How Waterproof vents work

Generally, the breathable film used in Waterproof vents is based on the principle of micropores. During the construction process, it is easy to wear and easily block the micropores, resulting in the inability to breathe or the enlargement of the micropores, resulting in material leakage, which means that the material loses its own breathable and waterproof functions. Waterproof vents, adding a hydrophilic group to the polymer vapor-permeable film, through the hydrophilic properties of the hydrophilic group, the water droplets cannot penetrate and the water vapor can freely pass through, ensuring the stability of the vapor-permeable and waterproof performance of the product itself and the longevity of the service life durability.
