The Advantages Of PTFE Filter Membrane

PTFE filter membrane (aperture size 0.03-5 micron) has achieved the perfect combination of high flow rate, high precision and high cost performance. The unit area has more micropores, uniform pore size and small diffusive flow. The PTFE filter includes hydrophobic membrane and hydrophilic membrane. It has a wide range of specifications and can be widely used for gas filtration and liquid filtration.


Hydrophobic membrane: high flow rate


Advantage:

Intrinsic hydrophobicity

High velocity

High filtration precision

Clean, no shedding, low soluble substance

Long service life

Chemical resistance, high temperature resistance


Application:

Gas filtration

Organic solvent filtration

Strong corrosive chemical filtration

Filtration of high purity chemicals

The higher opening rate makes the flux greater under the same filtration accuracy or higher filtration accuracy under the same flux.


Hydrophilic membrane: permanent hydrophilicity; contact angle <20 degree


Advantage:

Strong hydrophilicity and permanent hydrophilicity

High velocity

High filtration precision

Clean, no shedding, low soluble substance

Long service life

Chemical resistance, high temperature resistance

No pre wetting

Dry preservation


Application:

Aseptic filtration of various water-soluble solvents in the pharmaceutical industry

Microelectronic semiconductor

Aseptic filtration of eyedrops, antibiotics

Aseptic filtration of strong corrosive solvents and organic solvents

Filtration of highly corrosive water soluble chemicals
