Characteristics
¡òPTFE membrane adopts 100% natural and permanent hydrophobic
membrane material
¡òIt 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
¡òIt holds the opposite capability against hydrophilic membrane

Applicable Fields :Filtration for air, gas and hydrophobic chemicals
¡òPTFE membrane possesses extremely strong chemical compatibility
¡òIt can almost filter all the organic solvents and strong corrosive chemicals
¡òIf hydrophobic PTFE membrane is used to filter hydrophilic liquid, please soak the membrane into ethanol andisopropanol liquor beforehand so the hydrophilic liquid
