MANUFACTURE OF COMPOSITE BOARD

摘要

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 DEG C./3.8 according to DIN 53735) and the ABS forming the support are conducted directly to the die through different channels.
