Product Description

Zeolite is a group of natural or synthetic hydrated aluminosilicate minerals which contain alkali and alkaline metals. It is characterized by a framework structure that encloses interconnected cavities occupied by ion-exchangeable large metal cations and water molecules permitting reversible dehydration. Zeolite is recommended in detergent manufacturing for the applications of the removal of hardness and heavy metal ions and neutralization of acid waters, high cation exchange, gas absorption and water retention capabilities. Their large effective surface area gives them superior adsorptive qualities.
