Croscarmellose sodium
Description
Croscarmellose sodium CMC LV/HV/MV is important cellulose ethers, chemically modified natural fibers are obtained after a good water-soluble polyamines compound, soluble in cold water. It has emulsifying agent, a solid dispersion, and non-perishable, physiologically harmless unusual and extremely valuable comprehensive physical and chemical properties.
Croscarmellose sodium CMC LV/HV/MV can be widely used in petroleum drilling, having good water loss control capability.
