What is PTFE and Why It Matters in Engineering

The PTFE is a fluoropolymer with outstanding chemical inertness and thermal resistance. It has many applications in areas where other plastics break down rapidly. PTFE has a very low coefficient of friction which makes it suitable for use in sliding and sealing applications.

PTFE is useful in engineering systems as it will not react with acids, bases or solvents. It also has a good performance in extreme low or high temperatures. This allows it to be used in a variety of applications, including chemical processing, pharmaceuticals, automotive and aerospace.

Various industries have come to depend on machined ptfe parts to obtain precision performance from their seals, bushings and insulation parts. These parts will be used in extreme environments, where conventional materials cannot be used.

Overview of PTFE Machining Processes

PTFE machining involves the cutting, shaping and finishing of raw PTFE stock into functional components, and is a specialized process. While PTFE is soft and flexible, unlike metals it is not easy to machine without deforming it.

The common methods used in CNC are turning, milling, drilling and precision finishing. The most important consideration is temperature control or tool sharpness and getting the correct results.

In high volume manufacturing situations, engineers would often rather have cnc machined ptfe parts because of its dimensional accuracy and repeatability.
