About
Sunresin New Materials Co., Ltd. (SZSE: 300487), headquartered in Xi'an, China, is a globally top-three ion exchange resin manufacturer with annual output exceeding 100,000 cubic meters of resin and delivery of over 200 system equipment sets per year. Founded in 2001, the company operates an integrated materials-plus-equipment model offering complete separation solutions from process design through equipment delivery. Sunresin produces a comprehensive resin portfolio including strong acid cation, strong base anion, weak acid cation, weak base anion, mixed bed, and powder resins, alongside specialty products such as chelating resins for metals recovery, adsorbent resins for food processing, catalyst resins replacing liquid acids, enzyme carriers for immobilization, chromatographic media for bioseparation, and SPPS carriers for peptide synthesis. The company's proprietary Sepsolut® valve-array and Puritech® multi-channel valve technologies enable continuous Simulated Moving Bed separation systems. Sunresin's Direct Lithium Extraction program has secured nine commercial contracts totaling 73,000 tpa lithium carbonate equivalent. Additional offerings include compact skid-mounted units, mobile sorption modules for gold extraction, and PFAS removal resins certified to NSF/ANSI/CAN 61 standards. Application sectors encompass drinking water treatment (arsenic, boron removal), industrial water (softening, demineralization, ultrapure, condensate polishing), wastewater reuse, hydrometallurgy (lithium, copper, nickel, gold), food and beverage processing, biopharmaceutical purification, chemical catalysis, and VOCs treatment. Production bases span Xi'an, Weinan, Hebi, Belgium, and Argentina.
