Resinex™ MX-21Mixed Bed Resin-Mixed Bed Ion Exchange Resin/Mixed Bed Deionizers
Resinex™ MX-21 is a ready-to-use mixed bed resin specially designed for the production of fully demineralised water, e.g.
circulating water in EDM applications. The product is made up of a 1:1,5 volumetric ratio of Resinex™ K-8 and Resinex™
A-4 to offer a very low conductivity in the outlet during operation. The high operating capacity offers an economic advantage
and the type 1 functional group in the anionic compound guarantees a high purity, silica free water.
