Composition & material selection
Carbon-filled PTFE compounds for sliding and seal components. Identify the carbon form, any graphite blend and the required electrical behavior.
Grade characteristics
Use the complete material designation and service conditions when evaluating a compound.
| Filler identity | Carbon powder, carbon fiber or a defined blend |
|---|---|
| Selection duties | Moving seals, sliding components and wear interfaces |
| Compound inputs | Resin, filler proportion and additional additives |
| Electrical requirement | Measured resistance for the intended duty |
| Service data | Media, lubrication, load and motion |
Carbon-filled is not a complete compound designation. Powder, fiber and carbon-graphite mixtures differ, so the supplied material must be identified before comparing performance.
For moving seals and sliding parts, define the contact motion and lubrication. A property improvement in one test arrangement does not establish an identical result in another machine.
Carbon additions can change electrical conductivity. If the part must dissipate charge or remain insulating, state the resistance requirement and test conditions.
Black color does not prove a carbon formulation or a static-control rating. Pigmented PTFE and carbon compounds need separate identification and documentation.
Specific answers
No. A black appearance can come from pigment or different filler systems. Identify the compound rather than using color as a material specification.
No. Specify the resistance range and test method required by the application; the filler name alone is insufficient.
Select by composition
Send the compound designation, motion and lubrication details, contact media and drawing. Include resistance requirements if static control is part of the duty.
