Industry Technological Innovation Drives Performance Upgrading of Waterproof and Breathable Membranes

Recently, a number of enterprises in the industry have made breakthroughs in the R&D of waterproof and breathable membrane technology. A well-known enterprise has made progress in the manufacturing of expanded polytetrafluoroethylene (ePTFE) materials by improving production processes. The new ePTFE breathable membrane has a more uniform and tiny pore size distribution, which can increase the waterproof grade to above IP69K, effectively resisting high-pressure water spray and strong water flow impact. At the same time, its air permeability has increased by 30% compared with the previous generation, enabling faster balancing of internal and external pressure of equipment and reducing potential risks caused by pressure differences.​

In addition, some enterprises have innovated in material composite technology by combining nano-coatings with traditional waterproof and breathable membrane materials. This new type of composite membrane not only has excellent waterproof and breathable performance but also enhances chemical corrosion resistance, making it adaptable to harsh environments involving corrosive substances such as pesticide packaging. This has greatly expanded the application scope of waterproof and breathable membrane series products and injected new impetus into the development of the industry.
