Both American API standard and the European OCMA standard can meet.All your inquiry will get our immediate attention!With carefully selected bentonite of high quality, then through the purification, modification, processing we develop the bentonite for drilling mud, whose quality meet international standards of OCMA and the United States API grade.Product UsageBentonite has high expansionafter meeting water and a good colloidal nature, which can increase the viscosity of suspension in the drilling mudand also can increase the lubrication of drilling, clean the debris during drilling, as well as for the rig-freeing agent.

So it is widely used in complex geological formation drilling.Physical & Chemical Index Index
