Description

Polycarbonate, also referred to as PC, is a tough, impact-resistant, virtually unbreakable material used in wide variety of applications. It is an amorphous thermoplastic material, with a continuous use temperature range of up to 265° F (129° C). LEXAN™ is one of the most commonly recognized polycarbonate brands.  Polymershapes is the leading North American distributor of LEXAN.

Polycarbonate is commonly used in see-through applications, such as machine guards, windows (glazing), windshields for golf carts and other recreational vehicles, and Point of Purchase displays. Polycarbonate is 20 times stronger than acrylic and is retains is physical properties over a greater range of temperatures. Polycarbonate is more than 200 times stronger than glass. LEXAN Polycarbonate sheet comes in a variety of textures and surface patterns for the purpose of light diffusion, privacy and printing. It can be cut, routed, drilled, and milled. Graphics can be direct printed or laminated.

Polycarbonate is considered a high performance material due to its excellent balance of engineering properties, including excellent impact strength, and electrical properties. It offers great dimensional stability and a large operating temperature range. Machine grade PC is available in sheet, tube and rod, and is extremely versatile, allowing designers and engineers to specify it in a wide variety of industrial applications. LEXAN is also available in filament form for use in certain 3D printers.
