3.Main application
Sodium carboxy methyl cellulose (CMC) is the largest output in cellulose ether class and used the most extensive and the most convenient product, commonly known as "industrial monosodium glutamate". The main features of the CMC is to form a high viscosity of the colloid and solution, it can thickening, flow, emulsification and disperse, informs and keeping water, protect colloid, film forming, acid resistance, salt resistance, suspended turbidity and physiological harmless, so it’s widely used in the area of food, medicine, cosmetic, petroleum, paper making, textile, construction etc.
4.Considerations for Packaging, Storage and transportation
Sodium carboxy methyl cellulose (CMC) use textile bag as the outer packing and plastic film bag as the inner packing. 25kg net weight per bag. Storage keep should pay attention to the moistureproof, rain, stored in ventilated dry place.
