Polyvinylidene Fluoride Membrane filter Cartridges (PVDF)
Materials of Construction
Cartridges membrane is folded with PVDF membrane and diverting layers. Cartridges cover, housing and central pole are all made of PP. All parts are sealed by hot welding technology without any chemical infectant.
Features and Benefits
It is hydrophobic membrane with small adsorptance.
Possessing better performance of oxidation resistance and heat-resistance and is extensively applicable.
After being soaked with 30% alcohol, it can be used for liquid filter, It can continuously work at high temperature (90 degree c).
Experiencing 100% integrity test before ex-factory.
