The company’s core business involves the research,development,production, and sale of adsorption and separation materials, as well as integrated flexible solutions that combine supporting system equipment and adsorption and separation technologies centered around these materials.

The Company’s business can be categorized into three major segments based on product type:adsorption separation materials,system equipment,and technical services.According to the 2025 interim report,its revenue breakdown is as follows: adsorption materials accounted for 80.71%,system equipment for 14.70%,technical services for 2.95%,and other revenue for 1.63%.

The company’s products and services are applied across multiple downstream sectors, including metal resources, life sciences, water treatment and ultrapure water,food processing, energy conservation and environmental protection, and chemical and industrial catalysis.

In the metal resources sector,the company is involved in the lithium industry chain.As of the 2025 interim report,it has completed or is currently executing a total of 12 industrial-scale lithium extraction projects from salt lakes, with a combined designed production capacity of nearly 100,000 metric tons of lithium carbonate and lithium hydroxide.In the life sciences sector,the company operates a business in peptide solid-phase synthesis carriers and is one of the suppliers of GLP-1 drugs (produced via solid-phase synthesis).Its small nucleic acid carrier products have been used in dozens of clinical-stage projects,and the company plans to invest in the construction of a high-end life sciences materials industrial park.

The company’s core business involves the research,development,production, and sale of adsorption and separation materials, as well as integrated flexible solutions that combine these materials with supporting systems and adsorption and separation technologies.

The company produces over 100 varieties of adsorption and separation materials across more than 30 product series, including ion exchange resins, macroporous adsorption resins,water treatment resins,chelating resins,resins for pharmaceutical use, resins for plant extraction, resins for food applications,and wastewater treatment resins.

The company possesses multiple core technologies,including lithium extraction adsorption technology for salt lakes,jet-spray particle size uniformization technology(used in the production of ultra-pure water resins),and patented boron removal resin treatment technology.

The company provides integrated system equipment centered on specialty adsorption and separation materials,including valve-array continuous ion exchange units, multi-port valve units, simulated moving bed continuous chromatography systems,and high-throughput industrial preparative chromatography systems.

The products are widely used in industrial sectors such as food,pharmaceutical, plant extraction,ion-exchange membrane caustic soda production,environmental protection,chemical catalysis,hydrometallurgy,and water treatment,with a market presence spanning over 100 countries worldwide.

Based on downstream application scenarios,the company has established six major business segments: metal resources, life sciences, water treatment and ultrapure water,food processing,energy conservation and environmental protection, and chemical and industrial catalysis.

In the metal resources sector, the company’s technologies are applied to lithium extraction from salt lakes, nickel extraction from laterite deposits,cobalt extraction and recovery,vanadium extraction from lignite,and gallium extraction from bauxite leachate.As of the 2025 interim report,a total of 12 industrial-scale lithium extraction projects from salt lakes have been completed or are currently underway,with a combined production capacity of nearly 100,000 metric tons of lithium carbonate/lithium hydroxide.

In the life sciences sector,the company offers a range of products,including chromatography media,chromatography resins,microcarriers,solid-phase peptide synthesis carriers,solid-phase nucleic acid synthesis carriers,magnetic microspheres, adsorption materials for Western pharmaceutical,and immobilized enzyme carriers. Among these,the solid-phase peptide synthesis carrier business has experienced rapid growth and has become a key supplier for GLP-1 drugs (produced via solid-phase synthesis).

In the water treatment and ultrapure water sector,the company has achieved a breakthrough in jet-milling technology for particle size uniformity, enabling the large-scale production of uniformly sized white spheres.It has developed multiple high-end product lines, including ultrapure water and chromatography-grade products, which are used in nuclear power, semiconductor, and display panel manufacturing.
