カーボン充填PTFE
If you are looking for polytetrafluoroethylene with improved thermal conductivity, then PTFE with carbon filler is a perfect option. The carbon fillers are responsible for the PTFE素材’s static dissipative property.
Like other polytetrafluoroethylene materials, you can find many forms such as carbon-filled PTFE rods, carbon-filled PTFE sheets, carbon-filled PTFE tubes, etc.
Like other fillers, carbon-filled PTFE exhibit improved performance characteristics such as:
- Improved resistance to deformation even under heavy load
- Exhibits improved compressive strength
- Better resistance to wear
- It exhibits low permeability
- Improved thermal conductivity due to carbon fillers
- Better extrusion resistance
Your Professional Carbon-Filled PTFE Manufacturer
Compared to glass-filled polytetrafluoroethylene, carbon-filled PTFE is less abrasive. Again, it is worth noting that carbon-filled PTFE performs better in strong bases and HF, with a low coefficient of friction.
At the same time, carbon fillers lower PTFE creep properties. However, the carbon-filled PTFE temperature range is -200°C o +260°C.
In most cases, carbon fillers in PTFE can range from 0.2% to 40%. The amount of carbon fillers by weight (%) will depend on the specific performance properties you want to achieve.
Applications of Carbon-Filled PTFE
Seals and rings – suitable for high-pressure and dynamic applications
Anti-static applications – this is due to low permeability and improved thermal conductivity
Carbon-filled PTFE brushing – due to its hardness and wear resistance
At times, you may add other fillers to carbon-filled Teflon for enhanced performance. Some common PTFE fillers are 3% graphite and 10% glass.
