Can rubber gaskets replace PTFE gaskets? What are the temperature, pressure, and solvent resistance properties of rubber?
Looking at the properties of the materials, rubber has lower corrosion resistance compared to PTFE
It mainly depends on the operating conditions, such as the medium, temperature, corrosivity, pressure, and so on
It’s not necessarily possible; requirements vary in different places
No, there are differences in temperature, pressure, etc
In many cases it’s not possible; factors such as the operating environment, pH level, temperature tolerance, and chemical properties play a role – materials like DMF, ethyl ester, concentrated sulfuric acid, etc., still require tetrafluoro gaskets.
