Molecular sieves Selective results

We produce speciality zeolite materials for highly selective substance separations or thermochemical applications under the brand name Köstrolith^®. Satisfying our customers’ needs is consistently at the heart of everything we do.

We supply all market-relevant zeolitic molecular sieves as hydrophilic granules and are one of the few suppliers to also offer these products without a binder component. With pore sizes and surface properties adjusted according to each customer’s individual requirements, the optimum results are guaranteed for each application.

At CWK, the quality and cost of production are of utmost importance. With the development expertise and optimised plants which are at our disposal, we are able to implement your specific requirements quickly and with a high degree of flexibility.
