Resins for portable devices
GE Advanced Materials has introduced two new grades of Lexan EXL polycarbonate/siloxane resin. Lexan EXL 9112 resin and Lexan EXL 1434 resin provide various levels of flame retardancy. They are a suitable for use in portable electronics, converged devices, telecommunications and handheld computer applications.
The resins have retained the properties of polycarbonate, while extending low-temperature impact strength and cold-temperature ductility. The siloxane softblock in the polycarbonate backbone also imparts improved UV stability. The polymer can now provide prolonged resistance to weathering and temperature fluctuations from -40° to 100°C without loss of dimensional stability or ductility.
