Material Characteristics Of Molybdenum Disulfide Modified PTFE

Using MOS2, glass fiber, A1203, etc. as fillers, PTFE composite sealing ring was prepared. DSH Seals will tell you the influence of PTFE and molybdenum disulfide on the friction performance and wear surface morphology of composite sealing ring. 

Then, what is the influence of the material of the sealing ring modified by polytetraethylene and 

molybdenum disulfide?

Polytetraethylene resin has excellent high and low temperature resistance, chemical corrosion

 resistance, aging resistance, high insulation, non-stick properties, etc., but due to its poor dimensional

 stability, poor thermal conductivity, large creep, low hardness, especially under high load It is easy to 

wear, making it suitable for applications in the fields of mechanical bearing, friction wear and sealing 

lubrication. In order to expand the application field of polytetraethylene sealing ring, we need to 

modify the base filling. That is, the advantages of filling particles such as high hardness, wear

 resistance, dimensional stability, and good thermal conductivity are used to supplement PTFE. 

Commonly used filler particles include glass fiber, carbon fiber, bronze powder, graphite, carbon black 

and some high temperature resistant materials are common composite sealing ring materials.

Molybdenum disulfide modified polytetraethylene seals, let's look at what molybdenum disulfide? 

Molybdenum disulfide is an inorganic compound with diamagnetic properties and semiconductor

 properties. It is a commonly used wear-resistant lubricating filler for high temperature and high

 pressure. It has very good wear resistance, very low friction coefficient and wear resistance. Being used to fill the polytetraethylene resin can improve the anti-wear and anti-wear properties of the composite

 sealing ring material, and prepare high-performance polytetraethylene composite sealing ring

 material. It has a good low anisotropy and low friction coefficient, and has a good bonding effect with

 the polytetrafluoroethylene macromolecular interface, so that the contact area with the substrate is large.
