Pure PTFE Film Tape (Skived PTFE Tape / Extruded PTFE Adhesive Tape / Fiberglass-Free High-Temperature Non-Stick Tape) – For Rollers, Heat Sealers, Molds & Electrical Insulation

1. Product Overview

Nomay Pure PTFE Film Tape is a single-sided industrial adhesive tape manufactured from integral PTFE film and heat-resistant silicone pressure-sensitive adhesive. It provides a smooth, fiberglass-free, non-stick, low-friction and electrically insulating surface for heated machinery, rollers, molds and precision industrial components.

Two principal film constructions are available: skived PTFE film and extruded PTFE film. Skived film offers greater conformability around curves and irregular surfaces, while extruded film provides improved flatness and reduced curling in lay-flat and roller applications.

This product is an adhesive-backed industrial PTFE film tape. It is not non-adhesive PTFE plumbing thread-seal tape and does not contain a woven fiberglass-cloth reinforcement layer.

2. Product Construction

The standard product consists of two functional layers:

• Working and backing layer: Integral skived or extruded pure PTFE film
• Bonding layer: Single-sided heat-resistant silicone pressure-sensitive adhesive

The standard construction is supplied as a self-wound roll. A release-liner-backed version can be selected for precision die cutting, sheet conversion, small parts and controlled positioning.

Black anti-static, pure white food-grade and color-specific versions use different formulations and must be selected separately when those functions are required.

3. Backing & Adhesive System

Skived PTFE film is produced by cutting a continuous thin film from a molded PTFE billet. It offers good flexibility and conformability for curved surfaces, irregular parts and applications requiring elongation.

Extruded PTFE film is produced through a controlled extrusion process. It generally lies flatter, resists curling during unwinding and provides a more uniform surface for rollers, plates and lay-flat equipment applications.

The high-temperature silicone pressure-sensitive adhesive allows the tape to bond to properly prepared metals, engineering plastics, composite tools and equipment surfaces without heat activation.

The PTFE working surface resists many industrial chemicals, but complete chemical compatibility must consider both the PTFE film and the silicone adhesive.

5. Applications

Recommended applications include industrial roller wrapping, web-processing rollers, heat-sealer jaws, sealing bars, packaging-machine plates, guide rails, chutes, sliding surfaces, precision molds, composite-molding tools, wire harnesses, motors, transformers, electronic fixtures, PCB-processing equipment, insulating pads and custom non-stick die-cut components.

6. Industries

Suitable industries include flexible packaging, heat-sealing machinery, web processing, printing, textiles, electronics manufacturing, PCB production, electrical equipment, composite molding, plastic and rubber processing, industrial automation, precision die cutting, appliance manufacturing and machinery maintenance.

7. Application Scenarios / Problems Solved

On rollers and web-processing equipment, the low-friction PTFE surface supports smoother material movement and helps reduce sticking, drag, squeaks and product scratching.

On heat-sealer jaws and packaging plates, the non-stick surface helps reduce melted-film and adhesive buildup, supporting cleaner equipment and easier maintenance.

On molds and composite tools, the PTFE surface provides a replaceable release interface that helps reduce resin adhesion and simplifies mold cleanup.

On guide rails, chutes and sliding surfaces, the tape helps reduce friction, wear and process-material accumulation.

In electronics and electrical equipment, the fiberglass-free film provides a clean insulating barrier without woven texture or loose glass fibers.

For precision converting, the release-liner-backed version supports stable die cutting, storage and accurate placement of small parts.

9. Performance & Operating Conditions

Apply the tape to a clean, dry and oil-free substrate. Remove dust, rust, resin, release agents and loose particles before installation. Use firm and uniform pressure to obtain complete adhesive contact.

For roller wrapping, control the tape tension and maintain consistent overlap or butt-joint spacing. Excessive installation tension can cause film stretching, edge lifting or seam movement during temperature cycling.

Skived film is more conformable but may curl or stretch more during handling. Extruded film generally lies flatter but may be less conformable on tight curves and complex shapes.

Continuous exposure near the maximum temperature may shorten silicone-adhesive life. Actual performance depends on the substrate, load, pressure, temperature cycle, chemical exposure and application duration.

The PTFE surface resists many chemicals, but the silicone adhesive may respond differently. Test the complete tape construction when solvents, oils, acids, alkalis or aggressive cleaning agents are present.

Do not expose PTFE film to temperatures above 316°C because hazardous thermal-decomposition fumes may be generated.

10. Comparison & Selection Guide

Choose skived PTFE film tape when flexibility, elongation and conformability around curves, corners or irregular surfaces are priorities.

Choose extruded PTFE film tape when improved flatness, reduced curling and uniform roller or plate coverage are priorities.

Choose PTFE-coated fiberglass cloth tape when greater tensile strength, puncture resistance, dimensional stability and heavy abrasion resistance are required.

Choose pure PTFE film tape when the smoothest surface, thinnest profile, electrical insulation and freedom from woven-glass texture are required.

Choose 0.05 mm or 0.08 mm for thin masking, curved surfaces and precision electronics. Choose 0.13 mm or 0.18 mm for additional durability and wear resistance.

Select the separate food-grade white version when documented food-contact suitability is required. Select the separate black anti-static version when static-dissipative performance is required.

11. Technical Notes + FAQ

Q: Is this tape made from pure PTFE film?
A: Yes. The backing is integral PTFE film without woven fiberglass reinforcement.

Q: What is the difference between skived and extruded PTFE film?
A: Skived film offers greater flexibility and conformability. Extruded film generally provides better flatness and reduced curling during unwinding.

Q: Is this the same as PTFE thread-seal tape?
A: No. This product contains pressure-sensitive adhesive and is designed for industrial surfaces. Plumbing thread-seal tape normally has no adhesive.

Q: Does the tape contain fiberglass?
A: No. The standard pure-film construction is fiberglass-free.

Q: Can it be used for electrical insulation?
A: PTFE film provides useful electrical-insulation properties, but the buyer must verify the voltage, dielectric requirement, temperature and safety conditions of the final application.

Q: Can it be used continuously at 300°C?
A: No. The recommended continuous operating temperature is up to 260°C. The 300°C value applies only to short-duration exposure.

Q: Is the standard version food grade?
A: Not automatically. Buyers requiring food-contact documentation should select the separately specified food-grade white PTFE tape.

Q: Can custom die-cut parts be supplied?
A: Yes. The tape can be supplied as rolls, sheets, strips, pads, washers and custom die-cut components based on the buyer’s drawing.
