Engineering 185°F - 300°F | Polyvinylidene Fluoride (PVDF)

KYNAR® 740 PVDF

KYNAR® PVDF is a highly chemically resistant crystalline thermoplastic. It is used extensively in the chemical processing industry because of its properties which include:

  • Outstanding chemical and solvent resistance
  • Good corrosion resistance
  • Good thermal stability
  • Outstanding UV resistance
  • Low flammability

KYNAR® PVDF is a highly chemically resistant crystalline thermoplastic.
