Polyanionic cellulose and carboxymethyl cellulose (CMC) are both cellulose derivatives that are widely used as thickeners in various industries. While they share some similarities, there are also key differences between the two that make them suitable for different applications.Polyanionic cellulose

Polyanionic cellulose(PAC) is white or light yellowish powder or granular.It is easily soluble in cold or hot water,.The PAC exhibits high performance in various salt resistance,including calcium,magnesium-resistance.It can reduce filtration loss. It can be used in all water based drilling fluids, e.g. salt water based,seawater based and saturated-brine drilling fluids.It can reduce filtration very well.
