The Gravex GR 2-5 SG is a premium grade product of sulfonated, styrene-DVB copolymer. It is suitable for use with GR 1-0 US in mixed bed condensate polishing and blowdown demineralizers. It has exceptional hydraulic properties which are ideal for condensate polishing flow rates. It has a strongly acidic macroporous, hydrogen form cation exchange resin for condensates and other applications of high purity. Available in hydrogen or morpholinium ionic forms, it has a high capacity with exceptional physical and chemical integrity and stability. The morpholinium form is particularly useful in PWR steam generator blowdown demineralizers and helps to control the cycle chemistry while maintaining the amine concentration. The macroporous cation offers enhanced sodium performance due to its increased selectivity in the presence of morpholine. Gravex GR 2-5 SG can be used with GR 1-0 US.
