The term “Sevenwall Polycarbonate” refers to a specialized polymer made up of identical units of bisphenol A, which are linked by carbonate connections in its backbone chain. Chemically, this structure forms a di-ester of carbonic acid, resulting in a robust polymeric chain.

Sevenwall polycarbonate is shaped through a process that involves melting the polymer and then forcing it under pressure into a mold or die. One of the primary methods used in producing sevenwall polycarbonate is extrusion. During this process, the molten polymer is continuously pressed through an orifice, which shapes the material into its final form. This technique allows for the creation of infinitely long pipes, profiles, or sheets, providing exceptional versatility for various applications.
