How is waterproof breathable film widely used in consumer electronics ?
With the development of science and technology and the diversification of the application environment, the sealing reliability of electronic components is facing more and more challenges, and the protection of electronic components has put forward higher and higher requirements. In the electronics industry, waterproof breathable vent is mainly used for sensors, gas detectors, batteries, hearing aids, cameras, digital cameras, underwater equipment and test instruments, products in various forms, including adhesive-backed products, threaded breathers, breathable plugs and a variety of injection molded products designed in conjunction with customers.

Waterproof breathable membranes are used in the electronics industry, with product protection ratings up to IP67 and IP68, ensuring good breathability while ensuring seal integrity and overall reliability of electronic components.

The waterproof membrane vent is made from a flexible and elastic microporous material, expanded polytetrafluoroethylene (e-PTFE). This e-PTFE microporous material has a high porosity and uniform pore size distribution, offering breathability, low friction coefficient, and minimal adsorption. It is not only dust-proof but also oil and water-repelling, with micro heat dissipation stability, chemical resistance, and UV resistance. It can sustain its breathability function at temperatures ranging from -40°C to +150°C.

The waterproof and breathable membrane manufacturer’s adhesive-backed waterproof membrane enhances water resistance (against various liquids) while ensuring ample airflow. Even under significant pressure differences, it can instantly balance, preventing liquid molecules from permeating to the other side and equalizing internal and external pressures to prevent potential issues. The waterproof breathable membrane patches from the manufacturer are easy to install and can be directly adhered to sealed housings.
