As explained in the previous blog post - IP Ratings Explained - an Ingress Protection (IP) Rating is a common international test method (IEC 60529) to rate enclosure protection from objects and liquids.  IP67 refers to the most extreme IP rating certifying that the enclosure will protect against the entry of dust (6) and the effects of immersion in water to depth between 15cm and 1meter for 30 minutes (7).  

Applications that require IP67 protection:

  • Electronic Components
  • Computer Equipment
  • Telecommunications
  • Consumer Appliances
  • Commercial Electronics
  • Lighting
  • Energy Generation and Storage

These applications require venting enclosures, which are designed to keep moisture and dust out while allowing air to flow in and out of the device.  


POREX® PTFE membrane material is ideal for such applications.  Vents made with POREX PTFE are hydrophobic and oleophobic, pressure compensating elements to protect electronic enclosures and housings from pressure build-up and water intrusions.  It is also IP67-rated.  Click here to read more about POREX PTFE Membrane.
