HIGH SILICA ZEOLITE

ABOUT HIGH SILICA ZEOLITE

When the ratio of SiO2 in molecular sieve M2/nO.Al2O3.xSiO2.yH2O is increased to High Silica Zeolite, the proportion of metal cations present in the molecular sieve crystal lattice is decreased.
This causes the affinity of high silica zeolite towards polar substances such as water is weakened and becomes more strongly adsorb nonpolar substance.

Because of these adsorption properties, hydrophobic molecular sieve called High Silica Zeolite preferentially adsorbs Volatile Organic Compounds (VOC) and Odor components rather than moisture in the atmosphere, hence it can be utilized for VOC removal and deodorant applications.

 ※ Adsorption volume may change depending on the atmosphere condition (humidity, temperature, etc.), therefore this data is for reference only. We recommend to actually evaluate the adsorbents.

In addition, we can make prototype zeolite according to customer’s request.
