Paper-making grade CMC

  1.Sodium Carboxymethyl Cellulose(CMC) for Papper-Making Industry

  Sodium Carboxymethyl Cellulose is widely used in papper-making industry.CMC is a high-efficiency paper-making auxiliary, and features good moisture retention, dispersibility.

  Sodium Carboxymethyl Cellulose for Paper Making Industry

  Sodium Carboxymethyl Cellulose is used in paper making industry as paper sizing agent, it can obvious increase the dry intensity wet strength, oil resistance, ink absorbance and water resistance of the paper.

  2.Commodity Name: Sodium Carboxymethyl cellulose

  CAS No.: 【9004-32-4】

  Molecular formula :[C6H7O2(OH)2OCH2COONa]n

  Synonyms: Carboxymethyl Cellulose, Carboxy Methyl Cellulose, CMC, Sodium CMC, Na-CMC
