Aerospace
Choosing between PTFE, FEP for aerospace heat shrink tubing and cable protection or ETFE and PEEK for fluid handling of different kind isn’t arbitrary—they each support different performance needs across aircraft, avionics, and other demanding aerospace environments. The right choice depends on temperature, abrasion, flexibility, chemical exposure, weight, and long-term reliability.
Select the perfect material for your application:
ETFE
Why use it:
- Outstanding toughness → very high abrasion, cut-through, and wear resistance.
- Lightweight with strong thin-wall capability.
- Good chemical resistance and electrical insulation.
- A strong fit for aerospace customers looking for durable, lightweight protection in high-wear environments.
Typical use case:
Aircraft wire harness protection, cable insulation, and lightweight tubing where durability is a key buying factor.
PTFE
Why use it:
- Extreme temperature resistance.
- Excellent chemical resistance.
- Very low friction → useful where smooth flow or easy cable movement matters.
- Strong electrical insulation performance.
Commercial value:
A premium option for aerospace programs where performance and reliability outweigh material cost.
Typical use case:
High-temperature aerospace tubing, liners, and demanding insulation applications.
FEP
Why use it:
- More flexible and transparent than PTFE.
- Very good chemical resistance.
- Good dielectric properties.
- Melt-processable, which supports precision extrusion and thin-wall tubing.
Commercial value:
A versatile option for customers seeking a balance of performance, manufacturability, and design flexibility.
Typical use case:
Lightweight tubing, cable insulation, and applications where flexibility or visibility adds value.
PEEK
Why use it:
- Excellent strength-to-weight ratio.
- High temperature capability.
- Very strong abrasion and wear resistance.
- Suitable where aerospace applications need both structural and environmental performance.
Commercial value:
A high-end material for specialized aerospace applications where customers are prepared to invest in performance-critical solutions.
Typical use case:
Advanced aerospace components, high-performance wire coatings, and demanding technical tubing.
FEP & PTFE Heat Shrink
Why use it:
- No flames or smoke in case of overheating (UL94 V0).
- Good insulation properties for cables, even in contact with fuel and hydraulic fluid.
- Very good temperature performance in both very cold and hot environments (+260ºC to -200ºC).
- Good dielectric properties.
- Standard sizes available especially for Aerospace wire and cable applications.
Commercial value:
A safe option for customers seeking a proven trustworthy performance in all environments, good manufacturability, and design flexibility.
Typical use case:
Aerospace wire and cable harnesses, high speed & frequency data transmission, sensor encapsulations in hazardous fluids.
