PTFE Bronze-Filled


B.I.R.S. Machine & Supply distributor of PTFE (Teflon®) Bronze-Filled sheet, rod,

tube, cylinders, bushings, plate, wear strips & machined components. PTFE

Bronze-Filled is available in 40 percent or 60 percent filler and 55% Bronze / 5%

Moly-Filled PTFE 


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

than glass fiber with PTFE. Adding bronze in percentages of weigh between 40%

and 60% can increase wear.  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 the bronze-filled supplies the strength and conductivity to carry away excess and unwanted heat. Used in hydraulic systems, superb for linear bearings, slides, guide ways, bearing rings, piston rings and wear pads in Alabama, Georgia, Mississippi, Louisiana, Texas and the rest of the industrial world. 


Not suited for electrical applications.

Certain chemicals attack bronze.
