Carbon & ceramic filled PTFE rod is an advanced engineering grade offering superior wear resistance, improved mechanical strength and excellent dimensional stability, designed for bushings, bearings and CNC-machined components operating under continuous friction and load.
What Is Carbon & Ceramic Filled PTFE Rod?
Carbon & Ceramic Filled PTFE Rod is a high-performance engineering material developed by reinforcing PTFE with a controlled combination of carbon fillers and ceramic particles.
This formulation significantly improves wear resistance, compressive strength and dimensional stability compared to virgin PTFE, making it suitable for demanding industrial applications.
This grade is specifically engineered for environments involving continuous sliding, abrasive contact, mechanical load, elevated temperatures and chemically aggressive media, where standard PTFE grades may suffer from creep or premature wear.
Key Engineering Properties
- Exceptional wear resistance: Designed for severe sliding and abrasive conditions.
- Improved mechanical strength: Better load-bearing capability than virgin PTFE.
- Excellent dimensional stability: Reduced deformation under pressure and heat.
- Wide service temperature range: Suitable for continuous use from approximately -200°C to +250°C.
- Enhanced thermal conductivity: Helps dissipate friction-generated heat.
- Good chemical resistance: Retains most of PTFE’s chemical inertness.
Typical Industrial Applications
- Heavy-duty bushings and bearings operating under high wear
- Wear-resistant CNC-machined components
- Sliding rings and guide elements
- Liners and wear pads in process equipment
- Oil, gas, petrochemical and chemical processing equipment
