Lewatit® NM 91 is a premium grade, gel type, high capacity, high purity mixed ion exchange resin prepared with a unique volumetric ration of 55% gel, strong acid resin, and 45% gel, Type 1 strong base anion resin. It is a mixture of standard cross-linkage gel type cation exchange resin in the hydrogen (H) for, and a gel type, strong base anion exchanger resin in the hydroxide (OH) form. The mixed resin is prepared from component resins which have been manufactured with a high degree of purity and conversion to the H/OH form. Lewatit NM 91 is characterized by high cation exchange capacity. It is supplied pre-mixed as spherical beads in a heterodisperse particle distribution in the fully swollen bead form Lewatit NM 91 is specially designed for water demineralization applications with high Alkalinity to FMA rations, where complete removal or silica and CO2 is not required. The resin mixture is designed for non-regenerable application. It also can be used for demineralization of service water, waste water and water recovery in small units and once-through cartridges (DI water) for: - EDM recycling
- alkaline feed demineralization
- laboratories and photo laboratories
- household appliances (e.g. steam irons, air humidifier)
- small industrial plants (e.g. refilling of starter batteries or coolant circuits)
- water for watering
