01 / Background
About Fluoron and our products.
What does Fluoron manufacture?
Fluoron designs and fabricates heat shrink fluoropolymer roll covers and sleeves for industrial rollers. Our product line includes four grades: Fluoro-Clear (FEP), Fluoro-Flex (PFA), Fluoro-Wear (PTFE), and conductive PTFE anti-static (Fluoro-Stat). We serve pulp and paper, printing, laminating, converting, packaging, food processing, textile, and specialty web-processing industries. Fluoron is headquartered in Elkton, Maryland and has been in operation since 1993.
Is Fluoron the same as Teflon®?
Teflon® is a registered trademark of The Chemours Company. Fluoron is an independent manufacturer of fluoropolymer roll covers, not affiliated with Chemours. Our products are made from the same classes of fluoropolymer materials (FEP, PFA, PTFE) that underlie Teflon® branded coatings, but we manufacture and sell them under our own brand names: Fluoro-Clear, Fluoro-Flex, Fluoro-Wear, and Fluoro-Stat.
What industries does Fluoron serve?
Pulp and paper (dryer cans, press rolls, felt rolls), printing (offset, flexo, gravure), laminating and film converting, packaging, food and pharmaceutical processing, textile and nonwovens, extrusion, electronics web handling, and aerospace and industrial specialty applications.
02 / Material Selection
Pick the right fluoropolymer.
FEP, PFA, and PTFE all release adhesives and residue, but they differ in temperature tolerance, wear life, and cost. Match the material to the failure mode.
FEP
Fluoro-Clear
Max 350°F · seamless to 18″ OD · most economical
PFA
Fluoro-Flex
Max 400°F · ~4× FEP life · rubber nip rolls
PTFE
Fluoro-Wear
Max 500°F · ~10× FEP life · highest wear
Conductive PTFE
Fluoro-Stat
Static-dissipative · 10⁶–10⁹ Ω/sq · dry rolls
What is the difference between FEP, PFA, and PTFE roll covers?
All three are fully fluorinated polymers with non-stick, chemical-resistant surfaces. Key differences:
- FEP (Fluoro-Clear): Most economical, seamless up to 18″ OD, max 350°F, low-wear positions.
- PFA (Fluoro-Flex): ~4× FEP service life in nip rolls, max 400°F, elevated-temperature positions.
- PTFE (Fluoro-Wear / Fluoro-Stat): ~10× FEP wear life, max 500°F, always seamed, high-wear environments.
What is Fluoro-Stat and when do I need it?
Fluoro-Stat is conductive anti-static PTFE with a carbon black filler that makes the sleeve static-dissipative (surface resistance 10⁶–10⁹ Ω/sq). Standard FEP, PFA, and unfilled PTFE sleeves are electrical insulators. In dry-area roller positions with fast-running webs, they accumulate static that can arc, damage the sleeve, create web defects, or pose fire and explosion risk. Fluoro-Stat bleeds off charge continuously through the grounded roller core. See the Fluoro-Stat product page →
My rollers run in both wet and dry sections. Do I need different sleeves?
Possibly, yes. FEP (Fluoro-Clear) or PFA (Fluoro-Flex) are appropriate for wet-section rolls. For dry-section rolls where static is a risk, particularly with fast-running webs of film or paper, conductive PTFE is the correct choice. Fluoron can help you map roll positions to the appropriate sleeve grade.
Are Fluoron sleeves FDA-compliant for food contact?
Yes. FEP (Fluoro-Clear) and PFA (Fluoro-Flex) are manufactured from FDA-compliant virgin resins. PTFE is also FDA-compliant in its virgin form. For Fluoro-Stat, carbon additives at low loading levels are compliant with FDA 21 CFR 178.3297. Confirm with Fluoron engineering for specific food-contact applications.
03 / Sizing & Fabrication
Sized to your roll, not a catalog.
What roller sizes can Fluoron cover?
FEP (Fluoro-Clear) and PFA (Fluoro-Flex) are available as seamless sleeves up to 18″ OD. Larger diameters use a smooth-finish fluoropolymer weld seam with no practical upper diameter limit. PTFE grades (Fluoro-Wear and Fluoro-Stat) start at 4″ minimum OD. All PTFE sleeves have a weld seam regardless of diameter.
Can Fluoron make a non-standard diameter or length?
Yes. Every sleeve is fabricated to the exact OD and face length of your roller. There are no standard shelf sizes that constrain your order. Provide the roll OD, face length, and material grade, and we fabricate to specification.
What wall thicknesses are available?
Standard thicknesses are 0.020″ (0.5 mm) and 0.060″ (1.5 mm) for FEP. PFA and PTFE grades are standard at 0.060″ (1.5 mm). Other thicknesses may be available on request. Contact Fluoron engineering for non-standard wall requirements.
04 / Installation
Three install paths: in-shop, onsite, or train your team.
Can we install the sleeves ourselves?
Yes, with proper training. Non-bonded FEP sleeve installation on smaller rolls is well within the capability of a trained maintenance team with the right heat gun equipment. Bonded installations and all PTFE sleeve installations are more technically demanding. Fluoron recommends trained-technician installation or supervised first installation. See the installation guide →
Does Fluoron offer onsite installation?
Yes. Fluoron field technicians travel internationally to install sleeves when shipping the roller is impractical. We bring the spec sleeves, the controlled heat equipment, and install on your line with QA verification before signoff.
05 / Service Life & Maintenance
How long does a Fluoron sleeve last?
What is the typical service life?
Service life depends on application, but typical ranges are: FEP (Fluoro-Clear) 1–3 years in moderate-duty positions; PFA (Fluoro-Flex) 3–5 years in nip and elevated-temperature positions; PTFE (Fluoro-Wear) 5–10+ years in high-wear positions. Conductive PTFE (Fluoro-Stat) tracks PTFE wear life. Heavily contaminated or extreme-temperature environments shorten life; clean operation extends it.
How should sleeves be cleaned?
Fluoropolymer surfaces release most adhesives and residues with mild solvents or aqueous detergents. Avoid abrasive scrubbers that can scratch the surface. For heavy buildup, Fluoron can recommend application-specific cleaning chemistries or refer customers to Radiant Cleaning (our sister division) for dryer cylinder cleaning service.
Can sleeves be repaired?
Minor punctures or surface damage can sometimes be patched depending on material grade and damage location. Major damage typically warrants replacement. Send photos and the roll OD/face length to engineering for an assessment.
06 / Quoting & Lead Times
Quote-ready in three minutes.
How do I request a quote?
Use the Spec Tool to enter your roll dimensions, service environment, and the issue you are seeing. Engineering responds with a material recommendation, lead time, and quote, typically within one business day. For shorter questions, email [email protected] or call 410-392-0220.
What is the typical lead time?
Standard lead times: FEP and PFA sleeves 2–4 weeks from order. PTFE grades 3–5 weeks. Expedite available for urgent outages, contact engineering. Onsite install scheduling typically adds 1–2 weeks after the sleeve is ready.
What information does Fluoron need to quote?
Minimum: roll OD, face length, service temperature, and what is failing (sticking, wear, static, etc.). Helpful additions: line speed, contact chemistries, photos of the current roll, and your sister-position install history. The Spec Tool walks you through it.
