Question: The mixer operates at a temperature of 180°C, with acetic acid and PX as the working medium, and the pressure is 1.1 MPa. The bearing materials are graphite plus tetrafluoroethylene – is it suitable for use?

Fluororubber cannot be used; EPDM, neoprene/nitrile rubber, and PTFE can be used

Our company has a mixer shaft bearing that is also made of graphite and PTFE; it can operate at a temperature of 152°C, and it has been functioning properly for over a year. I wonder if there are any units that have used it at 180°C?
