What are the differences between fluorine rubber gasket and PTFE gasket?
The main difference: the ductility and mechanical properties. Both of them belong to the thermosetting resin, high temperature can be more than 200℃. But PTFE reached 260℃ began to decompose. Fluorine rubber depends on the specific species. Specific mechanical properties can be done tensile test.
The same material, different shapes of PTFE products, physical properties and chemical properties are somewhat different.
