Polyanionic Cellulose (PAC)

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.

PAC has good properties of salt resistance and temperature resistance, PAC is especially better then CMC and also it have good non-Newtonian fluid, can effectively control the mobility of mud.

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.
