 Chemical CMC Paper Grade (Sodium Carboxymethylcellulose, CMC)

Index	Technique Requirements
	ZZH-1	ZZH-2
Viscosity(mpas)	20 max (2% aqueous solution)	50 max (4% aqueous solution)
Degree of Substitute	0.85 min	0.90 min
Purity (%)	65 min	90 min

Applications: In paper industry,  CMC paper grade is used for paper coating. It is useful for the dispersing and flowing of the pigments, enhancing the finish and smoothness of the printing quality. It is used for surface sizing to strengthen the paper and reduce the printing dusts. It can increase moisture and improve retention rate in pulping.
