All kinds of? Natural Calcium Bentonite/ Sodium Bentonite powder in China?
?
?Brief introduction:
YH series bentonite thickening and rheological additive is a kind of natural aluminum magnesium silicate, hydrophilic and high purity (modified) Montmorillonite is the main ingredients. The colloid performance is similar to Veegum and Magnabrite that produced by FINDBEER Company, American. This product is widely used in water based coating, emulsion paint. medicament, toothpaste, cosmetic, rubber, papermaking and so on. it act as floatability, thixotropic agent, stabilizer, thickening agent. In pharmacy, it is used as medical adhesives, disintegrating agent and stabilizer. In founding paint and various ceramics colorful paint, it is used as floatability and thixotropic agent; some performance of this serial is superior to use the CMC, HEC respectively.

The main character of six specification YH-A/B/C/D/E/EV as following:
- Strong thixotropic, high shear with low viscosity; low shear with high viscosity, the index of thixotropy reach to 6.0.
- Extensive PH range of application: it will go into effect during PH5-12.
- Easy dispersivity: need not pre gel and active agent.
- Stability: fine biochemical stability, and fine heat stability.
- Mutual solubility: easy to dissolve in the alcohols and high polar solvent (glycerin, sorbitol).
- Economical efficiency: it will reduce the cost when use product alone, also, mix using with the celluose aether, crylic acid will improve the rheological property, lower the cost at the same time!
