Product Q&A

Q:How does CMC improve paper quality during production?
A:
It acts as a surface sizing agent and dry strength enhancer. It improves fiber bonding, increases tensile strength, reduces dusting, and enhances surface smoothness for better printing results.
Q:What is the recommended addition ratio of CMC in papermaking?
A:
Typical dosage ranges from 0.3% to 1.5% of dry pulp weight, depending on paper grade and target performance. We provide formulation guidance based on your specific production setup.
Q:Will CMC affect the whiteness or brightness of finished paper?
A:
No. Our high-purity CMC has minimal color impact. It preserves natural brightness and is compatible with optical brightening agents used in high-grade paper production.
Q:Is this CMC suitable for both coating and internal sizing applications?
A:
Yes. It works effectively as a coating binder for pigments and as an internal sizing additive to enhance sheet strength and uniformity across the paper structure.
Q:What is your lead time and packaging option for bulk orders?
A:
Standard lead time is 7-10workdays. Packaging available in 25kg kraft paper bags. Custom packaging also available upon request.
