Molecular Sieve

Stream Peak’s Molecular Sieve is made of crystalline aluminosilicate with SiO2:AI2O2 in the ratio of 2:1. It is also known as zeolite or mol sieve. The desiccant is formed from the extensive cross-linking between AIO4 and SiO4 tetrahedra, resulting in the different sizes of pore openings found, determining the type of Molecular Sieves. Molecular Sieves reduce humidity levels or dehydrate, purify and separate selective gas and liquid substances. They are also able to absorb up to 22% of their weight. 

How do Molecular Sieves work? 

The customised pore openings of the Molecular Sieve allow the separation of specific molecules from one another by absorbing smaller than the diameter of the pore openings and excluding the rest. Hence, enabling them to dehydrate, purify and separate selective gas and liquid substances.  

Capable of absorbing up to 22% of its weight, Molecular Sieves are also commonly used in filtration systems or sachets to reduce humidity levels. The desiccant can be used in temperatures up to 300°C, making it suitable for machinery applications. The product applications of each type of Molecular Sieve differ due to their different pore sizes, making the nature of Molecular Sieves very robust as they can be used for multiple purposes. Molecular Sieves can also be regenerated at high temperatures when exposed to moisture over a long period. To restore the absorbent to full capacity, heat it to an optimal temperature of 130°C – 250°C. However, this temperature differs for each type of Molecular Sieves. Here in Stream Peak, we supply the Molecular Sieves in four different types, providing users with high absorption capacity, mechanical strength, and low attrition loss. Although each type of Molecular Sieve has specific properties and applications, it retains its primary water absorption function.
