POLYVINYLIDENE FLUORIDE (PVDF)

Advantages

  • Strength/stiffness
  • Chemical Stability
  • Nonflammability

Limitations

  • Cost
  • Incompatibility with glass fiber

Overview

Polyvinylidene fluoride (PVDF) is one of the most rigid and abrasion resistant of the melt-processible fluoropolymers. It has good chemical resistance, though hot sulfuric acid and hot amines can attack it.

Like most fluoropolymers, PVDF is inherently flame retardant. It retains useful mechanical properties until 300 degrees F (149 degrees C).
