Oil exploitation grade Welan gum

Welan gum is a thickening agent whose properties make it well suited to use in high-temperature industrial applications and oilfield drilling muds.

Description: Welan gum is a specialty fermentation polysaccharide produced by fermentation of Sphingomonas sp.A key feature of this novel, water-soluble polysaccharide is its excellent stability and viscosity retention at temperatures up to 150°C (300°F).

Main properties

·            Anionic polysaccharide.

·            Excellent thermal stability.

·            Highly pseudoplastic solutions.

·            Retention of viscosity at elevated temperatures.

·            Stable over a wide range of pH and temperature.

·            Compatible with high calcium environments.

·            Stabilizes suspensions, emulsions und foams.

Stable in solutions containing high levels of glycols. It is mainly used in all aspects of industry and agriculture as a thickening agent, suspending agent, emulsifier, stabilizer, lubricants, and adhesives. It also has a wide application prospect in food, concrete, oil, ink and other industries.
