Product Description:

It is  high-molecular weight biopolymer, provides versatile rheology control in a wide range of brines, drilling and fracturing fluids. Xanthan gum is considered non-hazardous and suitable for use in environmentally sensitive locations and applications. It is a highly dispersible powder that can be used for a variety of oilfield applications that use standard grade xanthan gum. It is  readily disperses and can be mixed into water under low shear conditions without the formation of lumps and “fisheyes” often seen with non-dispersible polymers, improving utility and efficiency.

In addition to its improved dispersibility,it has the typical properties of xanthan gum for oilfield use – excellent rheological control for water-based drilling, completion and work-over fluids in a wide range of brines.

Product Application:

In the oil industry, Xanthan gum is used in large quantities, usually to thicken drilling mud. These fluids serve to carry the solids cut by the drilling bit back to the surface. Xanthan gum provides great "low end" rheology. When the circulation stops, the solids still remain suspended in the drilling fluid. The widespread use of horizontal drilling and the demand for good control of drilled solids has led to its expanded use. It has also been added to concrete poured underwater, to increase its viscosity and prevent washout.

In cosmetics, Xanthan gum is used to prepare water gels, usually in conjunction with bentonite clays. It is also used in oil-in-water emulsions to help stabilize the oil droplets against coalescence. It has some skin hydrating properties. Xanthan gum is a common ingredient in fake blood recipes, and in gunge/slime.


 

Product Dose:

Dosage

Depending on the requirement 0.1-0.5% calculated based on the water content.

Solutions should not contain more than 1% Xanthum Gum.Considerably higher concentrations ensure no homogenous Dispersion.

Processing

Due to its specialized chemical surface treatment, the products tend not to clump. It can be incorporated with low shear forces. Solution can be created by simply stirring it into water.

IT should be prepared an neutral to acidic pH-value- ranges. The viscosity increases in this case as a function of time until complete swelling occurs. Immediate viscosity build up can be achieved by alkalizing the solution.
