Samyang Corporation Unveils Next-Generation Ion-Exchange Resin for Semiconductor Ultrapure Water, Cuts Sodium by 94%

Develops high-purity materials as HBM and advanced process nodes proliferate
Also unveils AI-based integrated water-treatment design program

Samyang Corporation is accelerating the localization of materials for semiconductor ultrapure water production by unveiling a next-generation ion-exchange resin for semiconductors with 94% less sodium than its existing products.

Samyang Corporation said on October 29 that it held “TRILITE DAY 2026” on October 28 at its headquarters in Jongno-gu, Seoul, inviting around 70 executives and employees from water-treatment customer companies.

Unveiled at the event, Maxpurity UPRM500U features 94% less residual sodium in the resin than the existing UPRM400U product. It also has reduced levels of eight metals, including iron, calcium and magnesium, to increase the purity of ultrapure water.

Ultrapure water is water from which impurities such as ions, organic matter and particles have been removed to an extreme degree. It is used in processes such as cleaning semiconductor wafers. As semiconductor circuit line widths shrink to 2 nanometers (nm) or less, even trace impurities can cause product defects, making water quality management increasingly important.

Ion-exchange resin is a key material used in the final purification stage of the ultrapure water production process. Since no further process to remove ions follows this stage, the purity of the ion-exchange resin itself directly affects the quality of the finished ultrapure water.

Samyang Corporation also plans to build a dataset that will enable it to quantitatively predict the amount of metals leached from ion-exchange resin, based on management standards covering 24 metals and ions.

The event also featured New TriAngle, an AI-based integrated water-treatment design program. Users enter parameters such as treatment flow rate, raw water conditions and operating time, and the AI analyzes ion-exchange resin, reverse osmosis (RO) and electrodeionization (EDI) processes together to produce an optimal water-treatment process flow diagram in under one minute. Samyang Corporation said it was the first company in the world to develop an integrated design program of this kind.

The company also introduced Maxcapacity MA-10E, a high-capacity anion-exchange resin with around 15% greater ion-exchange capacity than its existing products, and provided an update on the development of high-purity ion-exchange resin for condensate polishing systems at nuclear power plants.

“Now that we have reached the stage of managing the purity of each individual ion-exchange resin bead for semiconductor ultrapure water, we will accelerate product commercialization and contribute to localizing materials for semiconductor ultrapure water production,” said Cho Youngdo, head of Samyang Corporation’s WS PU. “New TriAngle will shorten the time needed to design water-treatment systems and help us respond more quickly to customer needs.”
