MATERIAL GUIDE
Filled PTFE
Bronze / Carbon / Graphite
We specialize in PTFE machining — custom CNC machining of filled and unfilled PTFE grades. Bronze, carbon and graphite fillers improve wear resistance, load capacity and dimensional stability while keeping PTFE’s low friction and broad chemical resistance.
Key Properties
Low friction coefficient
Excellent chemical resistance
Wide temperature range
Improved wear resistance with fillers
Non-stick surface
Typical Applications
Bearings and bushings
Wear rings and seals
Valve and pump components
Gaskets and insulators
Food-grade parts (unfilled)
Machining Capabilities
PTFE is machined on CNC mills and lathes to tight tolerances. Filled grades are recommended for load-bearing applications. Prototypes and production runs available.
FAQ：
Q: What fillers are available in PTFE?
A: Bronze, carbon and graphite — each improves wear resistance and load capacity.
Q: Can PTFE be used in food applications?
A: Unfilled PTFE grades can be used in food contact applications. Please confirm your requirements when ordering.
Q: What is the temperature range of PTFE?
A: PTFE operates continuously up to about 260°C (500°F) and performs well at cryogenic temperatures.
