PTFE extrusion process with a PTFE extruder, which is also referred to as a PTFE paste extruder or only as a PTFE extruder

Paste extrusion is used in the PTFE production of thin tubes, thick tubes, wire insulations and unsintered PTFE tapes. For the PTFE paste extruder, only emulsion polymerization powder is used. The paste is a mixture of these spongy PTFE powder types with moistened organic liquids.
