Specifications
Paper Making grade sodium carboxymethyl cellulose cmc
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.
CMC is a high-efficiency paper-making auxiliary, and features good moisture retention, dispersibility
Uses: in the mining, oil and gas drilling mud stabilizer; in the textile industry, it can be a substitute starch for sizing warp; in the paper industry, it can be added to paper pulp to increase the strength of oil and finely ground; In the pharmaceutical industry, can be used as creams, ointment base materials.
