CMC and PAC( Polyanionic Cellulose ) can be widely used in Oil drilling, haveing good water loss control capability, PAC product is a kind of effective water loss controller and with high mud yield, strong salt resistance and temperature tolerance.
Technical-grade CMC meets Nation standard GB/T5005-20012(API Section 9)
