The answer is simple: it combines <strong>excellent electrical insulation, high mechanical strength, great heat &amp; moisture resistance, flame retardancy, and easy processability<\/strong>&nbsp;\u2014 all in one material. Unlike glass, it won\u2019t shatter; unlike many cheap plastics, it won\u2019t lose insulation properties under high temperature or humidity.<\/p>\n\n\n\n<p class=\"has-link-color wp-elements-378511d32af3f33584f5745ad93b71aa\">In this guide, we will explain every key insulation property of polycarbonate\u00a0sheet, compare it with other common materials, show real electrical application cases, and share <strong>how to choose the right polycarbonate\u00a0sheet\u00a0for your electrical project<\/strong>.
