Carboxymethyl Cellulose (CMC) | Industrial Grade Technical Datasheet
一、 Product Brief
Industrial-Grade Carboxymethyl Cellulose (CMC) is a high-purity anionic water-soluble cellulose derivative modified from natural raw cellulose. As a core petroleum drilling additive and professional papermaking auxiliary polymer, it features outstanding thickening, water retention, suspension, film-forming and rheological stabilization properties. With stable chemical activity, high water solubility and adjustable viscosity, industrial CMC is specially customized for oilfield exploitation and paper manufacturing industries, delivering stable and efficient auxiliary performance for heavy-duty industrial production scenarios.
二、 Industrial Application Scope
1. Petroleum Exploitation Special Additive
CMC is a vital industrial polymer widely applied in oil and gas drilling engineering. It serves as a high-efficiency drilling fluid treatment agent, which can effectively increase mud viscosity, reduce water filtration loss, and form a dense protective filter cake on the wellbore wall. It stabilizes wellbore structure, prevents collapse and sand settling, and improves the suspension and carrying capacity of drilling mud for rock cuttings. Adaptable to high-temperature and complex stratum environments, it effectively reduces drilling resistance, lowers construction risks, and improves overall drilling efficiency and safety.
2. Papermaking Industrial Auxiliary Agent
In the papermaking industry, industrial CMC acts as a multifunctional paper-making additive for surface sizing and internal pulp addition. It significantly enhances paper tensile strength, folding resistance and surface smoothness, improves pulp retention rate and fiber bonding performance, and reduces pulp loss. Additionally, it optimizes paper surface water resistance and printing adaptability, effectively improving finished paper quality and reducing overall production costs for paper mills.
3. Other Auxiliary Industrial Applications
In addition to core oilfield and papermaking scenarios, CMC can also be used in industrial water treatment, ceramic manufacturing and detergent processing. It plays a key role in thickening, anti-sedimentation and system stabilization, meeting diversified industrial auxiliary production demands.

四、 Product Superiority
- Professional Industrial Adaptability: Customized for petroleum drilling and papermaking industry, with stable viscosity and excellent stratum & pulp adaptability, perfectly matching industrial production standards.
- Excellent Water Solubility: Fine powder with uniform mesh size, dissolves rapidly in water without agglomeration, ensuring efficient on-site construction operation.
- Stable Chemical Performance: Controlled substitution degree and low impurity content, maintaining stable thickening and stabilizing effects under complex working conditions.
- Cost-Effective Industrial Solution: Low comprehensive dosage, significantly improving production efficiency and reducing auxiliary material costs for oilfields and paper mills.
五、 Storage & Handling
Industrial-grade CMC powder must be hermetically stored in a dry, cool and ventilated warehouse, avoiding moisture, high temperature and direct sunlight to prevent performance attenuation and caking. During on-site use for drilling fluid preparation and papermaking sizing, the powder should be slowly added into stirring clean water to ensure full dissolution. The dissolution concentration and feeding dosage can be adjusted flexibly according to actual oilfield stratum conditions and papermaking process requirements to achieve optimal application effect.
