Graphite filled PTFE rod combines the lubricity of PTFE with the wear-control properties of graphite, forming a stable graphite round bar that resists friction, deformation, and heat in high-load sliding systems.

Graphite filled PTFE rod is an extruded composite built from PTFE blended with finely distributed graphite particles, forming a dense graphite round bar that delivers significantly improved wear resistance compared with unfilled PTFE. The presence of graphite lowers the dynamic friction coefficient, allowing the material to operate smoothly under higher surface pressures and elevated temperatures without surface scoring or rapid deformation. During extrusion, the mixture forms a uniform microstructure that maintains lubrication even when subjected to repeated sliding cycles or oscillating movement. This composition makes the rod suitable for components that must run dry, manage intermittent lubrication, or resist stick-slip behavior. Thermal stability remains consistent up to approximately 260°C, and the graphite phase enhances heat dissipation around contact surfaces, reducing localized temperature spikes common in valve stems, guide rings, and reciprocating seals.
The rod machines cleanly into bushings, seal rings, wear plates, spacers, thrust washers, and low-friction support elements. Its controlled compressive creep lends the material reliable behavior under long-term loading, particularly in pumps, industrial mixers, hydraulic equipment, and rotating machinery where pure PTFE would soften or cold-flow excessively. Chemical resistance remains broad, with graphite contributing no reactivity, allowing the material to function in corrosive chemicals, process fluids, and abrasive media.
