PTFE Carbon-Graphite Tube

Carbon-Graphite Filled PTFE Tubes (Guarniflon Italy)

High-Performance Self-Lubricating Fluoropolymer Sleeves

If your engineering application demands a material that surpasses the mechanical limits of virgin PTFE, Carbon-Graphite filled PTFE tubes offer the ideal balance of wear resistance, thermal conductivity, and load-bearing capacity.

We proudly import and distribute genuine, high-grade Carbon-Graphite PTFE hollow rods and tubes manufactured by Guarniflon Italy—a global benchmark in fluoropolymer excellence. Engineered for punishing industrial environments, this composite material integrates the low-friction characteristics of polytetrafluoroethylene (PTFE) with the structural reinforcement of carbon and graphite particles.

Why Choose Carbon-Graphite Filled PTFE?

While virgin PTFE is renowned for its chemical inertness, it can exhibit material deformation (creep) under heavy mechanical loads. By compounding the matrix with a precise blend of carbon and graphite fibers, Guarniflon significantly enhances the physical properties of the compound:

• Minimized Material Creep & Cold Flow: The carbon reinforcement dramatically increases initial deformation resistance, allowing machined parts to maintain structural integrity under continuous load.
• Enhanced Thermal and Electrical Conductivity: Graphite flakes create a conductive network within the polymer matrix, efficiently dissipating heat from friction and preventing static electricity buildup.
• Optimized Wear Resistance: The self-lubricating synergy between the PTFE base and the graphite filler yields exceptional dry-running properties, significantly extending the lifespan of dynamic components.
• Excellent Chemical Compatibility: It retains the vast majority of PTFE’s chemical resistance, making it suitable for corrosive environments, fluids, and harsh industrial solvents.

Technical Specifications and Material Properties

As an authorized supplier of Guarniflon Italian compounds, we ensure our semi-finished tubes meet stringent international quality standards.

Key Material Attributes:

• Filler Composition: Premium Carbon and Graphite blend optimized for dynamic friction.
• Service Temperature Range: Functional from $-200^\circ\text{C}$ up to $+260^\circ\text{C}$.
• Friction Coefficient: Low dynamic coefficient of friction, ideal for unlubricated setups.
• Suitability: Outstanding performance in water, steam, hydraulic oils, and chemical processing media.

Primary Industrial Applications

Thanks to their high dimensional stability and superior wear performance, these premium Italian-imported tubes are custom-machined into vital industrial components across various sectors:

1. Fluid Handling & Hydraulics

Perfect for manufacturing high-durability hydraulic seals, piston rings, rider rings, and rod packings where traditional lubricants cannot be used or might contaminate the process fluid.

2. Chemical Processing & Petrochemicals

Used for valve seats, gaskets, and mechanical seal faces that handle aggressive acids, alkalis, and high-pressure steam.

3. Automotive & Heavy Machinery

Ideal for self-lubricating bushings, sleeve bearings, and thrust washers subjected to high velocity and heavy mechanical loads.

Secure Premium Guarniflon Italian Quality

When it comes to high-stakes engineering components, material consistency is non-negotiable. Substandard filler distribution or poor compounding can lead to premature component failure.
