Fluoro-Stat™ Might Be Better For You

In Some Roll Positions Fluoro-Stat™ Might Be the Only Option!

FEP is the most common heat shrinkable sleeve for various rolls on a paper machine, but that doesn’t mean it’s the best heat shrinkable sleeve for your roll!

FEP provides good release but can’t handle some of the conditions common in a paper machine. Fluoro-Stat™ 102 is a heat shrinkable sleeve that is able to withstand higher temperatures and is not subject to static build-up like FEP.

  • Fluoro-Stat™ can handle operating temps of 400ºF
  • Fluoro-Stat™ has 4-10 X the life of FEP
  • On spreader rolls, unlike Fluoro-Stat™, FEP is susceptible to flex-fatigue cracking.
  • In positions where the sheet has a low moisture content, static electricity is likely with FEP and can not only cause sheet imperfections but can also cause safety issues and burn holes in the cover due to electrical discharges or arcing. Fluoro-Stat is conductive, when grounded there is no static build-up.
