperatures of 130.degree. to 200.degree. C. on the adhesion side (1a), and which maintain their original shape during the preheating phase, are pressed together between a pair of rollers (2, 3), of which at least one roller (2), by means of which the pressure force (4) is exerted, is mounted in movable manner, at a feed velocity being between 5 and 200 mm/s and a pressure force acting on the roller (3) between 10 and 500 N.
