NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of high-quality chemicals for various industries, and our Sodium Carboxymethyl Cellulose (CMC) is a standout product for the papermaking sector. In the intricate process of paper manufacturing, CMC offers a multitude of benefits that contribute to both the quality of the final product and the efficiency of production. Its application in papermaking is multifaceted, ranging from its use as a surface sizing agent to its role in pigment coating and wet-end additions.

As a surface sizing agent, CMC provides favorable rheological and film-forming properties. This helps in reducing surface pores, enhancing oil resistance, and improving the brightness and gloss of the paper. The increased surface strength and abrasion resistance imparted by CMC also lead to reduced printing dust and a higher quality print finish. When used as an excipient in pigment coating, CMC contributes to the internal cohesive power of the coating layer, further refining print quality and smoothness.

Moreover, CMC can be added in the wet-end process to enhance the residence of fine fibers and fillers, thereby improving the paper's wet and dry strength. The suggested dosage for CMC in papermaking applications typically ranges from 0.3-1.5%. NINGBO INNO PHARMCHEM CO.,LTD. provides specialized CMC paper grade products tailored to meet the diverse requirements of paper manufacturers.
