XR-UPW-501 Grade B · Specialty Series Proprietary Application Media

UPW-Ultra™ Final Polishing Mixed Bed

Wafer-grade final polishing mixed bed with extremely low leachables.

Final polishing mixed-bed medium for semiconductor and photovoltaic UPW systems. Uniform-particle gel cation/anion resins blended in optimized ratio, focused on controlling resin leachables and rinse-down time—for trace-ion and TOC control at the UPW system outlet.
