The temperature resistance of PTFE/- Ceramer compounds was measured in tests with the sliding surface temperature above of 23 ºC. At temperatures over
150 ºC, unfilled PTFE flows under stress.
Through the addition of small amounts of Ceramer, the temperature can be raised to over 200 ºC.
The maximum temperatures at which PTFE/Ceramer compounds can be used lies at between 220 ºC and 260 ºC, depending on the Ceramer content. In this temperature range, the Ceramer content should be at least 10% to 20%.
