AmberLite 62i Inert Resin is a floating, non-functionalized, transparent, amorphous-shaped resin with properties specifically designed for use as an upper layer in up-flow regenerated ion exchange systems, such as UPCORE Packed Bed Systems. This inert resin has a specific gravity lower than water, which ensures it will stay above the ion exchange resin bed. Its self-distributing properties allow it to evenly cover the available cross-sectional area, forming a protective layer that allows dirt and resin fragments to pass through while retaining the resin bed during the compaction/bed-lift step prior to regeneration.
