High-Speed Data & Coaxial Cable
Use FEP when you need clean melt extrusion, stable insulation thickness and reliable electrical performance.
Likely fit: FEP
Wire & Cable Application Guide
Choose the right fluoropolymer for wire and cable insulation
Start with the cable you are making, the temperature it must survive, and how it will run on your extrusion line. Peflon helps cable manufacturers match FEP, ETFE, PFA and PTFE grades to real production conditions.

Match the material to the cable job
No single fluoropolymer is best for every cable. The right grade depends on dielectric needs, temperature, flexibility, flame requirements, chemical exposure and how thin the insulation wall will be.
Automotive & EV Cable
Use ETFE where thin walls, abrasion resistance and outdoor durability are part of the design target.
Likely fit: ETFE
Heating & Ignition Wire
Use FEP or PFA depending on continuous service temperature, chemical contact and final cable testing.
Likely fit: FEP / PFA
Sleeving, Tape & Paste Extrusion
Use PTFE fine powder when the process is paste extrusion or when the design needs PTFE insulation behavior.
Likely fit: PTFE
Product Selector
How to choose FEP, ETFE, PFA or PTFE for cable production
Use this table as a first pass. For final selection, send your cable structure and processing notes so the grade can be checked against your line and test standard.
| Cable Need | Recommended Path | Why It Fits | What to Confirm |
|---|---|---|---|
| Coaxial, LAN, plenum, tray and control cable | FEP for cable / wire | Melt-processable resin with MFR options from 2.0 to 32 g/10 min and service temperature from −80 to 200 °C. | Conductor size, wall thickness, line speed, target MFR and flame / smoke requirement. |
| Automotive, EV, sensor and outdoor cable | ETFE resin | Good mechanical strength, abrasion resistance and weatherability for thin-wall cable designs. | Flex life, abrasion target, color, voltage rating and automotive standard. |
| High-temperature or chemical-exposed cable | PFA resin | Useful when the design needs higher long-term temperature resistance, chemical resistance or purity. | Operating temperature, chemical media, jacket thickness and processing temperature window. |
| PTFE sleeving, tape, hose and coaxial paste extrusion | PTFE fine powder | Chosen for PTFE paste extrusion and insulation parts where melt extrusion is not the process. | Reduction ratio, lubricant system, preform size and sintering conditions. |
| Low-density dielectric or lightweight insulation | Foamed FEP resin | Used when the cable design needs lower weight or controlled foamed insulation structure. | Foaming method, target density, dielectric target and extrusion setup. |
Before Quotation
Send these 3 details and the recommendation gets much better
A cable grade cannot be chosen only from a product name. These details help avoid wrong MFR, unstable extrusion and failed trials.
-
Cable Structure
Tell us the cable type, conductor size, insulation or jacket thickness, and whether the part is solid or foamed.
-
Production Line
Share extrusion temperature range, screw information, target output, current grade if any, and the problem you want to solve.
-
Working Conditions
List temperature, chemicals, flexing, abrasion, flame / smoke standard and any REACH, RoHS or customer document request.
Material Selection Discipline
What Peflon checks before naming a grade
We do not treat wire and cable as one bucket. A grade that runs well on thick jacketing may not be the right answer for thin-wall insulation or high-speed data cable.
MFR & Melt Strength
For FEP cable extrusion, the resin must match wall thickness, output and drawdown. Too low or too high can both create problems.
Temperature & Environment
FEP covers many cable jobs. PFA or ETFE may be better when the design pushes heat, chemicals, abrasion or outdoor service.
Finished Cable Testing
Resin data helps selection, but flame, smoke, voltage and flex tests depend on the full cable construction.
Sampling & Documents
Samples, TDS, SDS and compliance documents can be prepared before your plant trial.

FAQ
Questions cable buyers usually ask first
What is the best fluoropolymer for wire and cable insulation?
For many extrusion jobs, FEP is the first material to check because it is melt-processable and widely used in cable insulation and jacketing. ETFE, PFA or PTFE may be better depending on abrasion, temperature, chemical exposure and processing method.
How do I choose the right MFR for FEP cable extrusion?
Start with the wall thickness, conductor size, line speed and drawdown ratio. A higher MFR is not automatically better. Share your current grade and extrusion conditions, and Peflon can suggest a closer starting point for trial.
Is FEP enough for automotive cable?
Sometimes yes, but ETFE is often checked for thin-wall automotive and EV cable when abrasion resistance and mechanical strength are important. The final choice depends on the cable standard and test plan.
Can Peflon match the grade we currently use?
Yes. Send the current grade name, TDS if available, target MFR, application and any trial issues. We can map a comparable Peflon grade and prepare samples for line testing.
