Polyanionic Cellulose (PAC)


 Molecular Formular: [C6H7O2(OH)2CH2COONa]n




Polyanionic Cellulose (PAC) (Polyanionic Cellulose) is a kind of nonionic cellulose ether featured the properties of high purity, high DS, particularly high viscosity or low viscosity. These products are demi-natural polymer additive, thickening agent, filtrate reducer. Polyanionic Cellulose (PAC) is an indispensable product for drilling mud making.


Polyanionic Cellulose (PAC) is high purity product; the water solution of this white powder is transparent and viscid. As water-soluble polymer, it dissolves immediately in cold/hot water and can be used as a thickening agent, rheology controller, bond, stabilizer, colloid protector, suspending agent, and filtrate reducer.


Polyanionic Cellulose (PAC) is a good drilling mud additive and also an important material for confecting well liquid, a high mud volume product that featured high acid-resistance and salt-resistance ability. Polyanionic Cellulose (PAC) is a good filtrate reducer with the capacity of  increasing  viscosity  and  anti-high  temperature  (150°C)  in  the  freshwater,  seawater,  or  even  saturated  brine  well-completion liquid. Polyanionic Cellulose (PAC) is suitable for confecting the completion fluid with these 3 kinds of water above.
