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.
