  • Membrane For Consumer Electronics

    With the rapid development of consumer electronics and IoT, as well as the widespread adoption of 4G/5G communication, consumer scenarios have become more diverse. Consumers now demand higher standards for mobile phones, wearable devices, and other mobile electronic devices. Conventional consumer electronic products are designed to be sophisticated and lightweight. However, during transportation and daily use, changes in temperature and external air pressure can cause imbalances in pressure inside and outside the product, leading to seal failure and problems like liquid infiltration or dust contamination, ultimately resulting in product failure.

    JNS is a company dedicated to providing comprehensive ePTFE solutions. They can assist design engineers in achieving products that maintain a breathable function and balance pressure differentials while maintaining excellent acoustic performance under sealed and waterproof conditions.

  • FEATURES

    Excellent breathability enables rapid pressure equalization within the product's structure, reducing sealing pressure on the product's structure.

    Maintains water vapor balance inside and outside the chamber, protecting sensitive electronic devices from condensation.

    Lightweight and thin with excellent breathability, meeting high acoustic performance requirements.

    Enables electronic devices to meet waterproof and dustproof requirements for various application environments.
