What is Multiwall Polycarbonate?

product_imagesIt is a polycarbonate sheet consisting of two or more layers depending on the thickness of the sheet. Multiwall polycarbonate sheets are produced through an extrusion process. A screw driven extruder heats and pushes the polycarbonate material through dyes. The result is a lightweight sheet with a fluted internal structure, high impact strength, and superior thermal insulation. Polycarbonate multiwall sheets are fabricated in a variety of profiles such as two-wall, three-wall, five-wall and five-wall x-structure.

Also, called “cellular polycarbonate” or “polycarbonate structural sheet”.
