Recently, the application of waterproof and breathable membrane series products, such as waterproof and breathable gaskets, waterproof and breathable plugs, and waterproof and breathable covers, has made significant progress in multiple emerging fields. In the smart wearable device sector, due to the miniaturization of products and frequent contact with human sweat and external water vapor, there are extremely high requirements for waterproof and breathable performance. Relying on their precise microporous structure, relevant products can effectively block liquid water while allowing water vapor molecules to pass freely, thus protecting the internal electronic components of the devices, preventing malfunctions such as short circuits caused by moisture erosion, extending the service life of the devices, and enhancing user experience. Their market penetration rate is steadily increasing.
In the field of medical equipment, especially portable medical monitoring instruments, it is necessary to ensure waterproofing during use to prevent liquid contamination affecting detection accuracy, while also requiring breathability to balance internal pressure and avoid damage caused by pressure changes. The application of waterproof and breathable membrane series products enables medical equipment to operate stably in complex usage environments, providing strong support for the development of the medical and health industry, with market demand showing a rapid growth trend.
