Breathability & Water-Pressure Capability
| Tier | Breathability (ml/min @ Ø10 mm, 7 kPa) | Water pressure | Typical application |
|---|---|---|---|
| Low breathability (high waterproof) | 200–1,000 | 50–30 m | Deep-water / harsh waterproof; custom per spec |
| Mid (balanced) | 1,000–5,000 | 30–2 m | Automotive / general outdoor; custom per spec |
| High breathability | 5,000–12,000 | 10–1 m | High heat dissipation / low waterproof need; custom per spec |
Mimoyin does not sell fixed catalog SKUs. For each project we match the membrane material to your drawing and required breathability, acoustic loss, and water pressure, then produce samples for your validation testing.
