The short answer
Fluoropolymers are the pick when a part has to survive chemicals, heat or electrical stress that would ruin other plastics. Choose the family by process first (PTFE cannot be melt-processed; PFA, FEP, ETFE and PVDF can), then by temperature and the chemical list. The most common mistake is paying for a fully fluorinated resin where PVDF or ETFE would do, or the reverse: specifying PVDF and then finding a strong base or ketone in the stream.

About Fluoropolymers
Fully fluorinated grades offer the best chemical resistance in plastics, with a wide temperature range, low friction and excellent electrical properties; partially fluorinated grades trade some of that for strength and easier processing. Selection is a trade between processability, mechanical strength and temperature ceiling, exactly the call a chemist helps you make.
Common applications
- Chemical processing linings and components
- Wire and cable insulation
- Semiconductor fluid handling
- Seals, bearings and gaskets
- Architectural films
Typical properties
| Impact strength | Good |
|---|---|
| Heat (service) | ~150-260°C continuous |
| Clarity | FEP/PFA films transparent |
| Chemical resistance | Outstanding |
| Relative cost | High-very high |
Property ranges are general guidance and vary by grade and supplier; a polymer chemist confirms the exact spec against the data sheet and certificate of analysis for your application.
Which grade to ask for
Start with how the part will be made, then the service temperature and the chemicals it sees.
| Grade type | Use it for | Watch out for |
|---|---|---|
| PTFE granular and filled compounds | Seals, valve seats, bearings, billets for machined parts, up to about 260°C / 500°F | Not melt-processable; unfilled grades creep under load |
| PTFE fine powder | Paste-extruded tubing, thin wire insulation, thread-seal tape, membranes | Shear-sensitive; needs cool storage and gentle handling |
| PFA | Molded fittings, high-purity tubing and linings, up to about 260°C / 500°F | Highest cost of the melt-processable group; needs corrosion-resistant equipment |
| FEP | Plenum cable, thin-wall tubing, film and heat-shrink, up to about 200°C / 392°F | Lower heat ceiling than PFA; melt fracture at high line speed |
| ETFE | Tough wire insulation, molded pump and valve parts, film, up to about 150°C / 302°F | A few strong oxidizers and hot solvents attack it |
| PVDF | Pipe, valves, sheet and molded parts, up to about 150°C / 302°F; the easiest to process | Strong bases, amines and some ketones and esters attack it |
Typical starting points. Grades vary, so confirm on the data sheet for the exact grade.
Grade lists for the two partly fluorinated resins are on the PVDF resin and ETFE resin pages.
Processing notes
- Process. PTFE is compression molded and sintered, ram extruded or paste extruded; it does not flow as a melt. PFA, FEP, ETFE and PVDF run on injection and extrusion equipment, at melt temperatures from about 200°C / 392°F (PVDF) up to about 400°C / 752°F (PFA and FEP). Each resin's page gives its own range.
- Drying. No drying needed in most grades, because water absorption is very low. Let cold bags reach room temperature before opening so condensation does not form.
- Corrosion. Fluoropolymer melts, and the gases they release when overheated, attack ordinary tool steel. Barrels, screws, nozzles, dies and cavities should be corrosion-resistant (typically high-nickel alloys, or what the producer recommends). Standard steel pits and sheds black specks.
- Fumes. Fumes released at processing temperatures, and especially on overheating or purging, can cause polymer fume fever, a flu-like illness. Exhaust the nozzle, die and sintering oven, keep residence time short, and keep tobacco out of handling areas.
- Shrinkage. High for a thermoplastic, commonly several percent, and direction-dependent. Plan on machining or tool trials for tight tolerances.
- Regrind and the common defect. Clean, same-grade regrind is often reused in industrial parts; high-purity programs usually allow none. The most common defect is melt fracture (a rough, frosty surface) from small gates, small dies or high shear.
What to put on the purchase order
- The family and form: PTFE granular, free-flow, presintered, fine powder or micropowder; or PFA, FEP, ETFE or PVDF as pellets, or as powder for coating and rotolining.
- Melt flow rate with its test condition, and the range you accept. PTFE has no usable melt flow, so specify standard specific gravity (SSG), bulk density and particle size instead.
- Fill type and percentage for filled PTFE or ETFE (glass, carbon, graphite, bronze), and whether reprocessed PTFE is acceptable.
- Purity level: standard industrial, or a high-purity grade with extractables data for semiconductor or pharmaceutical fluid handling.
- Documents by grade: ask for the producer's FDA letter for the exact grade and a written PFAS declaration. UL recognition is grade-specific and color-specific; check the grade's listing on UL Product iQ.
- COA values to check: melt flow or SSG against the agreed range, melting point where reported, and contamination or speck counts on high-purity lots.
- Packaging: lined bags, boxes or drums. Fine powder must be kept cool, so ask how the lot was stored.
When to consider something else
- If the part sees acids and bases at moderate temperature and cost matters most, look at polypropylene or PVC.
- If you need strength and stiffness at high temperature along with broad chemical resistance, look at PEEK or PPS.
- If you need low friction and wear resistance at low temperature, look at UHMW-PE or wear and friction fillers.
- If a customer wants PFAS-free materials, start with PFAS-free alternatives. Few are exact drop-ins for a fluoropolymer.
Common questions
What are the main types of fluoropolymers?
PTFE, PFA and FEP are fully fluorinated and have the broadest chemical resistance. ETFE and PVDF are partly fluorinated: stronger, stiffer and easier to process. PTFE is the only one of the five that cannot be melt-processed.
Are fluoropolymers PFAS?
Yes, under the broad definitions used by Minnesota, Maine and the proposed EU restriction, even though they are solid, stable plastics. As of October 2026 there is no U.S. federal ban on PTFE in industrial parts, and the proposed EU restriction has not been adopted: ECHA committees aim to finish their opinions by the end of 2026, and transition periods would follow any final rule. See our PFAS-free alternatives page for where the rules stand; this is not legal advice.
Which fluoropolymers can be injection molded?
PFA, FEP, ETFE and PVDF can all be injection molded and extruded. PTFE cannot: it is compression molded and sintered, ram extruded or paste extruded, and precision parts are usually machined. PVDF and ETFE are the easiest to mold; PFA and FEP need higher melt temperatures and hot molds.
Why do fluoropolymers need special processing equipment?
Hot fluoropolymer melts, especially when overheated, release corrosive gases that pit standard tool steel. Molders use corrosion-resistant barrels, screws and mold steels, keep residence time short and exhaust the fumes, which can cause polymer fume fever.
