Commodity Name: Polyanionic Cellulose;Sodium Carboxymethyl Cellulose
CAS No.: 【9004-32-4】
Synonyms/Type: PAC LV;PAC R;PAC HV;CMC HV;CMC LV
HS Code: 39123100
Application: Oil Drilling Industry
PAC(Polyanionic cellulose) and CMC (Carboxymethyl cellulose) are used in oil drilling fluids and completion fluids. In drilling fluids, it works as viscosifier, flowing controller and filtration reducer, with strong suspending capability, high ability of carrying crumbs, and the function of cleaning drilling crumbs, stabilizing of well wall, preventing the mud from flowing away, protecting drilling bit and reducing the thickness of mud cake, but while in the completion fluids, it functions to control the fluid viscosity, suspend the heavy objects, bring the filler and avoid the fluids loss. It also can replace guar gum in fracturing fluids.
