PVDF Piping System
KYNAR® PVDF Piping System has outstanding barrier properties, which allow better protection of the environment from leakages of hazardous chemicals. KYNAR PVDF Pipe Fittings is a polymer containing carbon, hydrogen, and fluorine. Fluorine, the giant molecule, ensures the stability of the polymer chain. PVDF Pipes are considered one of the most inert substances on earth. It has the advantage of absolute corrosion suppression, even under varying process conditions, compared to other materials. Fittings KYNAR® PVDF has the characteristic properties of high resistance to chemical attack intrinsic to all fluoropolymers based on the increased strength of the carbon-fluorine atom bond.
