Tefzel™ ETFE 750
Fluoroplastic Resin

200 °C (392 °F) Appliance Wire Insulation

Product Information
Tefzel™ fluoroplastic resin,a close relative of Teflon™
fluoroplastic resin, wasintroduced in 1972. It
has been used to insulate
many millions of feet ofcable for aircraft and otheraerospace vehicles, rapidtransit cars, computers,automobiles, factories,
heating piping systems,
and nuclear power plants.
Now, a special grade ofTefzel™ resin is available
to provide this provenperformance for 200 °C(392 °F) appliance wire.

Advantages of Tefzel™ ETFE 750• Easily stripped and terminated• Unlike SF2 and SF1, it is so tough it doesn’t needa protective glass braid. Eliminating the glass braidmeans:– No irritating glass fibers– No glass strands to make terminations unreliable– Less stripping die wear
– No braid to damage; thus, spoiling wire
– No lacquers to smoke, crack, or turn brown with heataging• Superior fire resistance, thermal stability, andresistance to aging• Colorable, printable, and strippable• A pure polymer; not a compound with inconsistentcomposition and performance

UL and CSA Ratings

Cost-Effectiveness

UL Subject 758 and CSA 210 rated at 200 °C (392 °F):

• Single thin-wall extrusion, 40% smaller OD than SF2• UL Style 10109 for 300V

• Compatible with bare copper conductor per UL
requirement; expensive plated conductor not required• UL Style 10086 for 600V
Styles 10109 and 10086 are UL-approved for barecopper conductors at 200 °C (392 °F), as long as theindividual strand diameter is 15 mil and larger.

Tefzel™ ETFE 750 vs. Other Grades of Tefzel™ ETFE
• Tefzel™ ETFE 750 has 200 °C (392 °F) thermal rating
for appliance wire, while all other grades are lower.
• Tefzel™ ETFE 750 is more flexible than the othergrades; for example, flexural modulus for Tefzel™ ETFE
750 is 641.1 MPa (93,000 psi) vs. 1,171.9 MPa(170,000 psi) for Tefzel™ ETFE 200.

Other Properties of Tefzel™ ETFE 750• Stripping: Use automated or manual machines withstripping die blades or with radial V-blades.
• Termination: AMP Inc. has designed Faston* terminals
sized especially for Tefzel™ ETFE 750. Part numbers:
61375-1 tin-plated brass (cold side)63688-1 nickel-plated steel (hot side)
Terminals designed for silicone-coated wire can also
be used.
• Hot Stamp Printing: Use printing foils designed forTefzel™ resin, such as Kingsley Machine Inc. K-520
foil. Use temperatures between 163 °C (325 °F) and204 °C (400 °F) with moderate dwell and pressure.
