Automotive Vents

POREX Automotive Venting Membranes are hydrophobic and oleophobic, pressure compensating elements to protect electronic control systems from pressure build-up and water intrusion. Typical examples include:

  • Engine Management Systems
  • Headlights
  • Tyre Pressure Monitoring Systems
  • Electric motor housings
  • Anti-lock Braking System
  • Traction Control System
  • Air bags

Gas Sensor Vents

POREX® Venting Membranes are used for protection of an electrochemical sensor and are usually coated or printed by the customer with a catalyst. The membranes are easy to handle and dimensionally stable during the sintering or printing process. POREX® Membranes are also hydrophobic, breathable, and either laminated to a strong PP mesh or robust in itself. They can be used as a “dust cover” without interfering with the performance of the electrochemistry. POREX Venting Membranes can control the flow of gas into the sensor to a slow but steady flow.

Cap Closure Vents

Hydrophobic and oleophobic vented closures on a sealed container balance the pressure between the interior and the atmosphere without loss or contamination of the contents. In liquid packaging, especially of hazardous chemicals, there is a high need for vented caps and closures. POREX® Membranes are an effective and low-cost industry recognized solution to this problem. Using a single-component membrane reduces installation cost and time. The inherent membrane strength ensures reliable and repeatable performance in demanding automated welding processes, needing no housing or molded support for assembly.

IV Catheter Vents

Standard IV catheter insertion procedure is to advance the catheter into a vein until blood is seen in the “flash chamber” of the catheter. POREX® Porous PTFE Vents with ETO or steam sterilization compatibility help create a breathable liquid barrier that prevents blood bypass through the vent.




Chromatography Frits

POREX® Porous PTFE Chromatography Frits are used in a wide variety of sample preparation and high throughput applications. In classic SPE (Solid Phase Extraction) columns, POREX® PTFE Frits facilitate column flow through; allow for organic solvent filtration and high sensitivity analyses. Specially treated PTFE frits used in protein precipitation & crash plate applications help improve the removal of unwanted proteins from biological samples.
