ResinTech MB-SP-50 is a 50:50 volumetric mixture of CN8-H (US made black-colored hydrogen form strong acid cation resin) and SBG1P-OH (hydroxide form type 1 porous strong base anion resin). MB-SP-50 is designed for applications where a pH-balanced mixed bed is not required. MB-SP-50 is intended for general purpose deionizing applications, such as spot-free rinsing. MB-SP-50 performs best on high alkalinity waters.
