Carbon and ceramic filled PTFE sheets engineered for high wear resistance, improved mechanical strength, dimensional stability and reliable performance in demanding industrial environments.
What is Carbon + Ceramic Filled PTFE Sheet?
Carbon + Ceramic Filled PTFE Sheet is an engineered PTFE grade reinforced with a balanced blend of
carbon fillers and ceramic particles to improve wear resistance, load performance, and
dimensional stability compared with virgin PTFE. It is designed for applications where
continuous sliding contact, higher pressure, elevated temperature, and chemical exposure must be handled reliably.
Engineering Advantages
- Very high wear resistance: excellent for sliding and abrasive service conditions.
- Improved load capacity: higher compressive strength versus standard PTFE.
- Superior dimensional stability: reduced deformation under pressure and temperature cycles.
- Lower creep (cold flow): better long-term sealing and shape retention.
- Low friction performance: smoother motion and reduced counter-surface wear.
- Improved heat dissipation: better thermal conductivity than virgin PTFE.
- Good chemical resistance: compatible with many industrial fluids and process media.
Common Industrial Applications
- CNC-machined wear parts for continuous sliding contact
- Heavy-duty bushings & bearings under load and friction
- Industrial liners & slide plates in abrasive or high-cycle equipment
- Wear rings, guide rings & support rings
- Sealing components in valves, pumps, and rotating equipment
- Oil, gas, petrochemical & process equipment

FAQ – Carbon + Ceramic Filled PTFE Sheet
1) How is carbon + ceramic filled PTFE different from virgin PTFE?
It offers significantly higher wear resistance, better compressive strength, and improved dimensional stability,
while maintaining PTFE’s low-friction behavior for sliding applications.
2) Is this sheet suitable for bearings, bushings, and heavy sliding parts?
Yes. This grade is commonly selected for heavy-duty bushings, bearings, liners, and CNC wear parts where load,
friction, and long service life are critical.
3) Does it maintain chemical resistance like PTFE?
It retains good chemical resistance for many industrial media. For extremely aggressive chemical environments,
material selection should be verified based on the specific fluid and temperature.
