Carboxymethyl Cellulose (CMC)

CMC is a highly pure and fine cellulose ether, made from cotton linter. The appearanceof the product is white powder. Its water solution shows high transparency,good rheological property and thixotropy. Oil drilling grade CMC can be used as water-soluble gel for drilling fluids, andcan form artesian well liquor.Features:  1) It has good water-loss controlling ability, especially PAC is highly effective    drop filter-loss agent; even added at low quantity, it can control water loss    at very high level, but does not affect slurry's other characteristics2) It can form high quality slurry cake which is strong and flexible3) It has good temperature resistance and superior anti-salt character; under    certain salt density, it can remain good water-loss capability and certain     rheology, so the viscosity in salt solution is the same as in water, which is    specially suitable for sea misering and deep well4) It effectively controls the rheology of slurry with good non-newtonian fluid    performance5) Moreover, CMC can be used as well fixing liquor to prevent fluid entering     terrane or crack, and also can be used as pressing liquor to control the     loss of fluid into oil well structureAs a leading supplier of CMC in China, we also can supply toothpaste grade CMC, foodadditive grade CMC, ceramics grade CMC as per customers' requirements.
