PTFE Coated Glass Cloth Tape

PTFE Coated Glass Cloth Tape (T-710)

PTFE Fiberglass Tape (PTFE Adhesive Tape for Heat Sealing, Release Surfaces & High-Temperature Insulation)

Product Overview

PTFE Coated Glass Cloth Tape is a high-performance industrial adhesive tape made from woven fiberglass fabric coated with PTFE (polytetrafluoroethylene) and combined with a high-temperature silicone pressure-sensitive adhesive.

This construction combines the mechanical strength of fiberglass cloth with the non-stick and chemical resistance properties of PTFE, creating a tape that performs reliably in harsh industrial environments. The PTFE surface provides excellent release properties, low friction, and anti-adhesion performance, while the fiberglass reinforcement delivers superior tensile strength and dimensional stability.

Selected grades of PTFE Fiberglass Tape are commonly used in elevated-temperature applications up to approximately 260°C (500°F), depending on product grade, dwell time, substrate, and process conditions. It is widely used for heat sealing equipment, packaging machinery, composite processing, release surfaces, and sliding applications where conventional tapes would quickly fail.

PTFE Adhesive Tape is therefore a commonly selected solution for industries requiring high temperature resistance, release performance, and durable mechanical reinforcement.

Key Features & Benefits

• High Temperature Resistance
  Designed for demanding thermal environments, PTFE fiberglass tape is commonly used from low temperatures up to 260°C, depending on grade and application profile.
• Excellent Non-Stick Release Surface
  The PTFE coating creates a smooth, low-friction surface that prevents adhesives, plastics, and resins from sticking to machinery or tooling.
• Fiberglass Reinforced Strength
  The woven glass cloth backing provides high tensile strength and dimensional stability, helping the tape resist tearing and mechanical stress.
• Outstanding Chemical Resistance
  PTFE is resistant to most acids, alkalis, solvents, and industrial chemicals, ensuring long service life in aggressive production environments.
• Selected Electrical Insulation Uses
  With good dielectric properties and moisture resistance, selected grades of PTFE Fiberglass Tape can be used in electrical insulation applications. Suitability should be confirmed against the TDS and actual operating conditions.
• Smooth Low-Friction Surface
  The PTFE layer reduces friction and wear on moving mechanical parts, helping improve equipment efficiency and durability.

Typical Applications

PTFE Coated Glass Cloth Tape is widely used on heat sealing equipment, packaging machinery, release surfaces, rollers, chutes, sliding components, and other heated process equipment where non-stick performance, low friction, and mechanical strength are required.

Heat Sealing & Packaging Machinery

• Heat Sealing Bars: Prevents molten plastic from sticking to sealing jaws.
• L-Bar Sealers: Protective non-stick surface for shrink-wrapping equipment.
• Film Sealing Equipment: Suitable for PE, PVC, and other film sealing applications where a clean non-stick surface is needed on heated contact areas..

Release Surfaces, Rollers & Sliding Components

• Guide Rails & Chutes: Reduces friction and wear in automated lines.
• Rollers, Drums & Moving Contact Surfaces: Helps reduce buildup, drag, and wear in heated or adhesive-prone processes.
• Conveyor Components: Helps prevent material accumulation on moving parts.
• Laminating Equipment: Provides a stable non-stick release surface in heated processes.

Composite Processing & Mold Release

• Mold Release Surface: Helps prevent resins or composites from sticking during processing.
• Drying Drums & Heating Plates: Provides anti-adhesion protection for heated industrial surfaces.

Textile, Printing & Heated Process Equipment

• Drying Cylinders Protection
• Heat Press Machines
• Screen Printing Equipment Protection

Selected Electrical Insulation Uses

• Cable Wrapping in elevated-temperature environments
• Insulation for selected motor and transformer applications where dielectric performance is required

For applications such as L-bar sealing, packaging machinery, and selected form-fill-seal lines, T-710 provides a durable non-stick release surface with low friction and good dimensional stability.

PTFE glass cloth tape is used when heat sealing equipment needs both a non-stick release surface and stronger backing support under repeated heat, pressure and film contact. For continuous band sealers, L-bar sealers, heat press plates and packaging machinery, our Industrial Heat Sealing guide explains when reinforced PTFE glass cloth tape is preferable to PTFE film tape, and how thickness, backing strength, adhesive grade and wear resistance affect service life.
