Bentonit API stark in USA benötigt.

[Productinformation] Wechoosethehighqualitybentonite.After the purification, modification and processing, then the bentonite for drilling mud forms. We can produce the bentonite for drilling well meeting European standards of OCMA gradeand the United States standards of API grade. [Product Usage] Bentonite has a good expansion after mixed with water and has a good colloidal nature which can increase the viscosity of suspension in the drilling mud. Besides,Bentonite for drilling wells can increase the lubrication of drilling, clean the debris during drilling and also can be used as rig-freeing agent. On account of this special character, bentonite for drilling wells is widely used in comples geological formation drilling.
