Chemical Properties:
CMC is a kind of cellulose ether with anion contours high molecular structure. It has no smell, no taste and no toxicity. The white to off-white powder and graininess can be easily melt in water and become colloidal solution, but it cant melt in alcohol, ether, acetone and other organic solvent.
Applications:
1Food Grade CMC
2 Detergent Grade CMC
3 Oil-drilling Grade CMC
4 Paper Grade CMC
5 Textile, Dyeing Grade CMC
6 Ceramics, Construction, Paint Grade
7 Welding, Battery Grade CMC
8 Toothpaste Grade CMC
9 Tobbaco Grade CMC
Package:
In 25kg Kraft bag or woven bag.
