For outdoor clarity we specify a UV-coated grade or add a hard-coat after moulding. If the part is purely structural, an opaque PC\/ABS blend is cheaper and tougher at the edges.<\/p>\n<h3>Can PC be overmoulded with a soft-touch material?<\/h3>\n<p>Yes, with a TPE or TPU grade formulated for PC adhesion. The PC insert needs to be dry and the bond improves markedly if the insert is preheated to around 80 \u00b0C.<\/p>\n<\/p><\/div>\n<h2>Related materials<\/h2>\n<ul class=\"related\">\n<li><a href=\"\/de\/abs-injection-molding\/\">ABS Injection Molding<\/a><\/li>\n<li><a href=\"\/de\/pp-injection-molding\/\">PP Injection Molding<\/a><\/li>\n<li><a href=\"\/de\/pe-injection-molding\/\">PE Injection Molding<\/a><\/li>\n<li><a href=\"\/de\/nylon-pa-injection-molding\/\">Nylon Injection Molding<\/a><\/li>\n<li><a href=\"\/de\/pom-acetal-injection-molding\/\">POM Injection Molding<\/a><\/li>\n<li><a href=\"\/de\/acrylic-pmma-injection-molding\/\">PMMA Acrylic Injection Molding<\/a><\/li>\n<\/ul>\n<p><a href=\"\/de\/injection-molding\/\">\u2190 All Injection Molding Solutions<\/a><\/p>\n<div class=\"cta\">\n<h2>Send us your PC drawing<\/h2>\n<p>Upload a 3D model or a 2D drawing and we will come back with a DFM review, a tooling cost and a piece price \u2014 usually within two working days.<\/p>\n<p>    <a class=\"btn\" href=\"\/de\/kontakt\/\">Request a quote<\/a>\n  <\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Polycarbonate is what you specify when a part has to be transparent and survive being hit.
