Microporous membranes have a wide range of applications. PTFE microporous membranes are the mainstream products in the market.

There are many types of polymer membranes, including composite membranes, porous membranes, fiber membranes and dense membranes. Microporous membrane is a subdivided product of porous membranes. Its pore size is between 5 nanometers and 1 millimeter. It has the advantages of stable chemical properties, high temperature resistance, good flexibility, low viscosity, and corrosion resistance. It can be used as ultrafiltration membrane and microfiltration membrane. Membranes are widely used in many fields such as medical treatment, food processing, chemical industry, etc. According to different substrates, microporous membranes can be divided into ultra-high molecular weight polyethylene microporous membranes, polytetrafluoroethylene microporous membranes, polyamide microporous membranes, etc.

Polytetrafluoroethylene microporous membrane, also known as PTFE microporous membrane, is a mainstream product in the microporous membrane market. It is made of polytetrafluoroethylene as the base material and has uniform pore size distribution, high porosity, high elasticity, good flexibility, With the advantages of being impermeable and breathable, it is widely used in clothing, medical, environmental protection and other fields. Benefiting from the increasingly strong market demand, the production capacity of polytetrafluoroethylene microporous membrane continues to expand and the output continues to grow. Taking expanded polytetrafluoroethylene microporous membranes as an example, global output of expanded polytetrafluoroethylene microporous membranes will reach nearly 12,000 square meters in 2022, setting a record high.

The main preparation methods of microporous membranes include self-assembly method, electrochemical method, template method, vapor deposition method, electrospinning sintering method, sol-gel method, uniaxial stretching method, pore-forming method using pore-forming agents, and bidirectional stretching. Stretch forming method, etc. At present, the biaxial stretching molding method is widely used in the preparation process of microporous membranes in my country. It has the advantages of good finished product quality and high production efficiency, and is suitable for continuous production.

According to the “2023-2028 China Microporous Membrane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Microporous membranes are widely used in many fields such as medical, food processing, and chemical industries. In the medical field, microporous membranes can be used as intravenous injection filter membranes, medical packaging membranes, drug filtration membranes, etc.; in the food processing field, microporous membranes can be used to remove impurities in juice, beer, dairy products, and carbonated drinks; in the chemical industry In the field of water treatment, microporous membranes can be used in wastewater treatment systems in chemical plants. In the future, as the scope of applications continues to expand, the market demand for microporous membranes will further grow.

Fosu Technology, Sinoma Technology, and Wels Technology are the main manufacturers of microporous membranes in my country. In recent years, attracted by market prospects, the number of companies in my country’s microporous membrane industry has continued to grow. It is expected that in the future, companies with independent research and development and production capabilities for high-performance microporous membranes will occupy a larger space in the Chinese market.

          Industry analysts said that as a polymer membrane, microporous membrane has a wide range of uses, and the development trend of the industry continues to improve. Benefiting from technological progress, the production and quality of microporous membranes in my country have continued to improve. PTFE microporous membrane has excellent comprehensive properties and is a mainstream product in the microporous membrane market. As the demand for its application grows, the prosperity of my country’s microporous membrane industry has been further improved.
