and surface smoothness values of TFM PTFE are better than that of PTFE. TFM PTFE components have the same chemical and temperature resistance as PTFE. They can also be welded to one another, or to PFA parts such as tubing to reduce machining waste. Perfluoralkoxy (PFA) is a fully fluorinated polymer...
