Welan gum is an excellent thickener and stabilizer, with high viscosity, pseudoplasticity, thermal stability and compatibility under low shear. 



Oil and Gas field

Acts as a critical spacer fluid component; 

Provides performance of viscosity enhancement and friction pressure reduction, stabilization for hydraulic fracturing, wellbore cleanup, cementing, and drilling;

Functions as a high-temperature resistant polymeric thickening agent in the secondary and tertiary oil recovery process.


In concrete or mortar compositions, it plays a critical use to reduce fluid loss, to increase the suspension properties. It significantly improves the fluidity of concrete mixtures, increases cohesion, reduces the tendency of bleeding and segregation, and has little effect on mechanical properties and durability of concrete.

In dry powder mortar, it replaces traditional thickening products such as cellulose ether, providing thickening and thixotropy performance, at low dosage.

Along with superplasticizer, it also acts as a liquefied viscosity agent.

Other Industrial Applications

Acts as a thickener, suspension agent, binder, emulsifier, stabilizer, and viscosity agent.

Hydroxyethyl cellulose, Vis-HE, Industrial Grade

Ethylcellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification of basic cellulose and ethylene oxide (or chloroethanol) Ionic soluble cellulose ethers.

Cellulose Gum, Vis-CT, Industrial Grade

Cellulose Gum (Sodium Carboxymethylcellulose) is a high purity, fine cellulose ether. It is widely used in food products and performs as multifunctional additive such as thickener, stabilizer, blinder, water retention agent and film formation agent.
