Abstract
A method for the production of laminates comprises extruding a support of acrylic nitrile-butadiene-styrene (ABS) and a coating of polymethyl methacrylate (PMMA, acrylic glass) through a sheet die. The acrylic glass forming the coating has a melt flow index of at most 2.0 (MFI 230.degree. C./3.8 according to DIN 53735) and the ABS forming the support are conducted directly to the die through different channels.
Claims2
A method for the production of bath tub inserts for a deep-drawing process comprising coextruding a support of acrylic nitrile-butadiene-styrene and a coating of polymethyl methacrylate which is on the support, through a sheet die, while forming a coating of acrylic glass over the support which has a melt flow index of at most 2.0 (MFI 230.degree. C./318) according to DIN 53735 by conducting the coating and the support directly to the die through different channels so as to form panels, producing bathtub inserts by a deep-drawing.
