Static buildup on industrial rolls: and the Fluoro-Stat answer.
Conductive PTFE roll covers for static-sensitive lines.
Dry-end paper-mill rolls, flexible-packaging webs, and converting lines build static charge under tension. Standard PTFE and FEP are insulators, so a non-stick cover alone does not solve the problem. Fluoro-Stat is Fluoron’s carbon-reinforced PTFE roll cover: it bleeds off static charge while keeping the PTFE non-stick surface and chemical resistance.

How static buildup shows up on industrial rolls
As a web moves over an idler, nip, or spreader roll, friction between the web and the roll separates electric charge. The charge sits on the web and on the roll surface. On a roll with an insulating cover: standard PTFE, FEP, or rubber : that charge has nowhere to go, so it builds.
Static buildup shows up as web carryover and stuck layers, misregistered prints, defects on packaging film, and arcing that can damage electronics near the line. On dry-end paper and converting positions it is one of the most consistent sources of avoidable downtime.
Replacing a rubber roll with a standard PTFE or FEP cover solves the buildup and release problem, but does not solve the static problem: both polymers are good electrical insulators by themselves. The static problem needs a conductive cover.
A carbon-reinforced PTFE cover is electrically conductive. Static charge picked up by the cover bleeds through the cover, through the bonded interface, into the grounded roll body and out of the process. That is what Fluoro-Stat is built to do.

When to spec Fluoro-Stat instead of standard PTFE
Wet lines tend to bleed static through moisture; dry-end and dry-position rolls have nowhere for charge to go. That is exactly the case Fluoro-Stat solves.
Web carryover, stuck layers, mis-registered prints, and arcs near electronics are static symptoms. If a non-stick cover alone has not fixed the issue, a conductive cover is the change.
Fluoro-Stat keeps the PTFE non-stick surface and chemical resistance buyers expect from Fluoro-Wear. You are not trading release performance for static control.
Same heat-shrink install as the rest of the Fluoron sleeve platform.
Fluoro-Stat installs with the same controlled-heat process as Fluoro-Wear, Fluoro-Flex, and Fluoro-Clear. The cover is sized to the roll OD and recovers into a tight mechanical fit; bonding to a grounded roll body completes the static-dissipative path. Onsite installation is supported worldwide for large mill rolls.
