WHITE ACRYLIC TRASLUCEN 2447 PLEXIGLASS 1/8" thick (12 X 24) Weatherability: Polycast acrylic sheet has exceptional weathering characteristics. Clear sheet will not yellow even after long years of exposure to sunlight, and colors won't fade. Polycast acrylic sheet is an excellent insulator. Its surface resistivity is higher than that of most plastics. Continuous outdoor exposure has little effect on its electrical properties. Like most plastics, Polycast acrylic sheet responds to temperature changes by expanding or contracting at a far greater rate than glass When using Polycast acrylic sheet for outdoor glazing, cut the sheet approximately 1/16" per running foot shorter than the frame size. Translucent white Polycast acrylic sheet diffuses light smoothly and evenly Polycast acrylic sheet is much more flexible than glass or many other building materials. When using large sheets for windows, it is important that rabbets or channels be deep enough to provide support against high winds.
