Acrylic: This plastic sheet is completely transparent, flexible, and exhibits great resistance to breakage. Acrylic is excellent material to use in place of glass for windows, skylights, doors, partitions, etc. It is lightweight, half the weight of glass, and it is virtually unaffected by nature. Acrylics transparency, gloss and dimensional shape are virtually unaffected by years of exposure to the elements, salt spray or corrosive atmospheres. These materials withstand exposure to light from fluorescent lamps without darkening or deteriorating. They ultimately discolor, however, when exposed to high-intensity UV ligh below 265 nm. It can take temperatures from -40 deg F to 180 deg F (intermittent to 200 deg F). Fabrication is easy, as it can be sawed with fine tooth blades, drilled with plastic drills, sanded and polished. Also, it can be cemented with Acrylic cement. It meets FDA standards, is UV stabilized, and has a UL 95 Flammability rating. The forming temp is 350 deg F. Applications include inspection windows, sight gauges, windshields, meter faces, protective covers, safety shields, tanks, desk tops, displays, trays, and chair pads.
