Yizhong Sodium Carboxymethyl Cellulose (CMC) is an unparalleled anionic cellulose ether, meticulously derived from natural cotton fiber through sophisticated processes including alkalization, etherification, purification, drying, and granulation. This premium product manifests as a flawless white powder or granules, whose colloid solution is exceptional in thickening, stabilizing, emulsifying, suspending, and forming films. CMC stands as a cornerstone in diverse industries such as food, toothpaste, papermaking, ceramics, printing and dyeing, and most notably, in the realm of oil drilling.
Product Description


Oil Drilling Grade
Polyanionic cellulose (PAC) is a highly versatile and economically efficient water-soluble polymer organic compound. It is lauded for its superior ability to prevent shale hydration, control filtration loss, and exhibit outstanding salt resistance. An ideal choice for use in water-based drilling fluids as well as low-density brines, PAC remains an essential component in the drilling industry.
Sodium carboxymethyl cellulose (CMC) is an indispensable additive in oil drilling, serving as a highly effective oil repellent, viscosity reducer, acidification corrosion inhibitor, and water plugging agent. Its unmatched versatility and efficiency make it the preferred solution for optimizing drilling operations.

CMC plays a pivotal role in drilling, cementing, and fracturing fluids by enhancing viscosity, reducing water loss, and ensuring robust wall protection. It significantly aids in the efficient transport of drilling cuttings, safeguards the drill bit, prevents mud loss, and accelerates drilling speed. CMC can be seamlessly integrated, either directly or as a mixed glue component within the mud.
