Sunresin expands PFAS resin output to serve stricter water rules

Sunresin New Materials Co. Ltd. says it is scaling production of its SEPLITE® LSI 106G ion exchange resin as utilities and industrial sites race to meet tighter PFAS limits in drinking water. The company is also highlighting field performance, certifications, and global support capacity for large-scale remediation projects.

Why it matters: - PFAS limits in public drinking water are tightening worldwide, including rules from the U.S. Environmental Protection Agency and European health organizations. - Utilities and industrial operators need treatment media that can handle parts-per-trillion targets, short-chain PFAS, and difficult water chemistries. - Sunresin is positioning its PFAS resin business to meet that demand at industrial scale.

What happened: - Sunresin New Materials Co. Ltd. expanded manufacturing capacity for advanced PFAS removal ion exchange resin. - The company says its total annual resin production capacity now reaches 100,000 cubic meters. - Sunresin is promoting SEPLITE® LSI 106G as a specialized strong base anion exchange resin for drinking water and remediation projects. - The company directs readers to its website for more technical specifications and product details: official website.

The details: - SEPLITE® LSI 106G uses a gel-type crosslinked polystyrene copolymer matrix with Type I quaternary ammonium functional groups. - The resin removes PFAS through ionic attraction and hydrophobic interaction with fluorinated carbon chains. - Sunresin says the material can reduce contaminants from microgram levels to non-detectable parts-per-trillion levels. - Compared with standard strong base anion resins, the resin shows about 30% higher operating capacity. - Rapid adsorption kinetics allow shorter empty bed contact times, which can reduce vessel size and capital cost. - The resin is designed for high osmotic and mechanical stability to limit bead attrition and pressure drop under high-flow conditions. - Independent testing bodies have verified the resin’s performance, including NSF/ANSI 61 and Water Quality Association certifications for potable water use. - Production is centered at automated facilities in Gaoling and Pucheng. - Manufacturing controls monitor polymerization, functionalization, and post-treatment washing. - More than 95% of resin beads are maintained within a 0.35 to 1.25 millimeter range. - Each batch is screened for exchange capacity, moisture retention, and kinetic performance before packaging. - The company also offers modular skid systems, custom vessel fabrication, and process optimization consulting. - Sunresin says it has direct European warehousing and technical support in Düsseldorf, Germany.

Between the lines: - The pitch is not just about resin chemistry. It is about supply certainty, certification, and project execution for utilities facing compliance deadlines. - Sunresin is tying product performance to system design, suggesting the company wants a bigger role in full treatment deployments rather than only media sales. - The emphasis on short-chain PFAS reflects a growing pain point, since these compounds are harder to remove with conventional media.

What's next: - Utilities, contractors, and remediation teams are likely to keep seeking higher-capacity media as PFAS limits tighten. - Sunresin is aiming to supply those projects with larger output, regional support, and equipment integration. - The company indicates it will continue pairing resin sales with engineering support for municipal and industrial deployments.

The bottom line: - Sunresin is scaling both production and technical support to compete in a PFAS treatment market where compliance, capacity, and supply reliability are becoming decisive.
