Abstract

Abstract Translated from German Verfahren zur Herstellung von Verbundplatten, wobei eine Unterlage aus Acrylnitril-Butadien-Styrol (ABS) und ein Überzug aus Polymethylmethacrylat (PMMA, Acrylglas) durch eine Breitschlitzdüse koextrudiert werden. Das den Überzug bildende Acrylglas mit einem Schmelzindex von höchstens 2,0 (MFI 230°C|3,8 nach DIN 53735) und das die Unterlage bildende ABS werden durch verschiedene Kanäle unmittelbar an die Düse herangeführt. Process for the production of composite panels, wherein a base made of acrylonitrile-butadiene-styrene (ABS) and a coating made of polymethyl methacrylate (PMMA, acrylic glass) are coextruded through a slot die. The acrylic glass forming the coating with a melt index of at most 2.0 (MFI 230 ° C | 3.8 according to DIN 53735) and the ABS forming the base are brought directly to the nozzle through various channels.
