In modern electronics and industrial devices, Waterproof Breathable Vents have become essential components to protect sensitive equipment from moisture, dust, and environmental damage. Among various materials, ePTFE vent technology stands out for its superior performance in waterproof vent and breathable vent applications.

​Waterproof Breathable Membrane Material is an advanced engineered material designed to provide high-level water resistance while maintaining excellent vapor permeability. This combination of properties ensures protection against liquid ingress without compromising comfort or breathability, making it ideal for outdoor apparel, footwear, protective gear, medical equipment, and industrial applications.

Car battery safety has been a hot topic in China. At present, PUW's R & D and design of explosion-proof valves, designed for automotive battery packs, battery boxes and other explosion-proof waterproof breathable products, successfully solved the problem of automotive battery explosion. It has been widely used in pure electric cars, hybrid cars, new energy hybrid cars, hybrid cars and other batteries to promote the rapid development of automotive batteries.
