What is PVDF? Common questions and answers.

Polyvinalidene Fluoride Tubing, or PVDF for short, is a versatile and extremely dependable product that is perfect for many different jobs. However, as with any other tool on the market, it works best when utilized properly If you are interested in using PVDF Tubing for your company’s projects, it may be helpful to understand many of the unique or interesting qualities of Polyvinalidene Fluoride before beginning. Below are detailed answers to some of the most commonly asked questions regarding PVDF.

What are the highest and lowest temperatures at which PVDF Industrial Tubing can be used?

Under traditional circumstances, PVDF can be used safely at up to 150C. Most manufacturers suggest that it be used at no higher than 140C with chemicals that have little attack on PVDF. The lowest possible temperature one should expose PVDF tubing to is -40C, though tests have shown that it may resist becoming brittle at as low as -30C.

What is the Preferred Method of Uniting PVDF Tubes?

The most common method of combining PVDF Tubing is through the use of machinery or the process of fusion welding. PVDF systems can also be acquired from manufacturers in the following styles:

  • Socket fusion
  • Flanged mechanical
  • Electrofusion
  • Sanitary mechanical
  • Threaded mechanical
  • Forced mechanical
  • Plastic lined steel flanged
  • Fiberglass reinforced flanged
  • Threaded
  • Butt fusion
  • Beadless butt fusion
  • Infrared fusion

Can PVDF Tubing be Exposed to Nuclear Radiation?

Government laboratories have found that PVDF Tubing can be used at up to 1,000 Mega-Rads of radiation exposure without negative effects. It is always suggested, however, that facilities do personal investigation before engaging in potentially harmful radiation experiments with new materials.

Does PVDF Tubing Resist Sunlight?

In short: very much so. Due to PVDF’s exceptional resistance against the sun’s rays, it is frequently found in solar panels expected to last for over 40 years. Under the intense sun of Florida and California, PVDF showed little to no deterioration in several tests.

What is the Best Method to Clean PVDF?

While traditional methods of washing with soap and industrial cleaner are technically the best way to clean PVDF, frequently this option is not available. In these circumstances, it is suggested that you use steam cleaning. PVDF has been shown to remain free of deterioration after undergoing 50 continues cycles at 125C. It has also been a fairly common practice to subject PVDF tubing to low pressure steam in various different applications.
