Samyang aims to significantly expand sales of ion exchange resins used in semiconductor ultrapure water (UPW), targeting annual revenue of 120 billion won within the next two to three years. The company expects rising investment in artificial intelligence (AI) data centers and the resulting expansion of semiconductor fabrication plants to support the goal. It also plans to increase the share of high-value products—including those for semiconductors, nuclear power and chromatography—to 60% of total ion exchange resin sales.
According to industry sources on July 9, Samyang has begun supplying its high-value TRILITE UPRM300U and TRILITE UPRM400U ion exchange resins for UPW systems to major semiconductor manufacturers in South Korea. The products passed Samsung Electronics' qualification tests in 2022. The company is now expanding its global customer base and increasing adoption across additional production lines.
Its customer portfolio includes Samsung Electronics, SK hynix, Amkor Technology, Chengdu Gaozhen Technology Co., Ltd. (CHJS) and United Microelectronics Corp. (UMC) in the semiconductor sector. It has also expanded supplies to display manufacturers including Samsung Display, LG Display, Visionox, Tianma and HKC, as well as to Mitsubishi Chemical and Dongwoo Fine-Chem.

Samyang is South Korea's only domestic producer of ion exchange resins. After entering a market previously dependent on imports, the company has secured a 38% share of the domestic market. It began production in 1976 through a technology partnership with Mitsubishi Chemical before developing its own proprietary manufacturing technology. In 2011, Samyang became the first South Korean company to independently develop ion exchange resins for semiconductor UPW applications.
More recently, the company expanded its portfolio into ion exchange resins for semiconductor final polishers. These products remove residual ions and metallic impurities during the final stage of UPW production. Ultrapure water is used throughout semiconductor manufacturing, including wafer polishing, dicing, post-etch cleaning and ion implantation. Because even trace levels of contamination can reduce manufacturing yield, the resins must deliver high resistivity, low total organic carbon (TOC) levels and extremely low metal ion leaching.
Samyang's ion exchange resin business has recorded annual revenue growth of approximately 10% every year from 2021 through 2025. The company plans to increase the proportion of high-value products from 50% in 2024 to 60%. In the first quarter of this year, its chemical business, including ion exchange resins, generated revenue of 265.2 billion won, accounting for 42.7% of total company sales.
A key competitive advantage is Samyang's homogeneous ion exchange resin manufacturing technology. Conventional ion exchange resins contain particles of varying sizes, resulting in inconsistent ion exchange efficiency and pressure loss. Homogeneous resins feature uniformly controlled particle size and structure, enabling stable UPW quality required for semiconductor, display, nuclear power and biotechnology manufacturing. Globally, only Samyang, Mitsubishi Chemical, DuPont and LANXESS possess technology capable of producing homogeneous ion exchange resins with a uniformity coefficient (U.C.) of 1.1.
Production is split between facilities in Gunsan and Ulsan. Samyang Fine Technology, a 50:50 joint venture established with Mitsubishi Chemical in 2016 in Gunsan, operates one of Asia's largest production bases for homogeneous ion exchange resins. The plant manufactures homogeneous resin materials used in semiconductor UPW systems, which are then transported to Samyang's Ulsan facility for cleaning, classification, blending and post-processing into finished high-value ion exchange resins.
The outlook for the ion exchange resin market is closely tied to rising demand for semiconductor UPW. According to market research cited by the company, the global UPW market is expected to grow from 46.5 trillion won in 2025 to 59 trillion won by 2030, while the South Korean market is estimated at 2.5 trillion won. The global ion exchange resin market is projected to expand from 3.3 trillion won in 2025 to 5.9 trillion won by 2035. Samyang competes globally with DuPont, LANXESS and Purolite.
"Ion exchange resins for semiconductor ultrapure water represent far more than sales growth. They are a significant achievement in localizing a critical material and strengthening supply chain resilience," a Samyang official said. "We will continue enhancing our products to expand our market share among advanced industrial customers in South Korea and overseas while further strengthening our premium product portfolio."
