As swelling clay, Bentonite has the ability to absorb large quantities of water, which increases its volume by up to a factor of eight. Bentonite swelling property is used as an advantage in drilling mud and groundwater sealants. These give the clay a very large total surface area, making Bentonite a valuable adsorbent. We provide all variants of Bentonite, Bentonite 9, Bentonite 10, Bentonite 11, OCMA Bentontie.
