Bentonite Clay

Product Description

Character: The product is yellowish powder. It has good viscosity, hydrophilicity, cation exchange capacity, refractory and plasticity.

The Bentonite is artificial sodium Bentonite and is welcomed for its good reuse character and high hydrothermal strength. Due to its excellent plasticity, it can prevent casting from collapsing and blockage. Because it is easy to mould and has high intensity, it can be used for casting wet or dry models in metallurgy. It is preferred for bond in precision casting.
