Molecular Sieve

Molecular Sieve Overview

Molecular sieve also known as synthetic zeolite. It is moisture adsorbent with high strength, heat resistance and various shapes and sizes to answer numerous applications.

We are expanding many new applications in drying, refining and separation processes in industries such as oil refining and petrochemical. SDK group has been manufacturing and selling molecular sieves for more than 50 years, and providing excellent products to a wide range of industries.

Based on our own technology, we do provide proposal and consultation about the selection of adsorbents, the most suitable grade. Also, we could give suggestion regarding the design of adsorption facilities.
