Cas no.: 9003-04-7 Formula: (c3h3nao2)n Density: 1.32 g/ml at 25 °c that normally happens to cmc and sodium alginate. The viscidity is about 15~20 times higher than cmc and sodium alginate. It shows high alkali-resistant, minor change in viscosity after longtime storage, and not easily decaying. 1¡ê©packed in net 25kg polywoven bag lined with well-sealed pe inner bags. Pretected from moisture and avoid contact with acid, alkaline and metal ions. 2) store in a dry, closed container and protected from rain.
