High viscosity bentonite from Weifang Yaxin Bentonite Factory. Search High Quality High viscosity bentonite Manufacturing and Exporting supplier on Alibaba.Bentonite - Wikipedia,In geology, the term bentonite is applied to a type of claystone composed mostly of montmorillonite. It forms by devitrification of volcanic ash or tuff, typically in a marine environment. This results in a very soft, porous rock that may contain residual crystals of more resistant minerals, and which feels soapy or greasy to the touch. However, in commerce, the term bentonite is used more generally to refer to any swelling clay composed mostly of smectite clay minerals.
