Mos2 Filled PTFE
MoS2 Filled PTFE is polytetrafluoroethylene with molybdenum disulfide (MoS2). Adding MoS2 filler makes PTFE material improve various desirable properties such as:
- Wear resistance – you can use the PTFEin high-traffic areas or mating surfaces
- Better compressive strength – it can resist high compressive force before failing
- Self-lubricating – better lubrication properties since it container polar gas
- Even with improved thermal and electrical conductivity molybdenum disulfide-filled PTFE has high dielectric performance
- Improved dimensional stability
- Better creep resistance properties
- Retains better machining properties
At times, you may add other filler materials to MoS2 Filled PTFE. Usually, this improves other functional properties which are not achievable by adding molybdenum disulfide. For example:
- Adding glass or bronze to MoS2 Filled PTFE will make this material smoother, more slippery, and more solid.
- Adding bronze to MoS2 Filled PTFE improves electrical and thermal conductivity
Composition of Filler Material in MoS2 Filled PTFE
The composition of filler material varies depending on the specific performance properties you wish to achieve in molybdenum disulfide-filled PTFE.
| Filler Material by % | Effects of Filler Material in MoS2 Filled PTFE |
| · 55% Bronzer Filler Material
· 5% MoS2 Filler Material |
· Increased creep and wear resistance
· Improved thermal conductivity · Easy to machine · Compromises chemical resistance properties, especially for acidic and alkaline conditions |
| · 5% to 15% MoS2 | · Usually, it is common for MoS2 Filled PTFE without other filler materials |
| · 15% Glass filler
· 5% MoS2 |
· Perfect for making bushings
· More structural strengthening · Reduces possible cold flow |
Applications of MoS2 Filled PTFE
Dynamic sealing systems – it is due to low friction coefficient, high compressive strength, more slippery, and increased wear resistance.
MoS2 PTFE bush bearing – applications involving high speed and mechanical loading due to enhanced mechanical properties
Other applications include cup seals for pistons, bearings, slide covers, and glide rings, amongst others.
