Background
Polytetrafluoroethylene (ptfe) is a molten but non-flowable material that cannot be extruded through an extruder (conventionally called hot extrusion) as thermoplastics (e.g., polyethylene, polyvinyl chloride) during the insulation process of electrical wires using ptfe, but can only be extruded by what is commonly known as cold extrusion.
