Custom Waterproof Breathable Membrane

Model: PUW575

The Custom Waterproof Breathable Membrane is a highly customizable material that offers both water resistance and breathability for specialized applications. Tailored to specific requirements, it provides optimal protection while maintaining air permeability. Ideal for high-performance clothing, industrial applications, and medical devices, it ensures that moisture is kept out while allowing for efficient air exchange, delivering comfort and safety.
Product Details

The Custom Waterproof Breathable Membrane is an innovative material engineered to provide outstanding waterproofing performance while maintaining superior breathability. Designed for industries where both protection and air exchange are essential, it combines advanced polymer technology with customizable specifications to meet diverse functional requirements. As a professional custom breathable film manufacturer and Waterproof Membrane supplier, we offer tailor-made solutions for applications in apparel, industrial equipment, medical devices, automotive components, and electronic products.

Custom Waterproof Breathable Membrane

Excellent Combination of Waterproofing and Breathability

Unlike traditional waterproof layers that trap heat and moisture, the Waterproof Breathable Membrane allows air to pass through while blocking external water intrusion. This unique dual-function structure ensures long-term comfort, prevents condensation, and enhances product durability.
By adjusting the microporous structure, thickness, and surface coating, the membrane achieves different levels of water resistance and air permeability, suitable for various environmental conditions.
