60% Bronze Filled PTFE Rod Bronze Filled PTFE Tube Bronze PTFE Sheet
PTFE Bronze Filled is the most common metal filler and it is dark brown in color. Bronze filler has excellent wear, creep resistance, and higher
thermal conductivity that glass fiber with PTFE. Adding bronze in percentages 60% can increase wear PTFE resistance. PTFE Bronze-filled has
poor chemical resistance in the presence of acids and alkali. PTFE Bronze-Filled is machined and used in bearings at high speeds when shafts
are not hardened. It is useful in applications with higher mechanical loads and higher speeds rubbing contact points where bronze-filled supplies
the strength and conductivity to carry away excess and unwanted heat. Used in hydraulic systems, superb for linear bearing, slides, guide ways,
bearing rings, piston rings and wear pads., etc
