Hydrophobic PTFE Membrane for Medical Filters of Air Venting

PTFE membrane, the full name is Polytetrafluoroethylene membrane, abbreviation FTFE or F4. The PTFE venting membrane provided by membrane solutions has strong hydrophobicity and oleophobicity, and the gas can pass through while preventing water vapor, volatile organic compounds, and acid gases from passing through. It is widely used in medicine, cycling industry and other system protection

.

PTFE membrane is semi-porous layer of PTFE bonded to the surface of a filter. This filter membrane acts at a permanent dustcake, capturing incoming dust particles (i.e. particulate matter or PM 2.5) on the surface of the filter (surface filtration) as opposed to normal filters that require a thick layer of dust buildup (dustcake) to actually reach peak efficiency.

XINNA is an ISO Certified high-tech enterprise dedicated to manufacturing, supplying and sales of membrane filters for healthcare industries since 1994. The PTFE membranes are produced in our 100,000 grade clean-rooms, each and every bulk were tested in our laboratories before packaging and delivery, safety and quality guaranteed. PTFE membranes from us can be offered in various pore sizes and cut-to-size rolls, flat sheets and discs to meet your specific application needs.

Features

• High air permeability
• Strong hydrophobicity
• Wide chemical resistance
• Good membrane uniformity
• High mechanical strength

​Applications

Hydrophobic PTFE membranes are extensively used for air venting and gas filtration in medical, healthcare and bio-tech industries, including

• Petrochemical and chemical processing: It is the material for the choice of gaskets, pump interior, vessel lining, rings, seals, spacers, dip tubes, and suitable drilling components. This is why it is corrosion resistant and then chemically inert.
• Laboratory application: The PTFE tubing, piping, and vessels are used in various laboratory wares. This is because of the chemical resistance, inertness, and no contamination after the surface.
• Electrical appliances: The PTFE is one of the topmost best insulators, as you know. The thick wall close tolerance extrudes the tubing into the PTFE shape as of choice, where the machining and then drilling long length. It can be machined onto the stand-off insulators.
• Food and pharmaceutical industries: The virgin PTFE has been approved by the FDA in order to use in the food,cosmetics,beverages, and pharmaceutical industries. It can withstand high temperatures.
