PTFE Coated Fiberglass Tape (PTFE Glass Cloth Tape / Non-Stick Heat Sealer Tape / Silicone Adhesive PTFE Fabric Tape) – For Packaging, Hot Presses & Industrial Liners

1. Product Overview

Nomay PTFE Coated Fiberglass Tape is a high-temperature, pressure-sensitive industrial tape made from woven fiberglass cloth impregnated and coated with PTFE, then coated on one side with high-temperature silicone adhesive.

The woven fiberglass backing provides tensile strength, tear resistance, puncture resistance and dimensional stability. The PTFE working surface provides low friction, non-stick release, moisture resistance and resistance to many industrial chemicals. The silicone pressure-sensitive adhesive allows direct installation on properly prepared machinery and metal surfaces.

The tape is designed for heat sealer jaws, heating plates, packaging equipment, hot presses, guide rails, chutes, rollers, composite molds and industrial surfaces where sticking, friction, heat and mechanical wear can interrupt production.

2. Product Construction

• Working surface: Smooth, non-stick PTFE coating
• Reinforcement layer: High-density woven fiberglass cloth
• Adhesive layer: High-temperature silicone pressure-sensitive adhesive
• Standard adhesive configuration: Single-sided
• Standard roll construction: Self-wound
• Optional construction: Release-liner-backed roll for die cutting and precision placement
• Typical colors: Brown or black, depending on construction
• Available formats: Slit rolls, sheets, strips and custom die-cut parts

The woven backing stabilizes the tape under tension and repeated machine movement. The PTFE coating creates the functional release surface, while the silicone adhesive secures the tape to the equipment.

3. Backing & Adhesive System

The woven fiberglass cloth reinforces the PTFE coating and provides better tensile strength, resistance to tearing, puncture resistance and dimensional stability than an unsupported PTFE film of similar thickness. This makes the tape suitable for heat sealers, rollers, guide rails and machine components exposed to repeated contact or mechanical wear.

The PTFE surface helps prevent molten plastic, adhesive, resin, ink and processed materials from sticking to equipment. It also provides a low-friction working face that supports smoother movement of films, fabrics and components.

The high-temperature silicone pressure-sensitive adhesive provides bonding across a wide temperature range. Adhesion depends on surface cleanliness, substrate type, application pressure, thermal cycling and operating load. Plasticized, contaminated, textured or low-surface-energy substrates must be tested before production use.

7. Application Scenarios / Problems Solved

Molten Film Sticking to Heat Sealer Jaws

Packaging film can melt and adhere to heated sealing jaws, causing weak seals, dirty sealing surfaces and production stoppages. The PTFE working surface creates a non-stick barrier that helps the film release more consistently.

Adhesive and Resin Buildup

Adhesive, resin, ink and coating materials can accumulate on rollers, plates, guides and process machinery. The low-surface-energy PTFE coating helps reduce buildup and makes equipment cleaning easier.

Friction on Guide Rails and Chutes

Films, fabrics and processed materials can drag, wrinkle or mark when moving across rough machine surfaces. The low-friction PTFE face provides a smoother sliding surface.

Tape Tearing During Machine Operation

Unsupported PTFE film can stretch or tear under mechanical load. The woven fiberglass reinforcement provides greater dimensional stability, tear resistance and puncture resistance for repeated industrial movement.

Frequent Maintenance and Manual Cutting

Standard slit widths and custom die-cut parts allow maintenance teams to replace worn tape in repeatable sizes. This reduces manual trimming, positioning errors and installation time.

9. Performance & Operating Conditions

The stated continuous working-temperature range is −70°C to 260°C. Short-term exposure up to 300°C must be evaluated according to exposure time, substrate, adhesive condition, mechanical load and airflow.

PTFE must not be heated above 316°C because excessive heating can release hazardous decomposition fumes. The tape must not be exposed to open flame or uncontrolled heating.

Before installation, clean the application surface and remove oil, grease, moisture, dust, release agents and loose contamination. Apply the tape using firm and uniform pressure while avoiding wrinkles, trapped air and unnecessary overlap.

For heat-sealing jaws, rollers and hot-press plates, verify the selected thickness under the actual temperature, pressure, speed and wear conditions. Sharp edges should be rounded where possible because repeated cutting or abrasion at one point can shorten tape life.

The PTFE surface provides resistance to many chemicals, but chemical exposure can also affect the exposed tape edges, fiberglass backing and adhesive. Test the complete tape construction when acids, alkalis, solvents, oils or cleaning agents are present.

10. Comparison & Selection Guide

0.13 mm Version

Choose 0.13 mm for general heat-sealer protection, precision wrapping, smoother step transitions and applications requiring lower profile and better conformability.

0.18 mm Version

Choose 0.18 mm for a balance of wear resistance, strength, flexibility and general industrial performance. It is suitable for common packaging machines, guide rails and hot-press applications.

0.25 mm Version

Choose 0.25 mm for heavier mechanical contact, increased puncture resistance, guide rails, chutes and applications where longer wear life is more important than a low-profile surface.

PTFE Fiberglass Tape vs Pure PTFE Film Tape

Choose PTFE-coated fiberglass tape when strength, dimensional stability, puncture resistance and wear resistance are important. Choose pure PTFE film tape when a smoother, fiber-free and more conformable surface is required.

Self-Wound vs Liner-Backed

Choose self-wound tape for direct roll installation and routine equipment maintenance. Choose liner-backed tape for precision die cutting, part organization and accurate positioning.

Full-Adhesive vs Zone Tape

Choose full-adhesive PTFE fiberglass tape for complete surface bonding. Choose PTFE zone tape when the heating center must remain adhesive-free and adhesive is required only along selected edges.

11. Technical Notes + FAQ

Q: Is this plumbing thread-seal tape?
A: No. This is an industrial PTFE-coated fiberglass adhesive tape for heat sealers, packaging machinery and process equipment. It is not unsupported PTFE thread-seal tape.

Q: What is the standard adhesive?
A: The standard adhesive is high-temperature silicone pressure-sensitive adhesive.

Q: Which thickness should I choose?
A: Use 0.13 mm for lower-profile and more conformable applications, 0.18 mm for balanced general-purpose performance and 0.25 mm for heavier wear and puncture resistance.

Q: Can it operate continuously at 300°C?
A: No. The listed continuous operating range is −70°C to 260°C. A temperature of 300°C is a short-term peak condition that requires application testing.

A: Yes. Narrow rolls, wide rolls, sheets, strips and custom die-cut parts can be produced according to approved dimensions or drawings.

Q: Will the tape remove without adhesive residue?
A: The silicone adhesive is designed for high-temperature use and cleaner removal, but actual removal depends on the substrate, exposure temperature, service time, pressure and surface condition.

Q: What information is required for a quotation?
