SELENE ePTFE membrane microstructure — expanded PTFE node-and-fibril architecture
ePTFE Membrane
Higher Performance ePTFE

Defends cleaner environments.

A node-and-fibril microstructure delivers billions of pores per square centimeter — small enough to block liquids, aerosols and sub-micron particulates, yet open enough to breathe. SELENE ePTFE is engineered for the most demanding electronics, semiconductor, medical and outdoor apparel programs, sustaining performance across extreme temperature and chemical envelopes.

  • Pore size 0.1–3 μm
  • IPX7 · IPX8 rated
  • −40 °C to +260 °C
  • Chemically inert
SELENE acoustic vent — precision mesh membrane assembly for portable electronics
Acoustic Vents
Clear Sound · Advanced Protection

Trusted by leading OEMs.

SELENE acoustic vents repel dust, liquid and contaminants while preserving crisp, consistent sound reproduction. Customizable in size, shape, protection class and mounting format, they scale from earbuds and smartphones to wearables and deep-immersion enclosures — meeting the tightest miniaturization targets without compromising acoustic transparency.

  • Ø 1.5–8 mm formats
  • Low insertion loss
  • Adhesive · press-fit
  • MEMS-compatible
