Sodium Carboxymethyl Cellulose CMC Industrial Grade
Paper finishing by surface sizing can increase stiffness, smoothness, improve surface strength and air permeability, control crimp and obtain good printability. Adding a certain proportion of CMC Carboxymethyl Cellulose to the surface sizing can make the surface obtain good sealing and ink acceptance so that the color printing is clear and bright to save ink.Sodium CMC used as a surface sizing agent generally has a viscosity of 30 ~ 700mPa·S and a degree of substitution of 0.7 ~ 0.85, which has excellent film formation and whole film transfer performance。Papermaking Grade CMC can form a good sealing property and oil resistance on the surface of paper or board paper, thereby improving the surface sizing effect. CMC Polymer is usually used for paper with special requirements such as securities paper, banknote paper, release base paper, decorative paper and high-grade double-tape paper.
