Abrasion and wear of PTFE against metallic partners clearly show improved values even beginning at very low loading of Ceramer or Ceramerplus in PTFE. The coefficient of friction of PTFE (curve c and d) is hardly changed by the addition of Ceramer and Ceramerplus.
The k-factor is a widely used term to describe abrasive properties. It is made up of abrasion in [mm/m] divided by the contact pressure in [N/mm2]. The results (curve a and b) clearly demonstrate the significant reduction of the k-factor even at a low filler content.
