PTFE (Teflon) Parts
Polytetrafluoroethylene (PTFE)—also commonly referred to by the brand name Teflon™—is a synthetic polymer material consisting of carbon and fluorine. It has a broad range of beneficial properties that make it suitable for various applications. There are a variety of grades available, each of which exhibits distinct characteristics that suit it for different purposes.
Key Properties of PTFE Plastic
Some of the key properties of PTFE include:
- Melting point: 327° C
- Temperature range: -200° C to 260° C
- Coefficient of friction: 0.05 to 0.10
- Chemical inertness: most chemicals and solvents
- Water absorption: low
- Electrical resistivity: 1.00e+14 – 1.10e+18 ohm-cm
- Dielectric strength: 1.00e+6 – 1.00e+18 ohm
Benefits of Machining PTFE
The above properties make PTFE well-suited for use in a wide array of industrial and commercial applications. For example:
- Its high melting point, flexural strength, and chemical inertness allow it to be used in various harsh operational and environmental conditions. As a result, it is used to manufacture a variety of parts and products for various industries.
- Its low coefficient of friction enables components made from it to experience less wear over time, making it ideal for applications where longevity is critical.
- Its low moisture absorption ensures components made from it maintain the desired dimensions and performance in wet environments.
Types of PTFE
PTFE comes in several variations and grades, each of which can suit different machining and manufacturing needs. These include:
- Virgin Unfilled PTFE. Unfilled PTFE refers to material that does not contain any fillers (e.g., bronze, carbon, glass, etc.).
- Filled PTFE. Filled PTFE contains fillers that improve various aspects of the material, such as stability, creep resistance, and deformation resistance. The exact properties depend on the filler material.
- Food-grade PTFE. Food-grade PTFE complies with FDA standards, making it suitable for use in food and beverage industry applications.

Industries & Applications
Due to its many advantageous properties (e.g., high strength and low coefficient of friction), PTFE finds application in many industries, including, but not limited to, aerospace, cookware, food and beverage, medical, and military. Some of the parts and products typically made from or coated with the material include:
- Bearings and bushings
- Gaskets and seals
- Semiconductor components
- Valve components
- Wear parts
