10% PEEK-filled PTFE bushings combine the best properties of PTFE and PEEK, resulting in a high-performance material ideal for demanding applications. These bushing ptfe components offer high modulus, excellent temperature resistance, and low friction while maintaining FDA compliance for use in sensitive environments like food production and medical applications. Their unique blend of 90% virgin PTFE and 10% PEEK creates a cream-colored material with 60 Shore D hardness that outperforms pure PTFE in high-load scenarios.
Key Points Explained:
-
Material Composition
- 90% virgin PTFE provides the base material's excellent chemical resistance and low friction properties
- 10% PEEK reinforcement significantly improves mechanical strength and temperature resistance
- The combination creates a synergistic effect where PEEK enhances PTFE's structural properties without sacrificing its beneficial characteristics
-
Physical Properties
- Color: Distinctive cream appearance (unlike pure white PTFE)
- Hardness: 60 Shore D (substantially harder than unfilled PTFE)
- Density: Higher than pure PTFE due to PEEK reinforcement
- Flexibility: Maintains some flexibility despite increased stiffness
-
Performance Characteristics
- High modulus: Can withstand greater loads than standard PTFE bushings
- Temperature resistance: Performs well in both high and low temperature environments
- Low friction: Maintains PTFE's self-lubricating properties (coefficient of friction ~0.1)
- Chemical resistance: Inherits PTFE's near-universal chemical inertness
-
Special Features
- FDA-CFR 21 compliant: Safe for food contact and medical applications
- Quiet operation: Ideal for noise-sensitive environments
- Low maintenance: Self-lubricating properties reduce servicing needs
- Back-up ring suitability: Excellent for high-pressure sealing applications
-
Comparison with Pure PTFE Bushings
- Superior mechanical strength and load capacity
- Better dimensional stability under stress
- Higher temperature threshold (PEEK raises continuous service temperature)
- Slightly reduced chemical resistance compared to pure PTFE
- Less flexible but more durable in high-wear applications
-
Typical Applications
- High-performance seals and bearings in chemical processing
- Food processing equipment components
- Medical device components requiring FDA compliance
- Aerospace and automotive applications needing temperature resistance
- Industrial machinery requiring low maintenance solutions
The 10% PEEK filling transforms standard PTFE into a more robust engineering material while preserving most of PTFE's beneficial properties. This makes these bushings particularly valuable in applications where pure PTFE would deform or fail under mechanical stress, but where PTFE's unique characteristics are still required.
