Teflon® is a soft, low friction material that sees extensive use across a range of applications due to its resistant and insulating properties. As a leading manufacturer of high-performance plastics, COMCO Plastics can deliver a range of high-quality, precision Teflon® components to meet various industry needs.
What is PTFE/Teflon®?
Polytetrafluoroethylene (PTFE), or Teflon® as it is commonly known, is a synthetic tetrafluoroethylene fluoropolymer. Depending on the needs of a particular application, the mechanical properties of PTFE, such as creep and wear rate, can be improved with the addition of fillers. Ideal fillers include graphite, carbon fiber, carbon, steel, bronze, and glass fiber.
The specific properties of PTFE include:
- Low water absorption
- Availability of high-purity grades for food and medical applications
- Good fatigue resistance under low stress
- Highly flexible
- Strong anti-adhesion properties
- Low dielectric constant and dissipation factor
- Low coefficient of friction
- Good resistance to weathering, UV, and light
- Good electrical insulation properties in hot and wet environments
- Good heat and low-temperature resistance
- Exceptional resistance to chemicals
- PTFE/Teflon® Applications
Various applications rely on PTFE, including:
- Automotive: Power steering, transmission, fuel hose linings, shaft seals, valve stem seals, gaskets, and O-rings
- Chemical Industry: Containers, autoclaves, reaction vessels, tanks, impellers, diaphragms, pumps, and heat exchanger coatings
- Electrical and Electronics: Semiconductor parts, flexible printed circuit boards, electrical insulation
- Engineering: Pump and valve parts, fittings, pipe coatings, non-stick surfaces, bearings, seals, and plugs
- Medical: Heart patches, ligament replacement, and cardiovascular grafts
PTFE/Teflon® Machining Considerations
When machining Teflon®, it is vital to consider its characteristics to ensure you deliver the desired results. For example, consider the following:
- PTFE has a density and softness that makes it easy to machine
- PTFE has an extensive temperature range from -450 °F to more than 500 °F (-267.7 °C to +260 °C)
- Teflon®‘s strength is low compared to nylon
- Tight tolerances can be difficult to achieve due to PTFE’s sensitivity to stress creep and a high coefficient of expansion
- Joining PTFE can be difficult
- PTFE may release toxic fumes and has corrosive properties
- PTFE has a low resistance to radiation
