PVDF Tubing

About PVDF Tubing

PVDF tubing (PolyVinyliDeneFluoride) enjoys inherent high purity, has smooth internal surfaces and exhibits very low fluid permeation through its wall making it ideal for the transport of ultra-pure fluids in the pharmaceutical and semi-conductor industries.

PVDF tubing is used widely in pure water systems thanks to PVDF containing no additives or damaging metal ion ‘extractables’ but such tubing is also used in municipal water treatment where its resistance to strong disinfecting solutions is an advantage.
