Polyfluoroalkyl substances, known as PFAS, are man-made chemicals found in everyday items such as non-stick, fast-food wrappers, stain-resistant fabrics, non-stick cookware, firefighting foams, and the manufacturing of certain papers.
PFOS-891DQ is a product designed with high selectivity for perfluoroalkyl substances. The product with various degrees of porosity provides dual removal mechanisms by both ion exchange and adsorption and deliveries excellent high operating capacity and kinetics.
Through the treatment operation the resin will effectively remove both the long and short chain PFAS such as PFOA, PFOS.

PFOS-D891DQ resin is insoluble in dilute or moderately concentrated acids, alkalies, and in all common solvents. However, exposure to significant amounts of free chlorine, “hypochlorite” ions, or other strong oxidizing agents over long periods of time will eventually break down the crosslinking.
This will tend to increase the moisture retention of the resin, decreasing its mechanical strength, as well as generating small amounts of extractable breakdown products. It is thermally stable to higher than 75 C (170 F) in the chloride form.
