PVDF / Kynar® Compression Molding

PVDF (polyvinylidene fluoride) is a fluorinated semi-crystalline thermoplastic that is obtained by polymerizing vinylidene fluoride.

When exposed to harsh chemicals, high temperatures and UV radiation, PVDF exhibits the characteristic stability of fluoropolymers.  PVDF exhibits higher dimensional stability, pressure resistance and tensile strength than PTFE, but lesser friction and insulation properties.
