PVDF/PTFE membrane

Hydrophobic fluoroplastic (PTFE, PTFE + PVDF) membrane (MFFK)

Description

The composite hydrophobic membrane MFFK is a porous membrane made from copolymer of PTFE and PVDF supported by various nonwoven materials (polypropylene, lavsan) with micron ratings 0.15; 0.25; 0.45; 0.65; 0.8 μm and total porosity 80-85 %.

Applications

• Prefiltration and sterilizing filtration of air and gas.

• Microfiltration of aggressive chemicals and reagents.

• Microfiltration of alcohols, hydrocarbons, oils, acids, alkalis, organic solvents (except for ketones, esters, amide solvents).

Approved by the Ministry of Health for operation in contact with blood.

For filtration of aqueous solutions treatment of Filter Disks MFFK with aliphatic alcohols (or aqueous solutions) is required.

Hydrophilic fluoroplastic (modified  PVDF) membrane (MFFK-G)

Description

The composite hydrophilic membrane MFFK-G is made from modified hydrophilic polyvinylidene fluoride with low binding properties and wide chemical and temperature resistance.

Applications

• Microfiltration of aqueous solutions including aggressive ones.

• Antiseptic filtration of water.

• Microfiltration of aggressive media including gases.

• Microfiltration of alcohols, hydrocarbons, oils, acids, alkalis, organic solvents (except for ketones, esters, amide solvents).

Approved by the Ministry of Health for operation in contact with blood.
