Cyro Industries, Rockaway, N.J., developed Acrylite GP P95, a black/white acrylic sheet (Cyro color 1124-1) made from a special pigment formulation designed for 10-19% light transmittance when backlit An LCD screen that has its own light source from the back of the screen, making the background brighter and characters appear sharper. but appearing dark and opaque without backlighting. The sheet is an addition to Cyro's cell-cast Acrylite GP line, so it offers the same performance and fabrication fabrication (fab´rikā´sh n the construction or making of a restoration. characteristics. The amount of light transmission can be adjusted by varying the percentage of pigment in the sheet so that transmission is the same for all thicknesses. Neon, fluorescent, and incandescent light sources can be used for backlighting. However, the service temperature of the sheet cannot exceed 180 F and the light source should never touch the sheet. Available in standard thicknesses of 1/8, 3/16, and 1/4 in., the new sheet has a matte side (called the P95 side), and a glossy side. The matte side is said to diffuse the backlighting to reduce glare. Acrylite GP P95 can be thermoformed but only under carefully controlled conditions with very little draw. That's because the sheet's "sandblast sandblast, stream of sand or other abrasive particles driven by a jet of compressed air or water or by centrifugal force against a surface to clean or abrade it.
