| G-Lex is a polycarbonate compound that has been made from a specified and approved feedstock for the last fifteen years. It is noted for its high impact resistance over a wide range of temperatures. It has excellent heat resistance and all grades pass the 850oC glow wire test at 1.0mm. The high flow grade is particularly suited to thin wall, long flow length application. G-Lex complies with all recycling directives and can be recycled in the normal way. After its first application the resin can be reground and reused either in a similar manner or cascaded down for reuse in less demanding applications. Typical applications include electrical goods, lighting, telecommunications, appliances and security devices and other applications where strength and impact are important. This material is available in Black and natural and most semi translucent, translucent and opaque colours.&& |
