oil drilling chemical-PAC(Poly-anionic cellulose)

Polyanionic Cellulose(PAC) has good salt resistance, heat resistance and antibacterium. It is widely used in petroleum drilling . In drilling fluid, it works as viscosifier, filtration reducer, and rheology controller; in fixing fluid, it is used to control fluid viscosity, suspend heavy objects, and avoid fluid loss; in fracturing fluid, it is used to carry stuffing and avoid fluid loss.
