Product Description
Sodium Carboxymethyl Cellulose (CMC) is non-ionic cellulose ether made from natural cotton fiber under series of chemical processing. It's odorless, tasteless and non-toxic white powder, can be dissolved in cold water to form a transparent viscous solution with the properties of thickening, binding, dispersing, emulsifying, film coating, suspending, absorbing, gelling, water retention and colloid protection.

Paper Grade CMC
Sodium carboxymethyl cellulose (CMC) is an efficient papermaking additive that can be used in pigment coating, pulp
addition,surface gluing and other processes. It has good water retention, dispersion and excellent shear thinning properties.
CMC can be used as papersurface smoothing agent and sizing agent in the paper industry to make the paper have high density, good ink penetration resistance, high wax collection and smoothness.
Adding 0.1% to 0.39% of CMC in the pulp can increase the tensile strength of the paper by 40% to 509%, increase the crack resistance by 50%,and increase the kneading property by 4 to 5 times.
CMC With high replaceable property.high purity,high transparency,low viscosity,homogeneous reactions,water retention and good solution can be used as pulp additives,Coating additives,surface sizing agent.
PAC: Adding pulp to papermaking, PAC can improve the longitudinal strength and smoothness of paper, and improve the oil resistance and ink absorption of paper.
