Since its founding in 2001, Sunresin has maintained a product positioning of “high technological content” and “high added value.” It has since grown into the largest and most innovative manufacturer in the field of specialty adsorption and separation materials—leading in production capacity, product diversity, application breadth, and industrial breakthroughs. The company currently has an annual resin output of 100,000 cubic meters and delivers over 200 sets of system equipment. In 2024, Sunresin achieved operating revenue of $361million and a net profit of $111 million, with total assets approaching $846million. Today, Sunresin ranks among the top three companies globally in the industry and is recognized as the leading player in Asia.
Headquartered in Sunresin Technology Park in Xi’an High-tech Zone, the company operates production bases and system integration parks for resin manufacturing, equipment fabrication, and hazardous waste recycling across Xi’an, Weinan, Hebi, Belgium, and Argentina.
Sunresin is a nationally recognized “single champion” in manufacturing, a national-level “Little Giant” enterprise for specialization and innovation, and a Second Prize winner of the National Science and Technology Progress Award. In 2023, it was named among Forbes Asia’s Top 200 Best Listed SMEs, the Top 50 Most Valuable Companies on ChiNext, and has consistently ranked among China’s Top 100 Fine Chemical Enterprises.
Focusing on fundamental research in adsorption and separation, Sunresin pioneered the integrated “materials + equipment” solution model to apply its technologies across six major sectors: metals, life sciences, water treatment and ultrapurification, energy conservation and environmental protection, food processing, and chemical catalysis. The company has replaced imported technologies in several areas and industrialized its own innovations in emerging applications, driving technological transformation across multiple industries.
In the metal resources sector, Sunresin’s advanced gallium extraction resins have enabled a comprehensive upgrade in China’s gallium production. In lithium extraction, its integrated “adsorption + membrane” technology has become the industry’s benchmark for extracting lithium from brine. To date, Sunresin has signed lithium extraction projects with a combined lithium salt capacity of nearly 100,000 tons—worth RMB 3 billion in total contract value—spanning Qinghai, Xinjiang, Tibet, as well as Europe, the Americas, and South America. International clients regard Sunresin as a “DLE leader” for its pioneering work in direct lithium extraction from brine. The company has also made significant advances in the large-scale extraction of other rare metals such as nickel, cobalt, uranium, and scandium.
In life sciences, Sunresin was the first in China to develop CPC separation and purification resins, breaking the long-standing dominance of other global suppliers. Its proprietary enzyme carriers have enabled the industrial production of enzymatic 7-ACA, marking a major innovation and contributing to industry upgrading. Its solid-phase synthesis carriers serve as key raw materials for GLP-1-based weight-loss drugs, currently in strong global demand.
In the food industry, Sunresin pioneered the use of adsorption and separation technology in juice quality control, developing a suite of products for decolorization and pesticide residue removal. It has also established deep-processing technologies for extracting fructose, pectin, fruit acids, and polyphenols—helping steer China’s juice industry toward high value-added, resource-efficient production.
In the ultrapure water sector, Sunresin drove significant advances in the production of uniform particle technology, enabling the large-scale production of uniform beads. It has developed multiple high-end resin product lines, including ultrapure water and chromatographic resins, introducing new technologies to nuclear energy, semiconductor, and display panel industries. Today, the company provides uniform particle cation/anion resins and polishing mixed beds, establishing itself as a leading global supplier.
With its focus on high-tech, high-value-added positioning, Sunresin emphasizes core technological innovation, pushes the boundaries of industrial application, and explores interdisciplinary advances. The company continues to expand into new categories and varieties of adsorption materials—using material breakthroughs to drive original technology development and explore emerging, high-potential applications. Sunresin remains committed to advancing adsorption and separation technologies in broader and deeper fields, contributing to the overall progress of the industry.
Since its IPO 10 years ago, Sunresin has completed three rounds of refinancing, each supporting key development milestones. The company has built high-quality production capabilities that have driven growth in both output and sales, laying a strong foundation for becoming a globally recognized brand. Additionally, Sunresin has implemented an equity incentive plan covering over 700 employees, fostering cohesion, innovation, and shared growth. Since its listing, the company has also contributed nearly $139million in taxes and distributed $160 million in cash dividends—underscoring its commitment to corporate social responsibility.
