Prepared by cast polymerization or extrusion; 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. Originally introduced as 'organic glass' in 1931.  ]]></note></mads>
