Introduction of PVDF Powder Injection FR906
It is typically a semi-crystalline polymer that is approx. 50% amorphous. It has highly regular structure with most of VDF units joined head-to-tail with very less percentage of monomer units joined head-to-head.
This fluoroplastic exist in four possible conformations named as α, β, γ, and δ phase.
The C–F bonds are polar and the highest dipole moment is obtained with the alignment of all dipoles of the polymer in the same direction, corresponding to the β-phase of the PVDF. β-phase is the desirable phase to its piezoelectric characteristics of the polymer.
The dipole moments of α crystallites are oriented in opposite directions, resulting in a zero net polarization.

Chemical industry: molded, extruded, injection molded PVDF lining or fully plastic valves, pumps, pipes, fittings, tower fillers and other products. A large number of PVDF valves are used in advanced ion-exchange membrane caustic soda production units.
Cable and electronic industry: with the development of domestic construction industry, PVDF wire and cable with excellent flame retardancy and low smoke has become a hot market product, which is imported from abroad. High capacity microcapacitors with high dielectric constant PVDF thin film molding has unique advantages, has become the preferred material in the electronic industry. PVDF piezoelectric film is now made of laser detectors.
