Composition & material selection
Bronze-filled PTFE for loaded wear and sealing components. Evaluate the metallic filler against the fluid, counterface and electrical requirements.
Grade characteristics
Use the complete material designation and service conditions when evaluating a compound.
| Filler | Identified bronze composition and proportion |
|---|---|
| Selection focus | Loaded contact and deformation control |
| Part contexts | Guide components and hydraulic sealing profiles |
| Media review | Compatibility with the metallic filler |
| Electrical consideration | Metal-filled compound assessed separately from virgin PTFE |
Bronze-filled compounds are candidates for parts that need a different load response from unfilled PTFE. The exact formulation and mating surface determine the useful operating range.
For a seal or guide, include pressure, extrusion clearance and movement. Those inputs determine whether the compound and geometry work together in the housing.
The PTFE matrix does not remove the chemical characteristics of bronze. Process media and cleaning agents must be assessed against the complete compound.
Metal additions also change heat transfer and electrical behavior. An insulating part cannot inherit virgin PTFE electrical assumptions after bronze is introduced.
Specific answers
No. The metallic filler can limit compatibility. Review the actual chemical and conditions against the supplied compound.
No. It is a PTFE-matrix compound with bronze filler. A metal bearing has a different structure and specification.
Select by composition
Provide the specified grade, load, movement, media and temperature with the part drawing. Include any electrical-isolation requirement.
