Skived PTFE Film Adhesive Tape

Skived PTFE film adhesive tape is made from a thin, unsupported PTFE film coated with a pressure-sensitive silicone adhesive. Unlike PTFE-coated fiberglass tape, it contains no woven reinforcement, giving it a smoother surface, lower profile, and greater flexibility around curved or irregular parts. It is selected for release, anti-friction, chemical-isolation, insulation, and surface-protection applications where a clean PTFE contact layer is required.

Key Benefits

• Smooth release surface: PTFE helps reduce sticking from resins, adhesives, plastics, inks, and process residues.
• Low-friction performance: suitable for guides, chutes, rails, rollers, and sliding contact points.
• Conformable unsupported film: wraps small diameters and follows curved surfaces more easily than reinforced cloth tape.
• Chemical resistance: PTFE provides broad resistance to many industrial chemicals; the complete tape must still be checked for the actual chemical and exposure conditions.
• High-temperature adhesive system: silicone adhesive supports elevated-temperature processing when the correct grade is selected.

Typical Applications

• Composite molding and release surfaces
• Rubber and plastic extrusion equipment
• Roller, guide rail, chute, and sliding-surface wrapping
• Packaging and laminating machinery
• Chemical-processing surface protection
• 3D-printer build surfaces and workshop fixtures, subject to process testing
• Electrical insulation where an approved grade and verified dielectric value are specified

PTFE Film Tape or PTFE Fiberglass Tape?

Choose skived PTFE film tape when you need a smooth finish, low profile, chemical isolation, or conformity around a curved part. Choose PTFE-coated fiberglass adhesive tape when reinforcement, dimensional stability, and repeated abrasion resistance are more important. For heat-sealing bars and heavily cycled machine surfaces, reinforced tape is often the more durable starting point; for rails, molds, and precision surfaces, unsupported film may provide the cleaner finish.

Selection Guidance

Specify the operating temperature, surface material, radius or part geometry, contact pressure, sliding speed, chemical exposure, and required service life. Thin grades conform easily and minimize buildup, while thicker grades generally provide more physical separation and longer wear life. Adhesion should be evaluated on the actual substrate because surface energy, contamination, roughness, and heat history affect bond strength.

For chemical, food-equipment, aerospace, or electrical use, identify the required test standard and documentation before ordering. PTFE chemistry alone does not confirm that every adhesive construction is suitable for every regulated application.

Customization and Ordering

Mavis supplies slit rolls, wide rolls, sheets, and die-cut parts. Provide the required width, length, thickness, quantity, substrate, process temperature, and application drawing where available. Samples can be used to confirm release, wear, adhesion, and removal performance before production quantities are converted.

Frequently Asked Questions

Is this tape reinforced?

No. The backing is skived PTFE film without woven fiberglass, so it is smoother and more conformable but less resistant to tearing than reinforced PTFE cloth.

Can it be removed cleanly?

Removal depends on the substrate, temperature, pressure, and exposure time. For critical surfaces, test a sample under real operating conditions.

Can it be used as electrical insulation?

Some grades can support insulation applications, but dielectric strength and compliance must be confirmed for the selected construction. For dedicated insulation requirements, also review our PTFE electrical insulation tape.
