Signage options for thermoformers. (Thermoforming).New acrylic acrylic, artificial fiber made from a special group of vinyl compounds, primarily acrylonitrile. Acrylic fibers are thermoplastic (i.e., soften when heated, reharden upon cooling), have low moisture regain, are low in density, and can be made into bulky fabrics. and polycarbonate A category of plastic materials used to make a myriad of products, including CDs and CD-ROMs. sheets for channel lighting and outdoor signs have been launched by Atoglas, a unit of AtoFina Chemicals in Philadelphia. Implex Plus high-impact acrylic, already offered in white and black, is now available in other popular signage colors. A second new acrylic sheet is light-diffusing Plexiglas for channel lighting with LEDs. The intensity of LEDs imposes stricter requirements than do conventional fluorescent fluorescent having the quality of fluorescence. fluorescent antibody see fluorescence microscopy. fluorescent antibody test see fluorescence microscopy. lights. A third new sheet is Tuffak XL 25710 for outdoor signs. This multi-layer polycarbonate sheet offers more intense whiteness than other sheet by including a weather-resistant cap-stock. Its improved light diffusion diffusion, in chemistry, the spontaneous migration of substances from regions where their concentration is high to regions where their concentration is low. Diffusion is important in many life processes. translates into more uniform glow and reduced power needs in outdoor signs. Tel: (800) 647-5569, www.atoglas.com |
