Waterproof breathable membrane series
A waterproof breathable membrane is a special functional material designed to achieve both waterproof and breathable (or moisture-permeable) properties simultaneously. Simply put, it can block the passage of liquid water (like rain or sweat) but allows water vapor (such as human perspiration) molecules to pass through freely.
Functions
Waterproof breathable membranes primarily block water and wind while allowing water vapor (perspiration) to escape. This keeps the internal environment dry and comfortable, helps balance internal and external pressure, and prevents dust entry.
Principles
Micro-porous: Tiny holes block water droplets but let vapor through.
Non-porous: Special material absorbs and moves water vapor, blocking liquid water.
Application Areas
Found in outdoor gear (jackets, shoes), buildings (roofs, walls), electronics, and medical products.
Advantages
Comfort: They keep you dry, leading to a more comfortable feeling.
Versatility: They are simultaneously waterproof, windproof, and breathable.
Protection: They safeguard internal components from moisture and environmental damage.
