Breathable Membrane Material

Breathable Membrane Material is a high-performance barrier film engineered to allow air and moisture vapor to pass through while preventing liquid water from entering. Designed using advanced ePTFE (expanded polytetrafluoroethylene) technology, this microporous breathable membrane combines excellent Waterproofing, breathability, and durability.
It is widely used in industries that demand moisture management and long-term protection — including electronics, outdoor lighting, medical devices, sensors, batteries, and automotive systems.
PUW, a leading breathable membrane manufacturer and supplier in China, provides custom breathable membrane materials and OEM waterproof breathable membranes to meet diverse industrial requirements.
