설명
Bentonite, sodium form is used as a suspending agent, a gel binder, a filler in ceramics and a catalyst support.Sodium bentonite is widely utilized as a natural sealant in recreational ponds, dairy and sewage lagoons and city landfills. Due to its colloidal property, it is employed in drilling mud for oil and gas wells. Due to its swelling property, it provides a self-sealing low permeability barrier. It combines with polymers and enhances the surface modifications, which are used for rheological or sealing performance in geo-environmental applications.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
