Carbon Filled PTFE Sheet
- Carbon Filled PTFE was developed to provide a PTFE based material with improved mechanical strength.PTFE on its own has excellent frictional properties, elasticity and wear resistance but relatively poor mechanical strength and tends to fail in high PV applications.
- Carbon in itself is a brittle material with poor wear properties and mechanical strength. However with the two combined in Carbon Filled PTFE formulations, the resultant material has excellent mechanical and wear properties, retains the excellent frictional properties and is an excellent choice for seals and rings in dynamic and high pressure applications.Carbon filled PTFE also provides good thermal conductivity, low permeability and is also electrically conductive making it a good choice for anti-static applications.
- The most common carbon filled PTFE composition is 75% Virgin PTFE with 25% Carbon powder by weight.When a filler ratio or type is unspecified, it is fair to assume this is the material. However it doesn t tell the whole story. The type and percentage of carbon added to PTFE is a variable and is critical to material performance.It can be as little as 0.2% and as much as 40%.
- Carbon - Common filled ratio ( Quantity %) 5%, 10%, 15% : Increases compressive strength, hardness, wear, and load properties. Good chemical resistance;Improves electrical properties.
- Carbon Fiber - Common filled ratio ( Quantity %) 10% , 15%, 25%: Increases compressive strength, hardness, wear, and load properties. Reduces creep and cold flow
