Gerneral Overview
Economical construction cmc powder sodium carboxymethyl cellulose is a cost-effective thickening additive for ordinary building mortar. Our cmc cellulose can partially replace HPMC in conventional mortar systems.
Core Product Advantages
1. Extremely High Cost Performance: Greatly reduces additive cost while meeting the performance of ordinary mortar, improves market competitiveness.
2. Stable Thickening & Water Retention: Meets the thickening and water retention requirements of mortar under normal construction conditions, prevents rapid drying and cracking.
3. Stable Batch Quality: Strict production quality control ensures small index fluctuation per batch and stable mortar formula performance.
4. Convenient & Efficient Use: Mix evenly with other dry powder materials, good dispersibility and no agglomeration.
Product Specifications
Construction Grade Sodium Carboxymethyl Cellulose (5000 mPa·s, DS:0.72) is a medium-viscosity multifunctional anionic cellulose ether and universal cost-effective building modifier. It balances moderate thickening, reliable water retention and good fluidity, improving mortar workability and extending construction time. It resists drying shrinkage cracking, features stable performance and wide compatibility for most conventional dry-mix mortar systems.
