Poly Anionic Cellulose and Sodium Carboxymethyl Cellulose
Our PAC (oil drilling grade) and CMC are advantageous because of their: small usage, high yield; good salt tolerance, anti-bacterial property and
convenient to use; the fluid loss reduction and the viscosity improvement; flowing control and strong suspending capability; environmental friendly, nontoxic, harmless and odorless; and good liquidity, convenient to construction.
