Waterproof and breathable membranes are widely used, with construction and electronics being its main application areas.

Waterproof and breathable membrane, referred to as breathable membrane, is a breathable and impermeable film, which is a new type of polymer waterproof material. According to different raw materials, waterproof breathable membranes can be divided into polyethylene (PE), thermoplastic polyester elastomer (TPEE), thermoplastic polyurethane elastomer (TPU), polytetrafluoroethylene (PTFE) breathable membranes, etc.; depending on the structure, they can It is divided into microporous breathable membrane, hydrophilic breathable membrane, microporous hydrophilic breathable membrane, etc. Among them, PTFE waterproof breathable membrane is the latest generation of breathable membrane products with great development potential in China.

Waterproof and breathable membrane is a new type of membrane with good temperature resistance, strong corrosion resistance, good dustproof and oil resistance, good weather resistance, low adhesion, good waterproofness, non-toxic and harmless, and strong anti-aging performance. Waterproof materials are currently used as electronic component protection materials and building waterproof materials in the fields of automobiles, electronics, photovoltaics, communications, LED lights, security, medical equipment, home appliances, construction, etc., with a wide range of application scenarios.

Among them, electronics and construction are the main application areas of waterproof and breathable membranes. In the electronics field, waterproof and breathable films are mainly used in parts manufacturing scenarios such as lamps, instruments, sensors, batteries, camera modules, etc., playing the roles of waterproofing, dustproof, oilproof, anti-condensation, and anti-fogging, thereby achieving effective The purpose of extending the service life of equipment; in the field of construction, waterproof and breathable membranes are mainly used in scenarios such as building roof waterproofing, underground moisture-proofing, insulation wall steam insulation, dam anti-seepage, pipeline anti-seepage, etc., playing a role in waterproofing, dustproof, anti-seepage, moisture-proof, Insulation, breathability, UV resistance and other functions, thereby achieving the purpose of building energy saving.

In recent years, as the market penetration of mobile phones, computers, tablets and other equipment has increased significantly and the output value of the construction industry has continued to increase, the market demand for waterproof and breathable membranes, as a key waterproof material for electronic equipment and building roofs, has continued to increase. According to the “China Waterproof Breathable Membrane Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center , the domestic waterproof and breathable membrane market size will be around 2.5 billion yuan in 2022. In the future, as the trend of global semiconductor transfer to China continues to deepen and national policies vigorously promote the development of the green building materials industry, the scale of the domestic waterproof and breathable membrane market is expected to maintain a sustained growth trend, and the industry development prospects are good.

Industry analysts said that the current major international companies in the waterproof and breathable membrane market include the German RKW Group, the American Gore, the American Donaldson, American ZEUS, American Agutec, French Saint-Gobain Group, Japanese Mitsui Chemicals, etc.; domestic companies mainly include Yaco Film, Haiwei Nonwoven Fabrics, Lesso Wanjia Technology, Annuo Filtration, Fo Plastic Technology, Shunchang Plastic, etc. There are currently a large number of domestic waterproof and breathable membrane companies. However, due to the lack of established industry standards, domestic products are mainly concentrated in the low-end market and their product competitiveness is weak. Therefore, the current domestic waterproof and breathable membrane market is still dominated by leading foreign companies. In the future, domestically produced products There is huge room for alternatives.
