Poly Anionic Cellulose PAC
PAC(Poly anioniccellulose)
Poly anioniccellulose (Poly anionic cellulose) is abbreviated as PAC, which is a water-soluble cellulose ether derivative obtained by chemical modification of natural cellulose. It is an important water-soluble cellulose ether. Usually its sodium salt is widely used in oil drilling. Especially brine wells and offshore oil wells.
