Bronze-filled PTFE combines the excellent non-stick and chemical-resistant properties of PTFE with the mechanical toughness of bronze powder, making it ideal for high-pressure seals, guide strips, slideways, and bushings.
A bronze filled PTFE strip is a flat, precision-cut strip made from PTFE resin blended with 40% (or custom %) bronze powder. The inclusion of bronze significantly enhances the compressive strength, thermal conductivity, and wear performance of PTFE while retaining its low-friction, self-lubricating surface.
These strips are ideal for sliding surfaces, dynamic seals, and wear plates that must handle repetitive motion, higher loads, or elevated temperatures.
- Enhanced wear resistance: Up to 5x more durable than virgin PTFE
- Higher load-bearing capacity: Suitable for structural and dynamic loads
- Improved thermal conductivity: Reduces heat buildup during movement
- Low friction surface: Minimizes energy loss and prevents stick-slip
- Dimensional stability: Less creep and deformation under pressure
- Customizable strip dimensions
- Operates under continuous pressure, load, and motion
- Ideal for both dry and lubricated service conditions
- Maintains sealing integrity under temperature fluctuations
- Excellent replacement for metal-backed wear strips
- Reduces maintenance downtime in high-speed machinery
