FKM
FKM Materials for Industrial Seals
Review FKM compounds for a specified fluid and temperature environment. Chemical compatibility, low-temperature behaviour and compression recovery depend on the formulation and application.
01 / FKM
Identify the compound behind the material name
FKM is a material-family designation. Viton™ is a Chemours trademark for fluoroelastomers. Use the manufacturer’s grade documentation to identify a branded reference; specify the proposed compound separately. A brand name in an enquiry does not establish RubberQ authorization, availability of every grade or replacement equivalence.
02 / FKM
Compare complete specifications
Share the existing grade or material callout, the required properties and the actual duty. Polymer grade, cure system and the finished compound all belong in the review. A fluorine-content figure alone is insufficient for approval.
| Input | Details to compare |
|---|---|
| Material reference | Full original grade, compound code, specification and document revision |
| Formulation context | Polymer and cure-system information available for the candidate |
| Media | Complete oil, fuel, chemical or cleaning fluid and its concentration |
| Thermal history | Cold start, normal temperature, peaks, dwell and recovery conditions |
| Seal interface | Drawing, groove, mating surface, compression and motion |
| Evidence | Specimen, preparation, cure or post-cure state, method and acceptance limits |
| Supply | Part or compound form, quantity, lot identification and change requirements |
03 / FKM
Evaluate cold conditions and media together
Define the temperature at startup and during motion, not only the highest operating temperature. Provide a specific fuel, process chemical or lubricant rather than a general fluid category. Compare candidate reports under relevant conditions and identify the assembly checks needed.
- State the sample condition and recovery method for a low-temperature result.
- Record fluid composition, exposure time and measured property changes.
- Verify the required sealing function in the defined assembly.
04 / FKM
Separate material data from part acceptance
A specimen report needs its compound identity, method and preparation. A finished seal also needs dimensional, surface and assembly criteria. Agree which compression or retained-force question matters to the duty, and compare results using the same conditions.
05 / FKM
Prepare the sample and purchasing decision
Send the drawing revision, material reference, quantity and evaluation requirements. For a candidate change, identify the original requirement and approval responsibility before regular supply. Discuss available compound options and required reports against that scope; agree packaging, lot records and change review with the order.
