Product Description
Diutan Gum is a high molecular weight polysaccharide gum synthesized by the fermentation process with strains of Alcaligenes sp.with carbohydrates such as sugar ,bean flour etc.is no block when dissoving in the water, can be widely used in construction concrete, oil drilling and other industrial field.
Introduction
Diutan gum is a natural high-molecular-weight gum produced by carefully controlled aerobic fermentation. It is widely used in concrete, self-leveling, plaster, cement grinding aid and oil drilling, well completion with high suspension and high stabilization.
Diutan gum , is widely used in concrete, self-leveling, plaster, cement grinding aid and oil drilling, well completion with high suspension and high stabilization. It has better pseudoplasticity, high viscosity in slow-speed shearing rate, it is a polymer rheological regulator used for oil drilling and well completion . In a high temperature condition the viscosity do not change with the temperature changes.
Features of Biogums Diutan Gum
High-performance viscosity improver.
High viscosity under low concentration.
High viscosity under slow-speed shearing rate
Pseudoplasticity thinning under high shear.
Good stability in a high salt and high temperature condition.
Excellent water solubility.
Good water holding capacity.
Excellent Thickening Properties: It provides high viscosity even at low concentrations, delivering strong thickening effects.

Applications of Biogums Diutan Gum
- cement-based material : as a kind of rheology modifier, Diutan Gum could improve low shearing rheology viscosity (LSRV), to decrease anti-sedimentation or bleeding, targeted for use in super plasticizer system.
- Oil Drilling fluid：improve the rheology of oil drilling fluid, enhance the stability of viscosity under high temperature.
- In agriculture: Crop protection products such as herbicides, insecticides, and fungicides; animal insecticide ; grassland pests control products.
