All About PVDF: Extreme Chemical Resistance

For applications that need high chemical resistance to solvents, acids, and bases, we often recommend Polyvinylidene Difluoride (PVDF).

PVDF is a highly chemically resistant crystalline thermoplastic used across many industries but is most popular in the chemical processing industry due to its outstanding chemical and solvent resistance, good corrosion resistance, good thermal stability, outstanding UV resistance, and low flammability.

Because of its good chemical properties, it’s safe for use even in the most strict environmental environments such as healthcare and pharmaceuticals, biomedical research, ultra-pure applications (like to transport ultra-pure water), and in food and beverage processing.

Here are some of the key properties of PVDF thermoplastics:

  • Excellent resistance to creep and fatigue
  • Excellent thermal stability
  • Excellent resistance to radiation
  • Often used as insulation and protection cover in chemical applications
  • UV resistant (does not age)
  • High dielectric constant
  • Working temperature from -20°C to +130°C

If you’re working on a project that requires very specific high levels of purity and chemical resistance, consider PVDF. We’d be happy to chat more about the details of this specialty thermoplastic with you directly as well. Contact us for more information or a quote.
