Carboxymethylcellulose (CMC)

carboxymethyl cellulose (CMC) is a highly pure and fine cellulose ether, made from cotton linter. The appearance of 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, and can 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 characteristics 2) It can form high quality slurry cake which is strong and flexible 3) 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 well 4) It effectively controls the rheology of slurry with good non-newtonian fluid performance 5) 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 structure As a leading supplier of CMC in China, we also can supply toothpaste grade CMC, food additive grade CMC, ceramics grade CMC as per customers' requirements.
