The waterproof requirements of consumer electronics are gradually increasing, and ePTFE film is the preferred material for both waterproof and dustproof and sound-permeable applications. ePTFE film is applied to the crevices and slots of smart wearable products to achieve waterproof and dustproof levels, and to maintain the best signal-to-noise ratio and the lowest distortion after sound passes through the waterproof film.

ePTFE film is waterproof and breathable, which ensures the flow of gas inside and outside the device, eliminates the pressure difference between inside and outside the device, and prevents liquid water, dust, and pollutants from outside the device from entering the device and causing faults of sensitive electronic components.

In addition, sound waves can easily and quickly pass through the micropores of ePTFE's waterproof sound-permeable film, transmitting sound well from inside to outside or from outside to inside, maintaining a high level of sound quality. The thin and lightweight waterproof breathable membrane makes it ideal for devices placed in limited Spaces.
