PTFE Tape with Silicone Adhesive (Silicone Adhesive PTFE Tape / High-Temperature Non-Stick Tape / Heat Sealer Tape) – Pure Film or Fiberglass for Packaging, SMT & Hot Presses

1. Product Overview

Nomay PTFE Tape with Silicone Adhesive is a high-temperature industrial adhesive tape combining a low-friction, non-stick PTFE working surface with heat-resistant silicone pressure-sensitive adhesive.

Two primary backing constructions are available. The PTFE-coated fiberglass cloth version provides greater tensile strength, dimensional stability, puncture resistance and wear resistance. The pure PTFE film version provides a smoother, more conformable and fiberglass-free surface for precision or clean processing.

The tape is designed for heat sealer jaws, heating plates, sealing bars, packaging machines, SMT fixtures, hot-press equipment, web-processing rollers, guide rails, chutes, composite molds and other heated industrial surfaces.

2. Product Construction

• Working surface: Non-stick, low-friction PTFE
• Backing option 1: PTFE-coated woven fiberglass cloth
• Backing option 2: Pure PTFE film
• Adhesive layer: High-temperature silicone pressure-sensitive adhesive
• Adhesive configuration: Single-sided
• Standard roll construction: Self-wound
• Optional construction: Release-liner-backed roll
• Processing options: Precision slitting, fixed-length cutting, sheeting and die cutting
• Color options: Brown, white, grey or black

The PTFE surface provides release and low friction. The selected film or fiberglass backing provides the required strength, smoothness or wear performance, while the silicone adhesive secures the tape to the application surface.

3. Backing & Adhesive System

PTFE-Coated Fiberglass Cloth Version

The fiberglass cloth version provides higher tensile strength, resistance to tearing and puncture, dimensional stability and better resistance to repeated mechanical wear. It is suitable for heat-sealing machinery, rollers, guide rails, chutes and equipment surfaces exposed to repeated contact.

Pure PTFE Film Version

The pure PTFE film version provides a smoother surface, improved conformability and a fiberglass-free construction. It is suitable for precision equipment, electronic fixtures, web handling, electrical protection and applications where fabric texture or loose fibers are undesirable.

Silicone Adhesive System

The high-temperature silicone pressure-sensitive adhesive provides bonding across a wide temperature range and supports installation on properly cleaned metal and industrial surfaces. Actual adhesion and removal depend on the substrate, surface condition, application pressure, temperature, service time and mechanical load.

Silicone adhesive should not be selected without evaluation where silicone transfer could interfere with later painting, coating, printing or structural bonding.

7. Application Scenarios / Problems Solved

Molten Film Sticking to Heat Sealer Jaws

Packaging film can melt and adhere to heated jaws, causing weak seals, equipment contamination and production interruptions. The PTFE surface provides a non-stick barrier that helps the film release from the heated surface.

Adhesive and Resin Buildup

Adhesive, resin, ink or coating materials may accumulate on rollers, hot-press plates and machine surfaces. The low-surface-energy PTFE working face helps reduce buildup and cleaning difficulty.

Friction on Rollers and Guide Rails

Films, fabrics and components may drag, wrinkle, mark or create noise when moving over rough surfaces. The low-friction PTFE face creates a smoother sliding surface.

Wear and Puncture on Machinery

For repeated mechanical contact, the PTFE-coated fiberglass version provides better tensile, puncture and wear resistance than unsupported PTFE film.

Precision or Fiber-Free Processing

Where a smooth surface, close conformability or fiberglass-free construction is required, the pure PTFE film version avoids woven texture and loose glass fibers.

Difficult Die Cutting and Positioning

A release-liner-backed construction stabilizes the adhesive tape during precision die cutting and protects the adhesive before installation.

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 the exposure time, backing, adhesive condition, substrate, 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 application, remove oil, moisture, dust, release agents and loose contamination from the substrate. Apply the tape using firm and uniform pressure, and avoid wrinkles, trapped air and unnecessary overlap.

For rotating rollers, heat-sealing jaws, hot-press plates and repeated thermal cycling, test the selected backing and thickness under actual production conditions.

Chemical resistance is mainly provided by the exposed PTFE surface. Chemicals can still contact and affect the adhesive or exposed tape edges, so the complete tape construction must be tested for chemical-processing applications.

10. Comparison & Selection Guide

Pure PTFE Film vs PTFE Fiberglass Cloth

Choose pure PTFE film when the application requires a smoother surface, greater conformability, no glass fibers or reduced fabric texture. Choose PTFE-coated fiberglass cloth when higher tensile strength, dimensional stability, puncture resistance and wear resistance are required.

Thin vs Thick Construction

Choose 0.05 or 0.08 mm for narrow positions, curved surfaces and lower-profile applications. Choose 0.13 or 0.18 mm for general machinery, heat sealing and balanced performance. Choose 0.25 mm where increased wear and puncture resistance are required.

Self-Wound vs Liner-Backed

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

Silicone Adhesive vs Acrylic Adhesive

Choose silicone adhesive for high-temperature machinery and wide-temperature performance. Acrylic adhesive may provide different initial bonding behavior at lower temperatures but is not the standard construction for this product.

Full-Adhesive vs Zone Tape

Choose full-adhesive PTFE tape when the complete backing must bond to the machine surface. Choose PTFE zone tape when the central heating area must remain adhesive-free.

11. Technical Notes + FAQ

Q: Is this the same as silicone rubber self-fusing tape?
A: No. This product uses a PTFE working surface and silicone pressure-sensitive adhesive. Silicone rubber self-fusing tape is a different product used mainly for wrapping and sealing.

Q: Which backing should I choose?
A: Choose PTFE-coated fiberglass cloth for higher strength, dimensional stability and wear resistance. Choose pure PTFE film for a smoother, fiber-free and more conformable surface.

Q: Can the tape operate continuously at 300°C?
A: No. The continuous working range is −70°C to 260°C. A temperature of 300°C is a short-term peak condition requiring application testing.

Q: Is a release liner available?
A: Yes. The tape can be supplied as a self-wound roll or with a release liner for die cutting and precision placement.

Q: Can the product be custom slit or die cut?
A: Yes. Custom widths, lengths, sheets, strips and die-cut parts can be produced according to approved dimensions or drawings.

Q: Does the tape provide electrical insulation?
A: PTFE has electrical-insulation properties, but the complete tape must be tested when a specific dielectric strength, voltage rating or insulation class is required.

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

Q: What information is required for a quotation?
A: Please provide the backing type, thickness, width, roll length, color, liner requirement, operating temperature, equipment type, application surface and order quantity.
