We Work With The Best Manufactures To Give You The Best Solutions

Skived PTFE Film Tapes are the most conformable and have the highest elongation of any PTFE tape produced by AFC.

These tapes are manufactured by applying a silicone adhesive* to a skived PTFE film and are excellent for use in applications where stretch or conformity is desired. Pure PTFE film tapes, such as these, exhibit the best chemical, fire and weathering resistance of any tape in this series. In addition, these tapes have exceptional electrical properties and are ideal for wire and cable insulation and protection.

*Acrylic adhesive is available upon special request. Skived PTFE Tapes conform to Mil Spec I-23594C Type I, have received USDA approval for food processing and handling, are FDA compliant (21 CFR177.1550), and are suitable for applications with operating temperatures ranging from -100°F to 500°F (-73°C to 260°C).

    Disclaimer:

    All figures provided in the above table are based upon ASTM D 4969-97, the Standard Specification for Polytetrafluoroethylene (PTFE) Coated Glass Fabric. The above tensile values are based upon the ASTM D902 test method and are not actual values of AFC's materials. The above tensile values are 80% of the figures provided in Table 6 of specification D579. AFC states that its actual tensile will be greater than the above material specification and that actual tensile values will be provided upon request. AFC measures adhesion according to ASTM D 3654/D 3654M, Standard Test Methods for Shear Adhesion of Pressure-Sensitive Tapes, and actual adhesion values will vary. Edge Tear values are based upon ASTM D1424 (Elmendorf Tearing Test) and are average values that can vary.
