Why Choose 4mm Clear Twinwall Polycarbonate

The term “Twinwall Polycarbonate” refers to a polymer made up of many identical units of bisphenol A linked by carbonate connections in its backbone. Chemically, a twinwall carbonate group is a di-ester of carbonic acid, forming a long polymeric chain.

Production Process

Twinwall polycarbonate is shaped by melting the polymer and forcing it under pressure into a mold or die. The two primary methods for creating products from twinwall polycarbonate are:

Extrusion: This process continuously presses the molten polymer through an orifice, giving it its final shape. It allows for the creation of infinitely long pipes, profiles, or sheets.
