PTFE Coated Fiberglass Tape (PTFE Glass Cloth Tape / Non-Stick Heat Sealer Tape

Product Specification

1. Product Overview

Nomay PTFE Coated Fiberglass Tape combines woven fiberglass reinforcement, a PTFE release surface and single-sided silicone pressure-sensitive adhesive.

Common names include PTFE Glass Cloth Tape, Non-Stick Heat Sealer Tape and Silicone Adhesive PTFE Fabric Tape.

This page focuses on reinforced industrial liners, surface-finish selection and converting formats for packaging machines, hot presses, guides and rollers. It is not plumbing thread-seal tape or unsupported PTFE film.

2. Product Construction

Backing: PTFE-coated woven fiberglass.
Adhesive: Silicone pressure-sensitive adhesive.
Adhesive side: Single-sided.
Standard color: Brown.
Standard format: Self-wound roll.
Optional format: Separately specified liner-backed roll.
Converted forms: Strips, sheets and liner-supported die-cut parts.

Overall thickness does not separately identify fiberglass, PTFE coating and adhesive thickness. A liner is removed before installation and must be excluded from installed-tape thickness unless a measurement explicitly states otherwise.

3. Backing & Adhesive System

Fiberglass reinforces the working surface and supports dimensional stability.

PTFE provides release and low friction. Weave, coating coverage and surface finish influence texture and wear.

Silicone adhesive attaches the tape to compatible equipment surfaces. Substrate condition, thermal cycle and load affect adhesion; silicone chemistry does not guarantee clean removal.

The reinforced backing is not automatically superior to every film grade under every wear condition.

4. Available Specifications

The supplied ordinary-construction ranges do not establish all liner-backed or modified versions. Confirm available size combinations and inventory.

5. Key Features & Buyer Benefits

• Reinforced release surface suits industrial lining.
• PTFE helps reduce resin, adhesive and film buildup.
• Low friction supports web and component movement.
• Replaceable liners protect contact surfaces.
• Thickness options address clearance and conformity.
• Surface selection helps control texture transfer.
• Custom conversion reduces onsite cutting.
• Liner-backed parts support accurate placement.

6. Application Procedure

Step 1 — Identify the equipment surface, contact material, location and finish requirements.

Step 2 — Select construction, thickness, width, length and roll or converted format.

Step 3 — Define continuous and peak temperatures, time, pressure, speed, chemicals and replacement requirements.

Step 4 — Prepare strips or parts to the drawing and plan edges, overlaps and roller seams.

Step 5 — Apply to clean, dry surfaces with uniform pressure, avoiding tension, bubbles and wrinkles.

Step 6 — Validate release, surface finish, adhesion, heat transfer and wear under actual production conditions.

7. Application Industries

• Packaging and heat-sealing machinery.
• Film converting and bag making.
• Printing, coating and laminating.
• Textile pressing and heat transfer.
• Plastics and resin processing.
• Composite tooling.
• Industrial machinery maintenance.
• Adhesive converting and die cutting.

8. Application Scenarios / Problems Solved

Hot-Press Liners
Cover suitable platens to reduce sticking. Confirm pressure, cure conditions and the required part finish. Woven texture may mark a surface-sensitive component.

Packaging Sealers
Provide release over suitable bars or jaws. Confirm dwell, pressure, cooling and actual tape temperature. Changing thickness can change sealing response.

Guide Rails and Chutes
Reduce drag and residue on contact areas. Confirm line speed, contact pressure and sharp edges. Abrasive particles can shorten life.

Roller and Turn-Bar Covers
Support release during web movement. Confirm diameter, seam design and adhesive holding under rotation.

Converted Wear Patches
Use defined shapes for repeated replacement. Confirm part dimensions, liner release and maintenance interval; conversion does not establish a wear-life guarantee.

9. Performance & Operating Conditions

Temperature
The supplied capability is 260–300°C, without defined exposure duration. Confirm continuous and peak conditions, cooling and service life; the range is not a continuous rating.

Adhesion
The supplied peel range is 0–1200 g. Confirm force convention, specimen width, method, substrate and dwell time.

Heat Transfer and Surface Finish
Thickness and coating influence process response. Greater total thickness does not automatically mean a thicker PTFE working layer or longer life.

Environment and Wear
Evaluate chemicals against adhesive and edges as well as PTFE. Inspect for exposed fibers, cracking and lifting.

Special Functions
Black does not automatically mean ESD. Direct food contact and electrical requirements need separate confirmation.

10. Comparison & Selection Guide

Choose fiberglass reinforcement for dimensional stability and an appropriate reinforced liner.

Choose PTFE film where woven texture is unacceptable.

Choose self-wound supply for direct installation and liner-backed supply for precision conversion.

Choose zone tape for an adhesive-free heating center or detectable tape for a separately validated inspection program.

Select thickness by geometry, thermal response and tested wear.

11. Important Selection Notes + Technical Notes / FAQ

A. Important Selection Notes

• Confirm size combinations and tolerances.
• Do not transfer ordinary parameters to special constructions.
• Temperature depends on time and load.
• Peel values need a defined test basis.
• Color does not establish antistatic performance.
• Residue-free removal and food-contact suitability are not automatic.

B. Technical Notes / FAQ

How does this differ from the brown self-wound page?
This page addresses industrial liner and converting selection; the brown page focuses on that supply format.

Is it thread-seal tape?
No. It is an adhesive-backed reinforced industrial material.

Does thicker tape always last longer?
No. Coating, load and operating conditions also matter.

Can it continuously operate at 300°C?
That rating has not been established.

Can it be die cut?
Use a separately specified liner-backed construction.
