Buy Sodium Carboxymethyl Cellulose (CMC) – High-Viscosity Binder

Sodium Carboxymethyl Cellulose (CMC) is a cellulose derivative created through the chemical modification of natural cellulose. It functions as an effective rheology modifier, water retention aid, 和 emulsion stabilizer. Known for its high solubility in cold and hot water, CMC delivers consistent performance in a wide range of industries including food processing, oil and gas, ceramics, construction, paints, detergents, 和 paper manufacturing.

卡文资源 offers industrial, food-grade, and technical-grade CMC in bulk quantities, manufactured under strict quality standards. We ship globally and cater to the custom formulation needs of manufacturers and wholesale buyers.

⚙️ Production Method

1. Alkalization

• Cellulose is treated with sodium hydroxide (NaOH) to produce alkali cellulose.

2. Etherification

• Alkali cellulose reacts with monochloroacetic acid to form sodium carboxymethyl cellulose.

3. Purification & Drying

• Product is neutralized, filtered, dried, and milled into a fine white powder.

🏭 Applications & Industry Use Cases
