Air purification membranes are in strong demand in the field of environmental protection and my country has raw material advantages

Air purification membrane refers to a film formed from polytetrafluoroethylene as raw material through expansion, calendering and biaxial stretching. Air purification membranes have the advantages of large porosity, small pore size, corrosion resistance, high temperature resistance, green environmental protection, and good flame retardancy. They have broad application prospects in environmental protection fields such as industrial dust removal, protective materials, automotive air purification, and indoor air purification.

The core raw material of air purification membrane is polytetrafluoroethylene (PTFE). PTFE has the advantages of good chemical stability and acid and alkali resistance. Its film products can be used as filter materials in construction engineering, pharmaceuticals, water treatment, air purification and other fields. my country is a major producer of polytetrafluoroethylene. In recent years, with the continued efforts of local enterprises, my country’s polytetrafluoroethylene production capacity has expanded rapidly, and the industry has shown an oversupply situation. Against this background, my country’s air purification membrane production is showing a growth trend.

According to the “2023-2028 China Air Purification Membrane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Air purification membranes are mainly used in industrial dust removal, protective materials, automotive air purification, indoor air purification and other fields. In the field of industrial dust removal, air purification membranes can be used to produce cartridge dust removal equipment and bag dust removal equipment; in the field of protective materials, air purification membranes can effectively filter haze particles and have anti-bacterial and anti-virus effects. Protective masks, Medical protective clothing, etc. are its end products; in the field of air purification, air purification membranes can be used to produce air purifiers, air disinfection machines, air conditioning filters, etc.

In recent years, our government has attached great importance to the problem of air pollution and introduced many policies to deal with it. In June 2022, seven departments including the Ministry of Ecology and Environment, the National Development and Reform Commission, and the Ministry of Industry and Information Technology jointly issued the “Implementation Plan for Synergetic Efficiency in Pollution Reduction and Carbon Reduction”. The document clearly proposed to increase the prevention and control of air pollution and strengthen pollution reduction and carbon reduction related technologies. , equipment research and development investment. Air purification membranes have the advantages of small filtration resistance and high filtration efficiency. Driven by national policies, as environmentally friendly materials, they will be widely used in the process of air pollution control.

Compared with developed countries such as Europe and the United States, my country’s air purification membrane industry started late and its technical level is relatively weak. Xingyuan Materials, Zaisheng Technology, Jiuding Environmental Protection, Sage Technology, etc. are the main players in my country’s air purification membrane market. In the future, with the improvement of independent research and development capabilities of local enterprises, my country’s air purification membrane industry will gradually develop in a high-quality direction.

Industry analysts said that as an environmentally friendly product, air purification membranes have the advantages of corrosion resistance and high temperature resistance, and have a wide range of applications. In the future, as market demand is gradually released, the development speed of my country’s air purification membrane industry will accelerate. In recent years, Chinese enterprises and scientific research institutions have continued to increase investment in the research and development of high-end air purification membranes. It is expected that the localization process of my country’s high-quality air purification membrane market will accelerate in the future.
