Filled PTFE

Filled PTFE is produced by intimately blending virgin PTFE resin with select reinforcements like carbon particles before compression molding and high-temperature sintering, resulting in composites that boost load-handling capacity by 50% over unfilled grades—vital for thrust washers in heavy-duty gearboxes where they prevent galling during oil-starved startups. This filled ptfe variant maintains the base polymer's chemical inertness while adding dimensional stability for repeated autoclave cycles in dental tool holders, avoiding the creep seen in pure sheets under prolonged steam blasts.
