Filled graphite carbon copper PTFE tube

Filled Graphite / Carbon / Copper filled PTFE tube is a high-performance fluoropolymer composite tube manufactured by blending selected conductive and wear-resistant fillers into PTFE resin, followed by room-temperature compression forming and controlled sintering. The fillers are uniformly dispersed within the PTFE matrix, forming a reinforced structure designed to withstand demanding mechanical and thermal operating environments.

Each filler contributes distinct functional benefits:

1. 1. Graphite improves dry-running performance and stabilizes friction behavior at elevated temperatures.
2. 2. Carbon increases wear resistance, surface hardness, and dimensional stability while maintaining chemical compatibility.
3. 3. Copper enhances thermal conductivity and load-bearing capability, particularly in applications where heat accumulation must be controlled.
4. 4. The combination or individual selection of these fillers can be adjusted to match specific operational requirements.

Performance Characteristics

• Improved compressive strength compared with unfilled PTFE
• Lower deformation under long-term mechanical stress
• Enhanced resistance to abrasive wear
• Better thermal dissipation in rotating or sliding assemblies
• Stable friction behavior across varying speeds and temperatures
• Maintains chemical inertness in most industrial media

Filled Graphite / Carbon / Copper filled ptfe tube is widely used in:

• High-load bushings and bearing sleeves
• Hydraulic and pneumatic sealing systems
• Compressor and pump wear components
• Rotating shaft guides and support rings
• Equipment exposed to combined mechanical stress and elevated temperature

Customization & Machining

Available in various inner and outer diameters with customizable filler types and concentration ratios. Filled PTFE tube can be further machined into precision components according to engineering drawings, ensuring dimensional accuracy and application-specific performance optimization.
