Xanthan Gum, also known as Han Sheng Gum, is a microbial extracellular polysaccharide produced by the fermentation of carbohydrates by the bacterium Xanthomonas campestris. It appears as a white or light yellow free-flowing powder.

Poly Anionic Cellulose (PAC) is a high-purity, high-degree-substitution sodium carboxymethyl cellulose (Na-CMC), representing a premium grade within the CMC family. It appears as a white or off-white free-flowing powder with very high purity and excellent dissolution properties.

Sodium Carboxymethy Cellulose (CMC) is a kind of anion polyelectrolytes, sodium chloroacetate with alkaline cellulose reaction，Have separately: HV-CMC、MV-CMC、LV-CMC and Alkaline of MV-CMC. As the white or pale yellow powder appearance，Non-toxic，Soluble in cold or hot water，as sticky colloid

80A-51 is a high-efficiency viscosifier for water-based drilling fluids, primarily composed of high-purity polymers. It appears as a white or slightly yellow free-flowing powder, readily soluble in water, and quickly forms a highly viscous colloidal solution.

The Ammonium Salt of Hydrolyzed Polyacrylonitrile (NH4-HPAN) is an anionic polyelectrolyte produced by the hydrolysis of polyacrylonitrile (e.g., from acrylic fiber waste) with ammonia water under high temperature and pressure.
