Multi-Wall Sheet Extrusion
BMS designs and produces different grades of transparent Makrolon® polycarbonate resins for the extrusion of multi-wall sheets.
Applications for multi-wall sheets of Makrolon® resins include industrial and residential products:- Sidewalls and roofs of greenhouses, industrial buildings, building and construction.
- Window panes for sun rooms, verandas, and carports in the private household sector.
- The do-it-yourself market.

Multi-wall sheets have the following features:
- Varying widths. Maximum width is 7 feet (2.1m).
- Thicknesses: Can range from approximately 0.157 to 1.77 inches (4 to 45mm).
- Length: Dependent on the equipment.
- Option to coextrude an ultra-violet (UV) protection layer on the top surface of the sheet.
- Transparent, translucent, and opaque colors possible.
- High degree of thermal insulation.
- Light-weight material.
- Increased weathering resistance when coextruded with a UV concentrate from BMS.
- Continuous production and high output possible.
This processing guide for multi-wall sheet extrusion reviews the products available from BMS, the type of equipment used to extrude the material, and the processing properties of the grades. Design engineers, extrusion process engineers, and extrusion technicians will find helpful information for using Bayer products for the extrusion of multi-wall sheets in the following sections:
