What is Welan gum？
Welan gum CAS 96949-22-3 is a soluble extracellular polysaccharide produced by Alcaligenes sp. through aerobic submerged fermentation. Due to its good thickening and anti-segregation properties,Welan gum is used as a good stabilizer and thickener. Cement mortar, concrete and other building materials fields.

Application
In the food industry, Welan gum can be used in the processing of baked products, dairy products, juices, milk drinks, sugar coatings, frostings, jams, meat products and various desserts.
In the petroleum industry, Welan gum can be used to prepare drilling mud to maintain the viscosity of water-based drilling fluid and control its rheological properties. Welan gum is also a new type of oil-displacing agent, which is used for tertiary oil recovery of oil wells. When Welan gum is prepared into an aqueous solution of suitable concentration and injected into the well, and pressed into the oil layer to displace oil, the oil recovery rate can be greatly improved. In addition, Welan gum can also be used as a flow improver in well completion, workover, formation fracturing and heavy oil transportation.
