High-viscosity, low-substitution sodium carboxymethyl cellulose optimized for thickening and suspension stability in aqueous systems.
Excellent salt tolerance and performance retention in moderate ionic strength environments.
Consistent batch-to-batch rheological behavior due to tightly controlled degree of substitution (DS) and molecular weight distribution.
Fast hydration with minimal lumping, enabling efficient cold-water dispersion in industrial mixing processes.
Non-ionic character combined with anionic charge provides balanced compatibility with surfactants, polymers, and electrolytes.
Oilfield drilling fluids — as a viscosifier and fluid-loss control additive in bentonite-based muds.
Construction mortars and tile adhesives — for water retention, workability enhancement, and sag resistance.
Pharmaceutical suspensions and oral liquid formulations — as a stabilizer and suspending agent meeting USP/NF standards.
Textile printing pastes — providing high viscosity, shear-thinning flow, and pigment fixation.
Food-grade industrial applications where regulatory compliance and functional consistency are critical.
