China's industrial filtration industry analysis: the market continues to expand high-performance filter materials into the development direction

1. Overview and industrial chain diagram

There are many types of industrial filter materials, which can be divided into flexible filter materials (such as woven, non-woven materials and organic membranes, etc.), rigid filter materials (such as sintered metal fiber felt, ceramic membranes, etc.) and loose filter materials (such as Activated carbon, diatomite, etc.). Membrane material is a new type of material, which has the function of selective filtration and separation. The difference between membrane filtration separation and traditional filtration is that the accuracy of membrane materials is often at the micron level and below. When there is a certain driving force on both sides of the membrane (such as pressure difference, concentration difference, potential difference, etc.), the raw material side components selectively pass through the membrane, so as to achieve the effects of filtration, separation, purification and concentration.

According to the "Analysis of Development Trend of China's Industrial Filtration Industry and Forecast Report on Future Investment (2023-2030)" released by Guanyan Report Network, the upstream of the industrial filtration industry is chemical industries such as filter substrates and sealing fittings, as well as metal products industries such as metal plates, profiles, equipment internal parts and electric instrument valves. Downstream is mainly used in lithium electricity, wind power, oil and gas chemical industry, food and beverage, automobiles, semiconductors and other fields.

2, industrial filtration industry market size analysis.

Industrial filtration refers to the filtration process in the industrial manufacturing process through filtration separation and purification technology to improve the cleanliness of industrial fluids to produce more high quality products. Due to the continuous development of industrial scale, product quality standards and environmental protection requirements, the global industrial filtration industry is still in the growth stage and has broad prospects for development. According to the data, the market size of the global industrial filtration industry will reach 32.779 billion billion US dollars in 2022, and the market size is expected to reach 46.551 billion billion US dollars in 2028, with a compound growth rate of 6.02 from 2022 to 2028.

In the Chinese market, the overall technical level of China's industrial filtration industry is not high, the market concentration is low, and there is a certain gap compared with the advanced level of foreign countries. According to relevant data, the market size of China's industrial filtration industry will reach US $10.219 billion in 2022, and the market size is expected to reach US $16.106 billion in 2028, with a compound growth rate of 7.88 from 2022 to 2028.

3, industrial filtration industry downstream application field market scale analysis.

(1) Lithium-electric copper foil field

Copper foil is the mainstream material of lithium battery negative current collector, the quality of copper foil (purity, thinness, etc.) affect the core performance of lithium battery (quality, energy density, resistance), through the use of filtration and separation technology, can improve the quality of copper foil, and then improve the performance of lithium battery, lithium battery can achieve better energy density.

In recent years, with the rapid development of downstream markets such as new energy vehicles, energy storage, 3C digital, small power, and power tools, the market demand for lithium-ion copper foil has increased. According to the data, China's lithium battery copper foil shipments in 2022 were 420000 tons, an increase of 50% year-on-year, accounting for 75% of global lithium battery copper foil shipments.

(2) Nuclear power field

Spent fuel treatment in nuclear power reactors is a key link in the nuclear power industry. Spent fuel produced by nuclear power plants is generally stored in the storage tank of nuclear power plants for 5-10 years, and then transported to the spent fuel reprocessing plant for resource treatment. In the process of spent fuel resource treatment, filtration and separation technology can be used to realize green production. According to data from the China Nuclear Energy Industry Association, China has 54 commercial nuclear power units with a total installed capacity of 55.53 million kilowatts, an increase of 4.3 percent over the same period last year, ranking third in the world; China has 24 nuclear power units under construction, with a total installed capacity of 26.81GW, and the scale of nuclear power units under construction continues to rank first in the world.

(3) Pan-semiconductor field

The pan-semiconductor industry is a general term for integrated circuits, display panels, photovoltaics, etc. In recent years, driven by policy support and technological innovation and change, the scale of China's pan-semiconductor industry has expanded rapidly, and the demand for electronic special gases and wet electronic chemicals has also gradually increased, driving the demand for related filtration products, especially in the field of integrated circuits, which requires extremely high purity of electronic special gases and wet chemicals and strict performance requirements for filtration products. According to the National Bureau of Statistics, China's integrated circuit production reached 359.435 billion pieces in 2021, up 37.49 percent year-on-year, and 324.19 billion pieces of integrated circuit production in 2022, down 9.81 percent year-on-year.

4. Development trend of industrial filtration industry

At present, international manufacturers occupy the middle and high-end market of filter materials, and the added value of products is high. Under the background of national policy support, in the future, domestic filter material enterprises with core technology and R & D advantages will gradually occupy a larger market share by relying on product technology advantages and localization advantages. Such as domestic low-end e-PTFE film thickness uniformity, bubble point uniformity, etc. are poor and the nominal aperture is difficult to reach 0.1μm and below, while foreign similar high-end e-PTFE film prices are higher, unstable supply, domestic enterprises through the introduction of high-end e-PTFE film, can obtain a larger market share. In addition, high-performance filter materials also include PES, ceramic membranes, metal membranes, etc. These filter materials are the key development directions in the future.
