Packing Mall 4A Zeolite
Product Details
Packing Mall 4A zeolite
Product Description
Type 4a has reliable adsorption speed, higher resistance quality, and stronger adsorption, which are enough to enhance product life. Such type of molecular sieve is perfect to remove the moisture from liquids and gases. It is a universal dehydrating agent used in polar and non-polar media. This type of molecular sieve is the perfect desiccant for low inlet, humidity, with the temperature below 30-35% RH.
4A molecular sieves can be available in the form of beads, pellets and powder form.
Chemical Molecular Formula: Na2O . Al2O3 . 2SiO2 . 4.5H2O (SiO2:Al2O3=2)
