PTFE compounds are based on the dry blend of fine-cut granular PTFE powder and a series of fillers, which can be used to produce products for low friction applications. On the premise of retaining the unique characteristics of PTFE, adding different fillers to PTFE will have varying degrees of impact on the wear resistance, creep resistance, thermal conductivity and electrical conductivity of PTFE.
|Type||Effects of Filler||Use restriction||Application|
|Filled with glass fiber||Resistant to organic solvents, not resistant to alkaline solutions and acids||Valve seats, seals, bearings, requested to resist sliding and chemicals. Suitable for bearings working at low pH values.|
|Filled with carbon fiber||Carbon fiber is chemically inert||Plain bearings, sealing rings, moving parts operating under conditions of limited lubrication or without lubricants.|
|Filled with graphite||When used with hard metals, it has high wear resistance and is easy to oxidize||Bearings for high speed on fairly hard surface.|
|Filled with molybdenum disulfide (MoS2)||Not resistant to corrosion when used with hot concentrated sulfuric acid||Seals and bearings with high elasticity and lowest friction coefficient. Guide bands. Details needing good resistivity.|
|Filled with bronze||May be corroded by acid and water||Unlubricated bearings for high speed on moderately hard surface.|
