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.

Carboxy Methyl Cellulose CMC Sodium is one kind of poly anionic cellulose ether which has good solubility in both hot and cold water for oil drilling.

Poly Anionic Cellulose (PAC) has a wide range of application and can be applied to all application fields of CMC.
