ETFE vs XL-ETFE vs PTFE: What’s best for wire circuit protection?

One reader of the blog asked Lectromec to compare products for wire circuit protection.  A couple of the common wire insulations on the market are based on the PTFE and ETFE polymers. PTFE (DuPont trade name Teflon®) is a fluorocarbon and is constructed with carbon and fluorine atoms, whereas ETFE is a carbon, fluorine, and […] Read more

An overview of the “Big 2” wiring insulations: PTFE and ETFE

Editors Note: Article updated August 29, 2014 Most aerospace wiring insulations on the market are based on the PTFE or ETFE polymers. These polymers have a high corrosion resistance and strength and excellent dielectric properties that make them perfect for use in aircraft and radio wiring. PTFE (DuPont trade name Teflon®) is a fluorocarbon and […] Read more
