PTFE Filler Description
PTFE Filler is made of polytetrafluoroethylene resin by molding. Suspension polymerization PTFE resin is mixed with various fillers to form filled PTFE resin. A variety of fillers suitable for mixing with PTFE include glass fiber, carbon fiber, tin bronze, and lubricants (such as graphite, molybdenum disulfide) and have been widely used in large-scale production. Compared with pure PTFE, filled PTFE has the advantages of higher compressive strength, wear resistance, good heat conduction, and reduced thermal expansion.
