Products Description

Carboxymethyl Cellulose (CMC) is a water-soluble anionic cellulose ether derived from natural cellulose through chemical modification. It appears as a white or off-white powder or granular solid, with no odor or taste. Due to its excellent water solubility and thickening properties, it is widely used as a functional additive in various industries.

Characteristics

○ Water Solubility: Easily dissolves in cold or hot water to form a transparent, viscous solution, which is one of its most prominent features. The solubility can be adjusted based on the degree of substitution.

○ Thickening Ability: It can significantly increase the viscosity of aqueous solutions even at low concentrations, and the viscosity remains stable over a certain range of temperatures and pH values.

○ Film-Forming Property: When its aqueous solution dries, it forms a flexible, transparent film with good adhesion and barrier properties.

○ Stability: It is stable under normal storage conditions and resistant to microorganisms, ensuring a long shelf life. It also shows good compatibility with other water-soluble polymers, surfactants, and salts.

○ Pseudoplastic Behavior: The solution of CMC exhibits pseudoplasticity, meaning its viscosity decreases with increasing shear rate and recovers when the shear is removed, which is beneficial in processes requiring flowability control.
