Product introduction

Polyanionic Cellulose referred to as PAC, is made from natural cellulose by chemical modification and the obtained water-soluble cellulose ether derivatives, is an important water-soluble cellulose ether, its sodium salt is usually applied. Polyanionic Cellulose has good heat stability and salt tolerance, anti-bacterial and strong. The product is prepared with a good drop of fluid mud water loss, inhibition, higher temperature resistance. Widely used in oil drilling, especially offshore oil drilling wells and salt water.
