What is PFAS Resin? A Technical Overview
PFAS resin refers to specialized ion exchange resins engineered to selectively capture and remove per- and polyfluoroalkyl substances from contaminated water. Unlike standard water treatment media, PFAS resin features quaternary ammonium functional groups specifically designed to bind the negatively charged head groups of PFAS molecules through ionic attraction.
The best PFAS resin for drinking water applications combines high selectivity with rapid kinetics, enabling treatment systems to achieve parts-per-trillion compliance without the massive footprint required by granular activated carbon systems. Sunresin's SEPLITE® LSI 106G represents the next generation of PFAS resin technology, delivering 30% higher adsorption capacity than conventional strong base anion exchange resins while maintaining full regenerability.
PFAS Resin Molecular Structure
- 1 Matrix: Crosslinked polystyrene copolymer (gel type)
- 2 Functional Group: Quaternary ammonium (Type I strong base)
- 3 Mechanism: Anion exchange + hydrophobic interaction
- 4 Regeneration: 10-12% NaCl brine solution
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent, hazardous chemicals that pose growing health risks through drinking water, surface water, and industrial discharges. Known as "forever chemicals" due to their resistance to degradation, PFAS have been linked to serious health issues including immune suppression, thyroid disorders, liver damage, and reproductive problems—even at extremely low concentrations.

Sunresin’s ion exchange technology offers a high-performance solution for the selective removal of PFAS from both drinking and industrial water.
Our specially engineered anion exchange resins feature quaternary ammonium functional groups that selectively attract and bind negatively charged PFAS molecules—including long-chain compounds like PFOA and PFOS, as well as the increasingly concerning short-chain variants.
Resins designed to target PFAS molecules specifically
Removes PFAS to parts per trillion (ppt) levels
Resins can be regenerated for repeated use
Compared to traditional technologies such as Granular Activated Carbon (GAC) or Reverse Osmosis (RO), ion exchange provides distinct advantages:
Faster PFAS adsorption kinetics than GAC
Higher capacity for both short- and long-chain PFAS
Smaller system footprint, reducing space demands
Longer operational lifespan under low-concentration conditions
Sunresin’s SEPLITE® LSI 106G is a high-performance, gel-type strong base anion resin specifically developed for PFAS and perchlorate removal in drinking water applications.
