| New Lexan sheet opens up new opportunities for illuminated signage  GE Plastics has introduced a new grade of Lexan polycarbonate (PC) sheet that is specifically designed to boost the visibility and attractiveness of illuminated signage. Lexan SG305-OB sheet, unlike conventional sheet products, offers both uniform light diffusion to eliminate light emitting diode (LED) "pinholes" and a view of light sources, and superior light transmission for exceptional optical brightness at lower energy costs. In fact, the 2mm and 5mm thicknesses of Lexan SG305-OB sheet boost light transmission to more than 50 percent, vs. competitive materials like polymethyl methacrylate (PMMA) that allow only about 25 percent. The new white sheet grade, which has a matte finish on its outward-facing surface to reduce reflections, also provides excellent UV protection as well as the renowned impact resistance of tough, virtually unbreakable Lexan resin.The outstanding aesthetics, performance, and formability of GE's new Lexan SG305-OB sheet are spurring innovative new lighting solutions, such as the ADDscreen illuminated roll-down security shutters offered by Euroll and ADDscreen, both of The Netherlands. These shutters, which protect stores, ticket windows, and other spaces after hours, feature computer-generated advertising that is beamed onto the reverse side. The SeaCloud Hotel in Busan city, South Korea is using Lexan SG305-OB sheet for its main exterior sign and others are following suite. The hotel sign utilizes a color-changing system, which occurs when Lexan SG305-OB sheet is installed with a gray-colored film. As a result, the material shows as gray during the day and white at night when displayed with LED lamps. This gray color film has many small holes which allow lamp light to pass through when it is dark. write your comments about the article :: © 2007 Construction News :: home page |
