PTFE-Coated Carbon Fiber Fabric Tape (Carbon Fiber PTFE Tape / PTFE Carbon Cloth Tape / High-Strength Non-Stick Tape) – For Composite Molds, Wear Surfaces & Industrial Tooling

1. Product Overview

Nomay PTFE-Coated Carbon Fiber Fabric Tape is a specialty industrial adhesive tape manufactured from woven carbon-fiber fabric treated with a low-friction PTFE coating and coated on one side with heat-resistant silicone pressure-sensitive adhesive.

The carbon-fiber carrier provides high tensile strength, dimensional stability, low weight and improved resistance to repeated flexing. The PTFE working surface provides non-stick release and reduced friction, while the silicone adhesive allows the material to be installed on molds, tools, plates, guides and other industrial components.

This is a carbon-fiber-reinforced PTFE tape. It is different from black anti-static pure PTFE film tape, standard PTFE-coated fiberglass tape and PTFE-coated aramid fabric tape.

2. Product Construction

The standard product consists of three functional layers:

• Working surface: Black or dark-grey low-friction PTFE coating
• Reinforcement layer: Woven carbon-fiber fabric
• Bonding layer: Single-sided heat-resistant silicone pressure-sensitive adhesive

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

3. Backing & Adhesive System

The woven carbon-fiber carrier provides a high strength-to-weight ratio and dimensional reinforcement. Compared with fiberglass cloth, carbon fabric can provide greater stiffness and lower weight in an appropriately designed construction.

The PTFE coating covers the woven carbon-fiber surface and provides non-stick release, reduced surface friction, low moisture absorption and resistance to many industrial process materials.

The silicone pressure-sensitive adhesive bonds the reinforced PTFE material to properly prepared metal, composite, tooling-board and selected industrial surfaces. Actual adhesion depends on the substrate, surface energy, roughness, temperature, pressure and mechanical load.

4. Key Features & Buyer Benefits

5. Applications

Recommended applications include composite-molding tools, carbon-fiber molds, heated tooling plates, autoclave-tooling accessories, wear liners, machine guides, sliding surfaces, rollers, composite lay-up fixtures, resin-release surfaces, industrial mold repairs, conductive backing components and custom die-cut tooling pads.

6. Industries

Suitable industries include carbon-fiber composite manufacturing, aerospace-component processing, automotive composites, wind-energy components, sporting-goods production, industrial tooling, mold manufacturing, electronics, precision die cutting, industrial automation, printing, textiles and machinery maintenance.

7. Application Scenarios / Problems Solved

On composite molds and tooling, the PTFE surface provides a low-surface-energy release layer that helps reduce resin sticking and simplifies mold cleanup.

On heated tooling plates, the reinforced construction provides greater dimensional stability than unsupported PTFE film while maintaining a non-stick working surface.

On guide rails and sliding surfaces, the PTFE coating helps reduce drag, squeaks, abrasion and process-material buildup.

On carbon-composite tooling, the dark carbon-fiber construction can provide better visual integration than brown PTFE fiberglass cloth tape.

For worn or difficult-release mold areas, adhesive-backed PTFE carbon fabric can provide a replaceable release interface without rebuilding the complete tool surface.

For precision parts, a release liner supports accurate die cutting, storage and positioning of pads, strips and custom shapes.

9. Performance & Operating Conditions

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

When applying the tape to molds or tooling, plan seams away from critical cosmetic surfaces. PTFE tape seams may transfer visible lines to molded composite parts.

Carbon fiber is electrically conductive, but the PTFE coating and silicone adhesive can electrically isolate the carrier. The finished tape must not automatically be described as conductive or anti-static without measuring the complete construction.

If electrical conductivity or static dissipation is required, specify the target surface resistance, test method, grounding arrangement and required measurement location before production.

Continuous operation near the maximum temperature may shorten adhesive service life. Actual performance depends on temperature cycle, pressure, resin system, chemical exposure, mechanical load and installation quality.

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

10. Comparison & Selection Guide

Choose PTFE-coated carbon-fiber fabric tape when high strength, low weight, dimensional reinforcement, dark appearance and compatibility with carbon-composite tooling are important.

Choose PTFE-coated fiberglass tape for general heat-sealing, packaging and industrial release applications where cost efficiency, electrical insulation and broad availability are priorities.

Choose PTFE-coated aramid fabric tape when flexibility, toughness and repeated flexing are more important than stiffness or electrical conductivity.

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

Select the thinner 0.20–0.25 mm finished constructions for curved surfaces and precision parts. Select 0.30–0.40 mm constructions when greater stiffness, wear life and dimensional stability are required.

11. Technical Notes + FAQ

Q: Is this the same as black anti-static PTFE film tape?
A: No. This product uses woven carbon-fiber fabric as the reinforcing carrier. Black anti-static PTFE film tape uses a modified pure PTFE film without woven reinforcement.

Q: Is the complete tape electrically conductive?
A: The carbon-fiber carrier is conductive, but PTFE coating and silicone adhesive can isolate it. Conductivity or surface resistance must be measured on the complete finished construction.

Q: Can it be used as an electrical insulator?
A: It should not automatically be selected as an electrical-insulation tape because carbon fiber is conductive. Use PTFE fiberglass or pure PTFE film tape when dependable electrical insulation is the main requirement.

Q: Can it be used on composite molds?
A: Yes. The PTFE surface can provide a release interface for selected composite molds and tooling, subject to resin, temperature and surface-quality testing.

Q: Will tape seams appear on a molded component?
A: They may. Seams and overlaps can transfer visible lines to the finished part, so seam placement should be planned before installation.

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

Q: Can the tape be supplied with release paper?
A: Yes. Self-wound and release-liner-backed constructions can be supplied according to the converting and installation requirements.

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