Hydrophobic Polytetrafluoroethylene Membrane(PTFE),China T.S Filter price supplier

product details

Model No:Membrane(PTFE)

Standard:GB-9688-88 and GB/T17219-1998

Origin:China

Brand:T.S Filter

Characteristics

PTFE membrane adopts 100% natural and permanent hydrophobic

membrane material

It can ensure wet air and other gas pass through smoothly, even when the

differential pressure is very low. But the water liquid can ’ t permeate

It holds the opposite capability against hydrophilic membrane

Validation

Bubble Point value for 0.2um membrane experiences Bacteria Challenge testing, ensuring the reliability of sterilization filtration.

Applicable Fields : Filtration for air, gas and hydrophobic chemicals

PTFE membrane possesses extremely strong chemical compatibility

It can almost filter all the organic solvents and strong corrosive chemicals

If hydrophobic PTFE membrane is used to filter hydrophilic liquid, please soak the membrane into ethanol andisopropanol Liquor beforehand so the hydrophilic liquid
