What is PTFE?

PTFE, also known as polytetrafluoroethylene, is a highly fluorinated polymer material renowned for its extremely low coefficient of friction and excellent chemical resistance.

 

It is an ideal solution for applications that require low friction, high service temperatures, and/or strong chemical resistance.

 

This type of plastic is widely recognized under brand names like Teflon®, TECAFLON®, and FLUROSINT®.

Properties and Benefits

 

PTFE is renowned for its excellent sliding properties and extremely low friction, giving it one of the lowest coefficients of friction among materials. This makes PTFE ideal for applications that require smooth surfaces and minimal wear.

 

The material is electrically insulating, has low surface tension, and is highly chemically resistant, especially against acids. It is also UV- and weather-resistant, capable of withstanding high temperatures up to 260°C and low temperatures down to -200°C.

 

However, PTFE has low strength and stiffness and a high expansion coefficient, which can make it soft under pressure. Its strength can be enhanced by adding additives such as glass or carbon.

Is the material approved for food contact?

When you order PTFE components from us, they are FCM-approved as standard, making the material suitable for use in components and machine parts in the food industry.

 

However, this approval no longer applies if a variant with additives is selected.

What is PTFE often used for?

PTFE is commonly used in environments with extreme high or low service temperatures and where chemical resistance is essential. It is also ideal for applications requiring excellent sliding properties. As a result, PTFE is often used for machine parts such as:

 

  • Gaskets
  • Bushings
  • Slide elements
  • Scraper rings
  • Sealing rings
  • Bearings
  • Pump components
  • Tanks
  • Piping systems

Machining of PTFE

The plastic type can be processed using several techniques, which we offer at Induflex. However, the material is best suited for CNC milling or turning.

 

We can CNC turn and mill your plastic components according to your specifications in our state-of-the-art machinery.

Alternative
materials
for PTFE

If PTFE is not the ideal choice for your project, the following plastic types may be good alternatives:

 

  • PEEK: For high-temperature applications that require mechanical properties.

 

  • PVDF: For applications that demand high chemical resistance and good mechanical properties.

 

  • POM: For applications that require high strength and rigidity.

Spørgsmål og svar

  • By sending us a STEP file or PDF with your drawings, we can quickly help determine if PTFE is the right choice for your project.

     

    We can also identify the processing method that best suits the components.

  • At Induflex, we can produce even very tight tolerances in plastic.

     

    When you order a plastic part from us, it will meet Danish Standard ISO 2768-1 (medium) as standard. We measure the tolerances at room temperature, around 21 °C.

     

    Of course, we can agree on different tolerances if you wish.

  • PTFE is an FCM-approved high-performance plastic and can therefore be used for components that come into direct contact with food, such as a machine part for a food processing machine.

     

    However, if additives are used, the FCM approval is void.

  • We have a large inventory of plastics, allowing us to meet requests for standard materials within 14 working days, depending on the complexity of your machine parts.

     

    If your project requires more specialized plastics, such as PTFE with additives, we operate within one month.

     

    We only collaborate with European suppliers, enabling us to quickly order materials to meet your needs.
