Composition & material selection
Compare filled PTFE compounds for wear, load, creep and thermal behavior. Select the actual filler system and composition rather than a generic filled grade.
Grade characteristics
Use the complete material designation and service conditions when evaluating a compound.
| Material family | PTFE compounded with an identified filler system |
|---|---|
| Selection drivers | Wear, creep, load and heat transfer |
| Compound definition | Filler identity, proportion and any combined additives |
| Interface review | Counterface material, finish and lubrication |
| Compatibility review | Media exposure and electrical requirements |
Filled PTFE is a group of compounds rather than one interchangeable material. Two parts described as filled can have different deformation, friction and electrical behavior.
Keep the filler identity and the supplier grade designation with the drawing. A mixed filler system needs its own data rather than a blend of values taken from separate materials.
A filler selected to improve wear or load response can change other characteristics. Assess media contact, mating-surface wear and electrical duty as part of the same choice.
Use compound data and representative operating conditions when comparing candidates. Test values from different temperatures, loads or sliding arrangements are not direct performance rankings for your assembly.
Specific answers
No. Resin modification and the addition of fillers are different ways of changing material behavior. Identify which material system is specified.
No. Filler type, resin, processing and additional additives also matter. Match the complete compound designation and relevant data.
