Composition & material selection
Graphite-filled PTFE for sliding interfaces and seal components. Select the formulation with the counterface, lubrication and contamination limits in view.
Grade characteristics
Use the complete material designation and service conditions when evaluating a compound.
| Filler system | Graphite alone or identified combined fillers |
|---|---|
| Selection priority | Friction and wear at the contact interface |
| Use context | Sliding parts, rings and seal components |
| Mating surface | Material, finish and lubrication condition |
| Process requirement | Electrical and cleanliness limits where applicable |
Graphite-containing compounds are considered for sliding duties where the contact surface and lubrication affect friction and wear. Their behavior still depends on load and speed.
A soft mating surface needs a different review from a hard shaft. Provide the counterface material and finish rather than selecting only from a nominal friction description.
Graphite often appears in mixed compounds. A carbon-graphite or glass-graphite formulation should retain its full designation so it is not confused with graphite-only PTFE.
Where cleanliness or electrical behavior matters, request the relevant grade data. Neither appearance nor a self-lubricating description establishes suitability for every process.
Specific answers
No. The actual load, speed and counterface determine the sliding condition, including whether dry operation is suitable.
No. The names describe different filler choices or blends. Match the complete formulation when replacing a part.
Select by composition
Provide the formulation, counterface material and finish, speed, load and lubrication. Add cleanliness and electrical requirements with the component drawing.
