Glass fiber for strength alone. Carbon fiber for strength + thermal conductivity + static dissipation. Choose by application, not by cost. Request a quote in 24 hours, send your size, specification, and application.

What Is Carbon Fiber-Filled PTFE Tube?

Carbon fiber-filled PTFE tube is manufactured by adding 15-35% carbon fiber filler to PTFE resin through compounding, then extruding or molding into tube form.

Carbon fibers provide a reinforcing network that dramatically improves mechanical properties while making the material thermally and electrically conductive.

Why Conductivity Matters

In many industrial applications, PTFE components are used in environments where static electricity can cause serious problems:

Virgin PTFE is a perfect electrical insulator (volume resistivity >10¹⁸ Ω·cm), it cannot dissipate static charge.

Carbon fiber-filled PTFE reduces resistivity to 10⁴-10⁶ Ω·cm, providing a safe path for static electricity to flow to ground.

What this means for you: If you are currently using virgin PTFE tubes in applications where static discharge is a concern, carbon fiber filled PTFE eliminates the static risk while maintaining chemical resistance and low friction.

Why Choose Carbon Fiber-Filled PTFE Tube?

1. High Mechanical Strength

Carbon fiber reinforcement provides tensile strength up to 40 MPa, significantly higher than virgin PTFE. Handles higher loads, pressures, and mechanical stress without deformation.

2. Better Thermal Conductivity

Carbon fiber network efficiently dissipates frictional heat, 3-5x better than virgin PTFE. Prevents heat buildup that can cause seal damage, shaft scoring, or premature failure in high-speed dynamic applications.

3. Electrical Conductivity

Volume resistivity of 10⁴-10⁶ Ω·cm makes the tube conductive. Prevents electrostatic discharge (ESD) that can damage sensitive electronics, ignite flammable materials, or attract contamination in cleanroom environments.

4. Anti-Static / Static Dissipative

Safely dissipates static charge to ground. Meets static control requirements in semiconductor, chemical, and pharmaceutical manufacturing. Reduces product contamination from static-attracted particles.

5. Reduced Creep and Cold Flow

Deformation under load ≤8%, maintains dimensional stability over time. Carbon fiber reinforcement prevents the cold flow deformation that causes virgin PTFE components to fail under sustained load.

6. Wear Resistance

Carbon fibers create a low-friction, wear-resistant surface that extends component life in sliding and dynamic applications. Outperforms virgin PTFE and graphite-filled PTFE in abrasive conditions.

7. Universal Chemical Resistance

Retains PTFE's pH 0-14 chemical resistance, compatible with most acids, alkalis, solvents, and aggressive media.

⚠️ Not compatible with strong oxidizers (carbon can oxidize).

FAQ

Q: Carbon fiber-filled PTFE tube and glass fiber-filled PTFE tube, which one should I choose?

A: Both offer improved mechanical strength, but carbon fiber has two critical advantages over glass fiber:

(1) Thermal conductivity: carbon fiber dissipates frictional heat 3-5x better than glass fiber, preventing heat buildup in high-speed applications.

(2) Electrical conductivity: carbon fiber provides static dissipation (10⁴-10⁶ Ω·cm), preventing ESD damage in sensitive environments. Glass fiber remains an electrical insulator.

Choose carbon fiber for: High speed, heat dissipation, static-sensitive applications.

Choose glass fiber for: Abrasive media, high wear, general chemical service where static is not a concern.

The same chemical resistance applies to both (pH 0-14), but carbon fiber is black and more expensive.

Q: Is carbon fiber-filled PTFE tube conductive enough for ESD applications?

A: Yes. Carbon fiber-filled PTFE tubes have a volume resistivity of 10⁴-10⁶ Ω·cm, which falls within the static dissipative range (typically 10⁴-10¹¹ Ω·cm).

This provides a safe path for static charge to drain to ground, making them suitable for ESD-sensitive environments like semiconductor manufacturing, cleanrooms, and flammable fluid handling. Virgin PTFE is an insulator (>10¹⁸ Ω·cm) and cannot dissipate static charge.

Q: What are the temperature and pressure limits for carbon fiber-filled PTFE tube?

A: Temperature: Continuous -180°C to +200°C.

Pressure: Carbon fiber filled tubes handle higher pressures than virgin PTFE due to improved mechanical strength, up to 8.0 MPa depending on tube design and wall thickness.

Chemical: pH 0-14, resists most acids, alkalis, and solvents.

⚠️ NOT compatible with strong oxidizers at high temperatures (carbon can oxidize), e.g., nitric acid, chlorine.
