PVDF (Polyvinylidene Fluoride)

PVDF is a melt processable fluropolymer. It is similar in properties to other fluropolymers, but has better strength and lower creep than the other members of this family. PVDF has good wear resistance , and excellent chemical resistance. But does not perform well at elevated temperatures.

Applications: Aircraft applications, Computer components, Protective coverings, Seals, Electrical parts, Diaphrams.
