“For our ion exchange resins business, we see great potential in numerous future-oriented industries. We intend to make even better use of this potential by optimising our technology,” says Rainier van Roessel. “At the same time, with this investment, we are further strengthening the position of the Leverkusen site as the heart of our production operations in Germany.”

Demand for ion exchange resins is rising, in the battery industry, for example, driven in particular by the trend toward electric vehicles. The metals essential for battery cell production – lithium, nickel and cobalt – can be extracted by means of ion exchange resins.

LANXESS ion exchange resins polymer beads liquid purification technologies

Ion exchange resins are polymer beads that absorb undesirable substances in fluids. Depending on the substance, differently functionalised beads are used.

Possible household applications include, for example, softening water in dishwashers and cartridges in household water filters. Here, ion exchange resins remove undesired calcium and magnesium salts or lead and copper ions from tap water. This improves the quality and taste of the drinking water.

In power plants, the polymer beads are used in the production of highly purified water and steam. Deposits and corrosion can thereby be prevented and efficiency, operational safety and service life increased. Furthermore, ion exchange resins help in removing selected heavy metals, such as mercury and cadmium, and organic pollutants from both groundwater and industrial wastewater.
