ResinTech SBMP1-OH is a type 1 macroporous strong base anion resin in hydroxide form. It has higher crosslinking than gel anion resins, greater physical, thermal, and oxidative strength, and is optimized for waters that punish other anion resins. SBMP1-OH is intended for high flow rate and high temperature polishing applications, and for other applications that require the highest possible physical strength and chemical durability.
