Resinex™ A-4 UB is a high purity, premium grade, strongly basic gel-type anion exchange resin type 1, specially designed for achieving very low silica leakage in water demineralisation applications.
The product is a bead type, crosslinked polystyrenedivinylbenzene copolymer resin that offers a good resistance to physical and mechanical breakage and organic fouling.
The selected bead distribution of Resinex™ A-4 UB - very close to monodisperse - is especially adapted for all modern counter-current systems (i.e. Schwebebett, UPCORE,..) and mixed bed systems.
