Applications
1. For Food & Beverage Stabilization: Carboxymethyl cellulose (CMC, CAS 9004-32-4) acts as a thickener, stabilizer and water-retention agent in ice cream, beverages, sauces, dressings and bakery products, improving body, mouthfeel and freeze-thaw stability at low dosage.
2. For Oil & Gas Drilling Fluids: Drilling-grade CMC is a reliable fluid-loss control agent and viscosifier for water-based mud systems, providing stable rheology, high salt tolerance and effective filtration control under demanding drilling conditions.
3. For Detergent Formulations: As an anti-redeposition agent in laundry and industrial detergents, CMC suspends soil particles in wash water and prevents them from re-depositing onto fabrics, keeping textiles cleaner after repeated washing.
4. For Paper Making & Coating: CMC improves dry strength, surface smoothness and ink receptivity in paper and board production, and is widely used as a coating binder and sizing agent in the paper industry.
5. For Textile Sizing: CMC provides uniform film formation and high viscosity stability as a warp sizing agent, reducing yarn breakage and improving weaving efficiency in textile manufacturing.
6. For Ceramics & Welding Electrodes: As a binder and plasticizer in ceramic bodies, glazes and welding electrode coatings, CMC enhances green strength, workability and uniformity of the final products.
7. Consistent Quality For Global Industry: Supplied as high-purity white powder or granules in food, industrial and drilling grades with customizable viscosity, CMC gives food, drilling, detergent, paper, textile and ceramic manufacturers a dependable water-soluble polymer with stable supply and flexible packaging.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
