Ekonol T101 aromatic polyester filler is a tan powder additive that, when combined with PTFE, produces a composite material with excellent temperature and wear resistance for a wide range of mating surfaces in demanding services. This filler extends the life of bearings and other large moving parts that may contain silica or alumina.

The highly crystalline structure of the Ekonol T101 polymer was created to deliver maximum dimensional, chemical & thermal stability. In addition, the non-abrasive character of Ekonol T101 polyester enhances the frictional performance to prevent galling of softer mating surfaces better than other PTFE fillers.
