PTFE-Coated Carbon Fiber Fabric Tape / Carbon Fibre PTFE Tape / PTFE Carbon

Product Specification

1. Product Overview

Nomay PTFE-Coated Carbon Fiber Tape, also called carbon fiber PTFE tape or PTFE carbon cloth tape, combines a woven carbon-fiber carrier with a PTFE working surface and single-sided silicone pressure-sensitive adhesive.

The spelling “carbon fibre PTFE tape” describes the same material category. The product provides a reinforced release and contact surface for compatible composite tooling, equipment covers and guide surfaces.

The exposed PTFE face supplies the non-stick interface, while the adhesive face attaches the material to the equipment. The carbon fabric forms the internal reinforcement.

This construction is different from black PTFE film tape, PTFE-coated fiberglass tape and PTFE-coated aramid tape. Black appearance alone does not identify the carrier or establish the finished tape's electrical performance.

2. Product Construction

The construction consists of:
- Working surface: PTFE coating.
- Reinforcement: Woven carbon-fiber fabric.
- Bonding layer: Silicone pressure-sensitive adhesive on one face.

The PTFE coating and carbon fabric form the coated carrier. Finished tape thickness includes that coated carrier and the adhesive layer.

Self-wound or release-liner-backed formats can be specified according to the selected construction and converting requirements. Any release liner is removed before bonding and service.

The exact weave, coating coverage and adhesive thickness affect handling and performance. They must not be assumed to be identical across all versions.

3. Backing & Adhesive System

Carbon-fiber fabric:
The woven carrier reinforces the tape and supports dimensional control during handling. Strength, stiffness and bending behavior depend on the fabric construction, direction and coating.

Do not assume that every carbon-fabric tape is more flexible, more wear resistant or more fatigue resistant than every fiberglass or aramid alternative.

PTFE coating:
The exposed coating provides release and reduced sliding friction for compatible process materials. Fabric texture may remain visible through the coating and can influence the finish of a contacted or molded part.

Silicone adhesive:
The adhesive secures the tape to suitably prepared tooling or equipment surfaces. Adhesion depends on material, roughness, contamination, temperature and mechanical loading.

For composite processes, assess whether silicone transfer could affect subsequent painting, coating or bonding of the molded component. The adhesive system must suit the complete manufacturing sequence.

4. Available Specifications

Specify the following for model selection:
- Carrier: Woven carbon-fiber fabric with PTFE coating.
- Adhesive: Silicone pressure-sensitive adhesive.
- Adhesive side: Single-sided.
- Color: Black or dark grey, according to the selected construction.
- Finished thickness: Coated carrier plus adhesive, excluding any release liner.
- Width: Required finished width and tolerance.
- Roll length: Required finished-roll length.
- Supply format: Roll, liner-backed roll, sheet, strip or die-cut part.

The supplied enterprise parameter database does not provide a separate numerical specification for this carbon-fabric construction. General PTFE silicone-tape ranges must not be automatically treated as confirmed carbon-fabric model data.

For thickness-critical applications, state the finished thickness requirement and identify whether a separate coated-carrier thickness is also needed.

For converted parts, provide dimensions, tolerances, liner requirements and fabric orientation where relevant. Final dimensions and performance values are recorded in the selected model specification.

5. Key Features & Buyer Benefits

- PTFE working face: Helps compatible resin or process material release from the contact surface.
- Low-friction surface: Can reduce sliding resistance on suitable guides and equipment covers.
- Woven carbon-fiber reinforcement: Supports handling and dimensional control within the tape construction.
- Single-sided adhesive: Allows the release material to be attached to an equipment surface.
- Replaceable cover format: Allows selected contact areas to be renewed during maintenance.
- Custom roll or part dimensions: Help match tooling geometry, coverage and installation requirements.

A replaceable release layer is not a structural mold repair. It does not restore the strength or accuracy of damaged tooling.

Release life, abrasion resistance and dimensional performance depend on the selected construction and actual process conditions.

6. Application Procedure

Identify the tooling material, resin system, curing cycle and required part finish before installation. Check that the selected tape suits the complete process.

Stop and isolate equipment where applicable and allow the mounting surface to cool. Remove resin deposits, old tape, loose particles and incompatible release-agent residue. Clean and dry the surface using an appropriate method.

Plan the tape layout before bonding. Place seams and overlaps away from finish-critical areas where possible, because tape edges and fabric texture may transfer to the molded surface.

Remove any liner and apply even pressure. Avoid wrinkles, trapped air, excessive tension and bridging over recesses. Do not stretch the tape to force it around an unsuitable geometry.

Confirm installation temperature and conditioning requirements for the selected adhesive. Trial the complete resin, temperature, pressure and dwell-time cycle before routine use.

Inspect the PTFE face and tape edges for wear, lifting and exposed fibers. Replace damaged material rather than treating it as a permanent tooling surface.

Store unused rolls or parts protected from contamination, heat and sunlight, following the supplied storage and shelf-life instructions.

7. Application Industries

Relevant industries include:
- Composite tooling and mold manufacture.
- Composite-component processing.
- Industrial guide and equipment-surface maintenance.
- Precision tape converting and tooling-part supply.

Aerospace, automotive and wind-energy manufacturing may involve suitable composite processes, but an industry name does not establish process qualification. Use the actual resin system, pressure, temperature and finish requirements for selection.

Autoclave, electrical, cleanroom and other specialized uses require their own applicable model data and process validation.

8. Application Scenarios / Problems Solved

Resin sticking to a tooling surface:
The PTFE face can provide a release interface for a compatible resin process. Evaluate resin release, surface finish and cleaning under the actual cure cycle.

A guide surface causing material drag:
A PTFE contact face can reduce sliding resistance where the equipment design and process material are suitable. Check adhesion and wear during representative operation.

A reinforced cover needed for handling:
The carbon fabric supplies a woven carrier rather than an unsupported film. Select according to the required fabric direction, flexibility and dimensions.

Localized contact areas needing replacement:
An adhesive-backed strip or pad can cover a suitable area without replacing the entire release surface. It cannot correct structural mold damage or underlying dimensional errors.

Surface marks appearing on molded parts:
Review seams, overlaps and fabric texture before production. A tape that releases successfully may still leave an unacceptable cosmetic impression.

Complex replacement shapes:
A dimensioned converted part can help control outline and placement. Include fabric orientation and liner presentation where these influence installation.

9. Performance & Operating Conditions

Temperature:
Confirm continuous temperature, peak temperature and exposure duration for the complete carbon-fabric, PTFE and silicone-adhesive construction. Carrier heat resistance alone does not establish the finished tape rating.

Do not use a generic -70°C to 260°C continuous range or 300°C peak as a confirmed specification for this model without matching data.

Electrical behavior:
Carbon fibers can provide a conductive path, but PTFE coating and adhesive can isolate the carrier. Conductive carrier material does not establish conductive adhesive, a conductive working face or a verified ESD surface.

For electrical requirements, specify the measurement location, test method, acceptance range and intended connection. Do not select this construction as a rated electrical insulator merely because it contains PTFE.

Mechanical behavior:
Assess bending radius, loading direction, pressure, wear and repeated movement using the selected construction. No numerical tensile or fatigue rating is assigned without applicable test data.

Peel performance:
Specify adhesive peel strength with specimen width, peel angle, speed, substrate and conditioning.

Resin and chemical compatibility:
Evaluate the complete tape against the resin system, cleaning agents and exposure cycle. Include downstream coating or bonding requirements when assessing possible material transfer.

10. Comparison & Selection Guide

Carbon fabric versus fiberglass:
Compare the required mechanical behavior, fabric texture and electrical considerations using actual model data. Carbon-fabric reinforcement does not automatically provide better wear life or release performance.

Carbon fabric versus aramid:
Select according to bending, handling and process requirements. Do not assume a stiffness or flex-life ranking without comparing the relevant constructions.

Reinforced fabric versus pure PTFE film:
Choose a fabric-backed version when the woven carrier suits the application. Consider a film version where fabric texture is undesirable, using the selected film's finish and mechanical data.

Adhesive tape versus another release system:
Tape provides a defined, replaceable contact layer but introduces edges, seams and thickness. Compare these effects with the finish and geometry required by the process.

Self-wound versus liner-backed:
A self-wound format may suit direct roll installation. A confirmed liner-backed format can support cutting, handling and placement of smaller parts.

Thickness selection:
Consider flexibility, clearance, surface impression and wear together. Compare coated-carrier thickness and finished tape thickness on their correct measurement bases.

11. Technical Notes + FAQ

Technical notes:
The order specification should identify the carbon-fabric construction, PTFE coating, adhesive, finished dimensions, process cycle and any required fabric orientation.

Q: Is this the same as black anti-static PTFE film tape?
A: No. This product uses woven carbon-fiber fabric as its carrier. A black PTFE film tape has a different backing structure.

Q: Does the complete tape conduct electricity?
A: The carrier can be conductive, but the coating and adhesive affect the complete electrical path. Specify and measure the required finished-tape behavior.

Q: Can it be used as an electrical-insulation tape?
A: Do not assume an insulation rating. The carbon-fiber carrier makes electrical selection different from ordinary nonconductive backing materials.

Q: Can it be used on composite molds?
A: It can be considered as a release cover for compatible tooling and resin systems. Trial the actual cure cycle and required surface finish.

Q: Can seams or fabric texture mark the part?
A: Yes. Evaluate layout and surface texture before production, especially on cosmetic surfaces.

Q: Can it repair a damaged mold?
A: It may provide a replaceable release interface on an otherwise suitable surface. It is not a structural repair or a correction for inaccurate tooling.

Q: Can it operate continuously at 300°C?
A: That capability is not established for this construction. Use the selected model's temperature and exposure-time data.

Q: Can it be supplied with a liner or as die-cut parts?
A: Submit the dimensions, tolerances and handling requirements for the selected converting format.

Q: What else matters for resin processing?
A: Resin chemistry, pressure, dwell time, cleaning, surface impression and downstream painting or bonding all influence selection.
