Application

CMC is an anionic water-soluble polymer based on renewable cellulosic raw material. It functions as a rheology modifier, binder,  dispersant, and an excellent film former. These attributes make it a preferred choice as a bio-based hydrocolloid in multiple applications.

Used as thickener, stabilizer, protective colloid, suspending agent, gelling agent, flow control agent and more.

Food and beverage: as an emulsion stabilizer and thickener to improve mouthfeel and protein stabilization.

Pulp and paper industry: AKD sizing and coating.

Mining: specially for mineral flotation and depressants.

Oil and gas: high-performance polymer with PAC extend the performance of water-based drilling additives.

Also for Personal care, Paint, coating and inks, battery industry, and ceramics.
