Is it possible to manufacture polypropylene sheets using a biaxial process?

22 July 2024 1 2K Report

I know that films and other low-thickness laminated products are produced using biaxial orientation, but is there something similar for sheets with a thickness of around 6 mm? Or are they exclusively manufactured with monoaxial orientation?

Abdelhak Maghchiche

Yes, polypropylene sheets can be manufactured using a biaxial process, which involves extruding, quenching, and biaxially stretching the sheet. This method enhances the mechanical and optical properties of the polypropylene, making it suitable for various applications.
