ETFE (Ethylene-Tetrafluoroethylene) delivers the greatest strength and abrasion resistance of the TFE copolymers and has a continuous service temperature range of 150°C [302°F].
FEP (Fluorinated Ethylene Propylene) is similar in chemical and physical behavior to PFA, but provides a lower service temperature at 200°C [392°F] and is slightly less susceptible to water absorption than most other fluoropolymers.
PFA (Perfluoroalkoxyethylene-Tetrafluoroethylene) is the most similar to PTFE in terms of chemical and physical behavior. PFA also has the added benefit of a higher service temperature of 260°C [500°F] over FEP.
Moldflon PTFE is PTFE that has had just enough Perfluoroalkoxy - groups added to convert it from a thermoset to a thermoplastic. It retains the properties of pure PTFE, most importantly including outstanding lubricity. It also offers excellent thermal stability with a continuous use maximum of 260°C [500°F].
PI (Polyimide) offers excellent dielectric strength as well as very good mechanical properties and chemical inertness. Unlike the above fluoropolymers, it is applied in multiple thin layers, so it bonds directly to the substrate. PI can also withstand very high temperatures with a continuous use maximum of 240°C [464°F], with resistance to short exposures to 400°C [752°F] with minimal generation of volatiles.

Alternate coatings will be considered upon request.
In order to provide you with a superior coated product it is recommended that the coatings be applied to round, shaped, stranded, or cabled wire. Coatings may be applied to all alloys that Fort Wayne Metals has to offer and are available in these colors: brown, gray, blue, white, red, green, purple, yellow, orange, and black. Additional colors available upon request.
Due to our in-house coating capabilities, we are able to streamline the manufacturing approach for your wire and cable needs. Fort Wayne Metals offers a fully integrated manufacturing option for our wire and cable customers by eliminating the inefficiencies associated with transferring material to multiple manufacturing sites.
Each of the coatings combines the chemical inertness of PTFE (polytetrafluoroethylene) with another polymer to provide melt forming capability and strength. The three fluoropolymers are used in a variety of medical device applications such as:
