Glass Fiber Reinforced PTFE Rod

Chunhuan’s glass fiber filled PTFE rods and sheets are designed for applications demanding high wear resistance, dimensional stability, and low friction. By integrating 15%-40% glass fiber into a PTFE matrix, this composite material significantly enhances mechanical properties while maintaining PTFE’s hallmark chemical inertness and wide thermal stability.

Key Advantages:

• Superior Wear Resistance

  • Up to 8-12× improvement over virgin PTFE

  • ASTM D3702 tested: 20% GF variant shows only 9% wear compared to pure PTFE

• High Load-Bearing Capability

  • Static pressure resistance: up to 140 MPa (ISO 604)

  • Dynamic applications: ≤35 MPa

• Excellent Anti-Creep & Dimensional Stability

  • 5× improved performance in long-term compression and deformation

• Enhanced Self-Lubrication

  • Dynamic friction coefficient: 0.12 ± 0.03, ideal for dry-running seals

• Chemical Resistance & FDA Compliance

  • Resistant to acids, alkalis, solvents

  • FDA 21 CFR 177.1550 certified for food and pharmaceutical use

Available Forms:

• Rod / Sheet / Bushing / Custom CNC Parts

• Standard Grades:

  • 15% GF (general use)

  • 25% GF (military-grade)

  • 40% GF (heavy-duty)

Applications:

• High-pressure valve seats

• FDA-approved bushings for food machinery

• Anti-creep gaskets and piston rings

• Low-friction bearings for pharmaceutical and chemical pumps

Testing & Documentation Support:

• ASTM D2990 creep curves

• Chemical resistance charts

• Third-party wear resistance reports
