Fluor-XR

Fluor-XR Extreme Release non stick coating is a highly differentiated product that combines the wear resistance of a tungsten carbide surface with the superior release properties of Fluoron’s proprietary extreme release coating technology.

Unlike traditional roll covers or coatings, Fluor-XR technology embeds the release coating within a protective matrix of tungsten carbide which enables superior release even under the most aggressive services. Fluor-XR is FDA approved and provides excellent benefits in most food manufacturing applications.

Fluor-XR Installation Process

The Fluor-XR installation consists of a three step process. First, the roll surface is prepared using vacuum grit blasting equipment to provide a clean working surface. An 80 micron layer of tungsten carbide is then applied using High Velocity Oxygen Fuel (HVOF) flame spray equipment. Finally, Fluoron’s proprietary Extreme Release coating is applied to produce a finished high release surface.

Fluor-XR Has 40X Better Release Than PTFE


To test wear resistance and simulate release under aggressive operation, Fluoron engineers prepared sample coupons of our proprietary tungsten carbide matrix and Fluor-XR top coat. The samples are placed in a rotating wear testing device where a steel blade is scraped across the sample surface under 300 lbs/in2 of force for 4000 cycles.

To simulate stickies adhesion, TESA 7475 standard tape is applied to the worn Fluor-XR sample surface as well as sample coupons of traditional PTFE. All sample coupons are conditioned at 160°F for 24 hours.

The TESA 7475 tape is removed from each sample surface using a ChemInstruments AR-1000 Adhesion Release tester which measures the force required in grams to remove the tape from the surface.

Testing results show that Fluor-XR provides over 40 times better release than the best PTFE materials in adhesive
applications, even after extensive wear testing!
