PVDF what is the complete information

PVDF is among the most important and advanced plastic materials available today to those who produce in plastic. In the field of plastic, there is always the dilemma of which material to choose? Therefore it is important to know the different materials and understand which of their structures is the most suitable and when? So what is PVDF? What are its advantages? And where and when should you use it? is all that is important to know.

What is PVDF?

PVDF, or polyvinylidene fluoride, is one of the names you will surely hear if you are interested in manufacturing in the field of plastics. It is artificially produced and designed with different features depending on the need. It also has its own special variations, such as Copolymers of PVDF or Terpolymers of PVDF. For the sake of clarification, it is important to know that PVDF is not PVF (polyvinyl fluoride) nor is it PVC (polyvinyl chloride), but a different material.

What is PVDF used for?

Today there are quite a few types of plastic that I can choose from in different production processes, depending on the industries and intended uses. PVDF is widely used in many industries, such as the world of electronics. Its uses are also diverse, including piping for transferring different liquids or tubes that shrink in heat. In light of its special properties, it is also considered to be very suitable where a lot of cleanliness is required, for example in the pharmaceutical industry or electronics production. This is also seen in food production processes, such as the transfer of wine in the production pipeline. It can also be processed by the method of plastic welding (“plastic soldering”). This point makes it very suitable in cases where it is necessary to connect parts that will be as strong as possible and also aesthetic. Of course, the combination of its special features is what often leads to choosing it. For example, for the production of a coating for electric conductors, combining its ability to be insulated, the fact that it is lightweight and flexible. Also, the electric current in the wires and their operating environment create heat which PVDF is resistant to.

PVDF material properties

  • Thermoplastic – pvdf is a thermoplastic material. Thanks to this, it can be used as part of the plastic injection process by heating it and injecting it into molds.
  • Has excellent chemical resistance – this material is resistant to other harsh substances of many types. Therefore it can be used where it is necessary to store such materials or transfer them as a liquid in pipelines.
  • Has resistance to the sun – therefore suitable for applications that will be exposed to intense sun and for a long time.
  • Resistant to microorganisms – PVDF is an uncomfortable material in terms of creatures such as bacteria as an area for their growth, thanks to this the piping remains extremely clean and protected.
  • Piezoelectric – the material creates an electric voltage when physical pressure is applied to it. This feature is used, among other things, in the production of various sensors.
  • Resistance to radiation – a surprising and interesting aspect is that this material is also very resistant to nuclear radiation!

What is the difference between PVDF and PVC?

Polyvinyl chloride (PVC) is produced through the polymerization of vinyl chloride monomer. It is a very common material in the field of plastics while PVDF is used to a lesser extent. The two materials are somewhat similar in composition and use, but in practice there are also many significant differences between them. Among other things, PVDF is a stronger material both against chemical substances and in terms of the strength of its structure.

Common questions

Which is better PVDF or PVC?

The answer to this question depends on the purpose of use. PVC will be suitable for many purposes, but PVDF may have different advantages over it, in specific cases and depending on the circumstances. For example, where resistance to high temperatures is required, PVDF is preferable.

What is PVDF?

In a relatively basic and technical definition, PVDF is an artificial material that is produced by polymerization of vinylidene fluoride. Among the different types of plastic, it is considered one of the unusual ones that are used for relatively specific and specific purposes.

What can be produced from PVDF?

In principle, almost any plastic product can be made from it since it is easy to process. But it is advisable and acceptable to use it where its special advantages are manifested, for example in the field of construction. And if you want a more special example – in the processing of nuclear waste. It also has unusual uses, such as a component in high-quality metallic paints.

In conclusion

This is a special type of plastic. It is definitely important and should also be taken into account when planning production in plastic or in combination with plastic parts.
