CMC,namely,Carboxy Methyl Cellulose Sodium, is anion-type linear substance with high molecular,CMC has a molecular structure:

The formular is:[C6H7O2(OH)2OCH2COONa]n

Pure CMC is of white or milky powder,tasteless,no-toxic , humidty absorbing, flow fiber-like powder.In water,it disolves into apparent,viscous colloid solution,which having out standing and valuable chemical-physical characteristic such as viscosity,water-deserving,inertia,film or mouid formability,emulable sificational dispersion,solid dispersion and disperse stability.All this allows it to be used as iscosizer,binder,lubricant,emulsifier,float aid,sizing agent,medicinal base and biological carrier as anatural cellulose derivative.

"Yuanyuan" CMC has three super-properties:

namely high purity , ,more than 99%,high viscosity,above 3000mpa.s in 2% solution and high substitution,greater than 1.2%.

Acid-resistant:

The FH9,acid-resisting type CMC has a characteristic of well-distributed substitutive groups.Fine performance and effect can be kept for long time in an acid solution with PH>3.2,e.g.The ratio of acid to viscosity≥0.9.

Anti-salt:

Our CMC and it's derivative,polyanionic cellulose(PAC) would be keep no decrease for its viscosity,even in sea water or the like,e.g.The ratio of salt to viscosity SVR not less than 1.0.It used widely in sea petroleum recover.
