Sodium carboxymethyl starch (CMS) is a type of modified starch etherified with carboxymethyl groups. Its performance surpasses that of carboxymethyl cellulose (CMC, making it the optimal alternative to CMC. CMS finds extensive application in the papermaking industry. When added to fillers, it acts as a stabilizer, enhancing thickening and binding effects, resulting in glossy and vibrant paper, improved printing performance, increased toughness, and abrasion resistance. As pulp additive, it improves retention and filtration effects. Additionally, it is utilized in surface sizing, significantly boosting paper dry and wet strength, oil resistance ink absorption, and water resistance. When used in coating adhesives, it enhances paper production and performance.
