A transparent, solid sheet made of [[acrylic%20resin|acrylic resins]]. Originally introduced as 'organic glass' in 1931, the thermoplastic acrylic sheets are prepared by cast polymerization or extrusion. Some common brand names are [[Plexiglas%C2%AE|Plexiglas®]], [[Perspex|Perspex]], and [[Lucite%C2%AE|Lucite®]]. Acrylic sheets are lightweight, tough, and colorless with excellent clarity and outdoor weather resistance. Compared to glass, acrylic is lighter and shatter-resistant, but more susceptible to scratching and transmission of UV.  Acrylic has the unique ability to carry light around corners. Acrylic sheets are used for safety glass, aircraft canopies, windows, skylights, signs, instrument dials, tail light lenses, lighting fixtures, optical lenses, storage and display cases, bulletproof glass.

Description

A transparent sheet or film made of acrylic resins. Originally introduced as 'organic glass' in 1931, the thermoplastic acrylic sheets are prepared by cast polymerization or extrusion. Some common brand names are Plexiglas®, Perspex®, and Lucite®. Acrylic sheets are lightweight, tough, and colorless with excellent clarity and outdoor weather resistance. Compared to glass, acrylic is lighter and shatter-resistant, but more susceptible to scratching and transmission of UV. Acrylic has the unique ability to carry light around corners. Acrylic sheets are used for safety glass, aircraft canopies, windows, skylights, signs, instrument dials, tail light lenses, lighting fixtures, optical lenses, storage and display cases, bulletproof glass. Other types of clear plastic glazing include Polycarbonate sheets (e.g. Lexan®).
