Material Resistance

  • ePTFE is inherently resistant to corrosive elements in seawater
  • It is chemically inert and does not react with saltwater or the ions within it
  • This inertness means the vent remains stable when exposed to seawater, avoiding degradation

Barrier Protection

  • ePTFE vents act as a barrier that prevents seawater from entering internal components
  • The microporous structure blocks liquid seawater while allowing air and vapor to escape
  • Prevents salt residues from corroding circuit boards, sensors, and batteries

System Integration

  • ePTFE vents work in tandem with the device's broader waterproofing systems
  • When combined with sealed casings, they create comprehensive defense against seawater
  • Enables devices to withstand ocean swimming and accidental splashes without erosion damage

By keeping seawater out, ePTFE vents directly reduce the risk of internal erosion that would otherwise shorten device lifespan. Their effectiveness is closely tied to how they integrate with the device's overall design.
