Product Description

1. Product details of Carboxymethyl cellulose (CMC)
Commodity: carboxymethyl cellulose
CAS No.: 9004-32-4
Chemical formula: C6H7O2(OH)2CH2COONa
Appearance: white or light yellow powder
Molecular formula:  [C6H7O2(OH)2OCH2COONa]n
Synonyms: Carboxymethyl Cellulose, CMC, Sodium CMC, Na-CMC 

2. Introduction
It is a sodium salt of carboxymethyl cellulose ether,belongs to the anionic fiber sodium carboxymethylcellulose(CMC)
appearance of sodium carboxymethyl cellulose (CMC) ether, appearance for white or milky white fibrous powder or particles,0.5 0.7 g/cm3 density, almost odourless, tasteless, hygroscopicity.Just a cellophane tape is easy to disperse in water solution,insoluble in organic solvent such as ethanol.1% aqueous solution pH 6.5~8.5,when the pH>or <10 5,
rubber paste viscosity decreased significantly,the best performance in the pH = 7.On the thermal stability, viscosity increases rapidly under 20ºC, and 45ºC when changes slowly, above 80ºC heating for a long time can make its colloid denaturation and significantly lower viscosity and performance.Soluble in water, transparent solution;In alkaline solution is stable, encounter acid are easy to hydrolysis, pH value of precipitation occurs 2-3, meet polyvalent metal salt precipitation reaction.

3. Physical characteristics of Carboxymethyl cellulose (CMC)
It is a cellulose derivative with carboxymethyl groups (-CH2-COOH) bound to some of the hydroxyl groups of the 
glucopyranose monomers that make up the celluloe backbone.It is also called as CMC,Carboxymethyl.Cellulose Sodium,Sodium salt of caboxy methylcellulose.CMC is one of the important water solube polyelectrolyte.It can soluble in 
water,insolublein alcohol,ethanol,benzene,chloroform and other organic solvents.Resistant to animal and vegetableoils and not effected by illumination.
With characteristics of non-toxic,odor less,easy-absorbent,specialty cotton linter pulp is
a kind of main material to create cellulose ethers (such as CMC,HEC,HPMC,MC,etc.),And it is widely used in food,
medicine,daily chemicals, plastics,electronics,paper making,metallurgy,aerospace and other field,known as "special industrial monosodium glutamate"

4. Application of Carboxymethyl cellulose (CMC)
It is widely used in food-making as thickeners,emulsifiers,it can alsobe used in detergent,papermaking,oil-drilling,textile,
dyeing,ceramic,construction,paint,welding,battery,medicine,tobacco,toothpaste,cosmetic,and so on.Used as thickening
agent in food industry,pharmace utical industry used as drug carrier,used as adhesives in daily chemical industry,
resistance to low dose.
Used as sizing agent and printing paste in printing and dyeing industry such as protective colloid.
Oil can be used as a fracturing fluid in petroleum and chemical composition.

5. Storage and transportation of Carboxymethyl cellulose (CMC)
This product storage should pay attention to the moistureproof,fire prevention,prevent heat,requirement in ventilation,
dry place.Transportation,loading and unloading when rainproof hook is strictly prohibited.This product long-term
storage plus heap pressure may occur,unpacking agglomerate,will cause inconvenience but won't affect quality use.This product storage when in contact with water is strictly prohibited,otherwise will occur gel or partly dissolved and cause cannot use.
