VEKEN® Xanthan Gum (XC polymer)
CAS NO.: 11138-66-2   EINECS NO.: 234-394-2   H.S. CODE: 391390
Molecular Formula: C35 H49 O29
 
Product Description:

VEKEN® Xanthan Gum, also named XC polymer, is a kind of extracellular acidic hetero-poly saccharide fermented by Xanthomonas. It is a macromolecule microbial polymer, made from carbohydrate, like corn starch, by microbe fermentation engineering cultivation, extraction, drying and grinding. Due to its excellent heat stability, salt stability and rheological property, it is the best drilling fluid stabilizer, thereby being widely used in multiple industries, such as petroleum, geological mining and textile, etc. 

Application:
 
1. Xanthan Gum (XC Polymer) is a low-solid, cost-effective viscosifier, being widely used in oil drilling fluid, completion fluid and work-over fluid. It increases viscosity in all water based system fluid.

2.  Xanthan Gum can keep drilling fluids have viscosity constantly, from below freezing to 270°F (130°C) in static bottom hole temperature, and in a PH range from 5 to 8. It is non-toxic as well as biodegradable.

3.  Its excellent shear-thinning characteristic not only increase penetration rates in high shearing speed, but also provide excellent suspending action for optimum hole cleaning in low shearing speed while viscosity is regained.
