Cutting Flat Polycarbonate Sheets

MARLON FS/FSX is easy to saw and cut on standard workshop equipment. It can be machined on conventional milling machines with standard high speed tools. Notches adversely affect the mechanical properties of polycarbonate sheets and should be avoided.

The following points should be observed when drilling MARLON FS:

  • - Do not use cutting oils
  • - Use a new drill that has not been used for drilling other materials
  • - The sheet may break as a result of notching
  • - Do not countersink fixings
  • - Fixing threads should only be used if there is no alternative
  • - The hole should be at least 1.5 x hole diameter from the edge of the sheet.
  • - The hole diameter should be 6mm larger than the fixing shank diameter for sheets up to 2m and anadditional 3mm per metre length thereafter.
