Sodium Carboxyl Methylstarch is a kind of modified starch with carboxymethyl etherification, performance is better than that of carboxymethyl cellulose (CMC) with competive price. It is the best products to replace the CMC.

      CMS has a good performance in adhesion, thickening, water emulsion, suspension, dispersion, etc. As mud stabilizers in oil drilling and water retention agent, it could reduce the water loss, improve the stability of the coalescence of clay particles in drilling fluid role.  

Sodium carboxymethyl starch (CMS) is a kind of with carboxymethyl etherification modified starch, the performance is better than that of carboxymethyl cellulose (CMC), the best products to replace the CMC. CMS solution stability and good performance, has the adhesion, thickening, water, emulsion, suspension, dispersion, etc. In the process of CMS in oil Wells homework as mud stabilizers, water retention agent, it could reduce the water loss, improve the coalescence of clay particles in drilling fluid, stability. CMS influence on mud plastic viscosity is small, impact on the power, shear force, is beneficial to carry cuttings, especially when drilling salt-gypsum layer, can make the drilling fluid is stable, reduce loss, prevent the borehole wall collapse. Particularly applicable to high salinity, PH value of high salinity Wells.

Application:

1. mud stability 
2. water-retaining agent
3. stabilizing agent
