What is PVDF?

PVDF, or polyvinylidene fluoride, is a semi-crystalline thermoplastic with excellent chemical and physical properties.

 

PVDF is commonly used in applications where both high performance and resistance to harsh environments are required.

Properties and Advantages

 

PVDF is resistant to most aggressive chemicals, including acids, bases, and solvents.

 

Additionally, this plastic type has high UV resistance, low moisture absorption, and low permeability to gases and liquids.

 

PVDF also boasts high strength and excellent wear and friction properties, while offering good service temperatures ranging from -40 °C to 150 °C.

 

The material is one of the heavier plastic types, with a density of 1.78 g/cm³. However, PVDF can also cold flow under certain applications, such as extreme high or prolonged loads.

Is the material approved for food contact?

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

 

However, some rods and sheets are not food contact approved. This applies to rods over Ø70 mm and sheets thicker than 50 mm.

What do you use PVDF for?

Due to PVDF's excellent chemical resistance to substances such as alkaline materials, this plastic type is particularly well-suited for environments with stringent cleaning requirements.

 

As a result, PVDF is often used in the pharmaceutical and food industries for applications such as:

 

  • Gaskets
  • Fittings
  • Tanks
  • Valves
  • Pipes

 

And much more.

Machining of PVDF

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

 

At Induflex, we have many years of experience in CNC machining of technical plastics. This means you have a reliable partner for processing your custom plastic components.

At Induflex, we are specialists in plastics. We are ready to help you identify your needs so you can choose the right material for your project. Contact us today for personalized advice on your project.
Spørgsmål og svar

  • 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 components.

     

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

     

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

  • 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.

  • 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 item.
