Fluoro-Wear 307™

• 4 Times Longer Life Than Standard Roll Covers

• Improved Product Quality

• Eliminates Sticking and Picking

• Increases Production

• Restores Roll Surface to Better Than New

• Mill Site Intallations

• Infinite Shelf Life

Roll covers made with Teflon® have been used by the paper industry for 35 years, but Fluoro-Wear is the first roll cover product of reinforced Teflon®.

When the product was introduced 10 years ago the original wear testing indicated four times greater abrasion resistance than unreinforced FEP made from Teflon®.  Recent thickness measurements taken on a roll cover in service indicate a Fluoro-Wear  roll cover is lasting more than 10 times as long as the unreinforced roll cover.

The reinforced Teflon® has greater strength at higher temperatures. Fluoron's suggested service limit is 400°F (204ºC).  However, one bowed roll cover operating at the end of an infrared oven may see temperature excursions to 500° - 550°F (260ºC - 287ºC) for short periods and has not damaged the roll cover.

Applications:

Because of the excellent wear resistance Fluoro-Wear roll covers are excellent on felt carrying rolls having build-up problems.  Other roll cover applications are high wear bowed rolls, lead in/lead out rolls.
