Frequently Asked Questions
Q: What are the primary industrial applications of Sodium CMC?
CMC is widely used in construction chemicals, surfactants, medical excipients, and food processing due to its thickening, stabilizing, and water-retention properties.
Q: How does CMC improve construction mortar and pastes?
It provides excellent water retention, which prevents the paste from drying too quickly and cracking, ensuring better adhesion and workability.
Q: Is Sodium Carboxy Methyl Cellulose safe for medical use?
Yes, it is a natural polymer derivative known for its physiological harmlessness and is frequently used as a medical excipient.
Q: What is the recommended storage condition for CMC powder?
Store in a cool, dry place away from sunlight. Unopened packaging can last for several years, but open bags should be sealed to avoid humidity.
Q: How does the degree of substitution affect CMC performance?
The degree of substitution (typically 0.6-0.9) influences the solubility and viscosity of the polymer, affecting how it interacts with other chemicals in a formulation.
Q: What is the standard packaging for bulk orders?
Our CMC is packed in multi-layer paper bags lined with polyethylene, with a standard net weight of 25KG per bag.
