FEP wire is a type of wire that is insulated or sheated with fluorinated ethylene propylene (FEP) material. FEP is a fluoropolymer with excellent electrical features. It is resistant to chemicals and can withstand a range of temperatures. FEP insulated wire is made in a similar manner to PVC, which means that FEP can be used for longer distances of wiring. Fep hook up wire is available in conductor types of roughly pure silver plated copper, nickel plated copper, bare copper, and tinned copper.
FEP thermocouple wire is a type of high temperature wire. that is commonly used in high-temperature locations such as steel mills, glass plants and boilers. Also, FEP cable can be used in some industrial high-temperature environments where abrasion and moisture resistant electrical wires are needed. FEP cable give these high temperature places a more stable current transmission work.

FAQ About FEP Cable
Fep Wire vs PTFE: What’s the difference?
FEP wire and PTFE wire(Polytetrafluoroethylene) are both types of electrical wires that offer high-performance insulation properties. As below is the differences
1.Composition: FEP (Fluorinated Ethylene Propylene) is a copolymer made of hexafluoropropylene and tetrafluoroethylene, while PTFE is a homopolymer made of tetrafluoroethylene. Both polymers are part of the fluoropolymer.
2. Temperature Resistance: FEP wire has a lower maximum continuous operating temperature compared to PTFE coat wire. Fep insulated thermocouple wire typically has a temperature rating of around 200°C (392°F), while ptfe insulated wire can handle temperatures up to 260°C (500°F). Higher temperature resistance makes PTFE suitable for more demanding applications.
3. Electrical Insulation Properties: Both FEP and PTFE offer excellent electrical insulation properties, including high dielectric strength and low dielectric constant.
4. Chemical Resistance: PTFE is well renowned for having a remarkable level of chemical resistance. Chemicals like acids and bases are not very corrosive to ptfe lead wire.FEP also offers good chemical resistance.
5. Flexibility: FEP is generally more flexible than PTFE.
6. Cost: PTFE often costs more than FEP.
What is FEP insulation?
FEP insulation refers to the use of fluorinated ethylene propylene (FEP) material for the insulation of electrical wires. This material is a thermoplastic polymer with excellent electrical conductivity and heat resistance. FEP insulation is commonly used in industries such as electronics, telecommunications, and automotive, where reliable electrical insulation is essential. It is often employed in wiring, cables, and connectors to provide protection and insulation for conductive elements.
Fep wire vs silicone wire
FEP wire and silicone wire are two types of high-temperature wires that have different properties. Here are some differences between the two:
FEP Wire
FEP fluoroplastic cable has higher chemical resistance than silicone wire.
For applications requiring high temperature ratings or strong electrical properties, FEP fluoroplastic cable might be a cost-effective alternative to PFA.
FEP is preferred for sheath material because it is non-flammable, has good outgassing characteristics, is the most flexible of all insulations, and has good weatherability.
Silicone Wire
Silicone rubber is more resistant to high temperature than FEP fluoroplastic cable, which will melt when exposed to high temperature.
Silicone wire and Teflon wire have their similarities, such as temperature and voltage ratings. But there are also differences that make silicone wire more special. Silicone is one of the softest insulating materials, easier to separate than PTFE, and has good resistance to moisture, ozone and UV radiation. But PTFE wire is smaller and easier to route than silicone wire. And the conductor becomes less flexible and more difficult to handle when silicone is used.
