Molecular sieves, marketed under the trademark Siliporite®, make up a comprehensive portfolio of adsorption agents for the following sectors:

Arkema’s experts in this area are available in Europe, the United States, Asia and the Middle East. R&D is located in Lacq, France, close to one of the largest sour gas deposits in Europe. This research center runs a number of pilot plants replicating our customers’ own processes, which enables us to fine-tune our products based on specific applications. 


Arkema operates two molecular sieves production plants, one in Honfleur, France, and the other in Inowroclaw, Poland. In 2017, a new plant opened on the French site, financed by a 60 million euro investment, which will enable the Group to support its customers’ growth in the refining and petrochemicals sector, in particular in Asia and the Middle East.
