PTFE Compounds with Ceramer show improved properties at various sliding speeds and at high and low contact pressure.
The figure on the right clearly shows the improvement of the wear properties of PTFE through the addition of Ceramer at high and low sliding speed.
With 20% Ceramer addition, PTFE can also be used at high surface pressure
(p = 5 N/mm2) and equally at high sliding speeds (v = 4 m/s). Under low stress
(v = 0.5 m/s; p = 1 N/mm2) the addition of 10% Ceramer is sufficient.
