we are professional ! pls see below details CMC LV / HV 65% - 70% PAC LV / HV 95% 98% OEM is accepted with special specs .
Usage:
Polyanionic Cellulose (PAC) -HV is for water-based drilling fluids, which can effectively reduces the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environment.
Polyanionic Cellulose (PAC) -LV is for use in solids-laden, water-based drilling fluids, which can effectively reduces the filtration rate of many water-based drilling fluids, without causing significant increases in viscosity or gel strength.
