Acrylic, also known as PMMA, is a thermoplastic that can be formed into a number of shapes, making it suitable for use in a broad range of applications. Our acrylic sheet options are ideal for a vast array of projects, including signage, displays, skylights and hundreds more. Acrylic has a variety of high-performance properties, among the most important being its optical clarity, low Ultra Violet sensitivity, and overall weather resistance. Acrylic provides a clear, glass-like brilliance and translucence, but is much lighter and much more durable than glass. Acrylic is sold under brands like Optix, Plexiglas, Lucite and Acrylite.
