Filled PTFE
2025年5月21日Revolutionizing Performance: 90% Virgin PTFE with 10% Glass Fiber Reinforcement
In the world of advanced engineering materials, filled PTFE compounds have emerged as game-changers for demanding applications. Among these, the glass fiber filled PTFE composition featuring 90% virgin PTFE and 10%±1% glass fibers stands out as a particularly exceptional material solution. This precise formulation represents the perfect balance between PTFE’s inherent beneficial properties and enhanced mechanical characteristics.
What Makes This PTFE Composition Special?
Pure PTFE (Polytetrafluoroethylene) is renowned for its outstanding chemical resistance, low friction coefficient, and excellent electrical insulation properties. However, its limitations in wear resistance, creep resistance, and mechanical strength have driven the development of reinforced compounds. The addition of precisely 10% glass fibers transforms the material while maintaining the core benefits that make PTFE so valuable.
Key Advantages of 90/10 Glass Fiber Filled PTFE:
- Enhanced Wear Resistance: 3-5x improvement over virgin PTFE
- Superior Compression Strength: Withstands higher loads with minimal deformation
- Improved Creep Resistance: Maintains dimensional stability under continuous load
- Excellent Thermal Stability: Performs consistently from -200°C to +260°C
- Maintained Chemical Inertness: Resists virtually all industrial chemicals
- Low Friction Coefficient: Remains an outstanding bearing material
