Product Description

Product Description

Sodium Carboxymethyl Cellulose (also referred as CMC and Carboxy Methyl Cellulose) can briefly be described as an anionic water-soluble polymer produced from naturally occurring cellulose by etherification, substituting the hydroxyl groups with carboxymethyl groups on the cellulose chain.

Being readily dissolved in hot or cold water, Sodium Carboxymethyl Cellulose CMC can be produced in different chemical and physical properties.

These properties can affect the performance of the product (CMC) in the application, furthermore can be essential for optimizing the production costs.

There are a number of parameters which define the properties of the Sodium Carboxymethyl Cellulose CMC.

√ Purity (active CMC content): inevitably CMC powder is produced with by products that are sodium salts which comes in the product Sodium Carboxymethyl Cellulose content in the product is the purity.

√ Viscosity: one of the most interesting characteristics of the CMC powder is the viscosity which can be from low to high. It is measured mostly by digital viscometers at certain temperatures in different solution rates; such as 1%, 2% or 4%.

√ Degree of Substituion: is the average number of sodium carboxymethyl groups per anhydroglucose unit on the cellulose back bone. This parameter in some application areas is quite important to control in the product.

√ Physical form: the CMC powder can be produced in fine powder to dust-free granule.

Sodium carboxymethyl cellulose Storage:
Stockpiled at the ventilated place, avoiding rain, moisture and insolation. Please handle with care to prevent bag damage, store away from toxic substances.
 

Our Advantages

Property:
White to off white powder or particles, it is soluble in water. Degree of substitution is an important factor influencing water solubility and the viscosity of sodium carboxymethyl cellulose also has a great effect on the water solubility.

 

Density	1.050 g/cm3(Temp: 15-18 °C)
Solubility	Practically insoluble in anhydrous ethanol. It swells with water to form a suspension and becomes viscid in 1 M sodium hydroxide.
Shape	Preswollen, microgranular
Stability	Stable. Combustible. Incompatible with strong oxidizing agents.
Scope of use	Suitable for various water-based drilling fluids
Package	The packaging is a three-in-one paper-plastic composite packaging bag (that is, kraft paper, polypropylene woven bag, and polyethylene film are combined into one whole), lined with plastic bags. The net weight of each bag is 25kg, and the allowable error is 5%. The inner and outer seals of the packaging bags should be tied separately to prevent moisture and damage.
Transportation	During transportation, it should be protected from sun protection and collision leakage.
Storage	Product storage should be kept ventilated and dry, avoid rain, and keep away from heat sources. The shelf life of this product is 2 years.

Application

 

The different types of detergent grades of CMC are produced in the limits of detergent grade specifications but they will be divided into different variations due to customer demands. The customer satisfaction, price sensitivity and other expectations are fully covered by these variations.

CMC PAC Oil Drilling Grade:  
CMC and PAC can reduce water loss, and increase viscosity in drilling fluid, cementing fluid and fracturing fluid. They play the roles of protecting the wall of well, taking drilling trifles, protecting drilling bit, preventing mud loss and increasing drilling rate.
Usage: add to mud directly or glue solution preparation.
Addition: 0.1-0.3% in fresh water mud; 0.5-0.8% in salt water mud.

CMC Food Grade
CMC is widely used in food industry, it play the roles of taste improvement, thickening and stabilization when used in various kinds of dairy drinks and seasonings. As an additive of molding, taste improvement, anti-fragmentation, water retaining and tenacity strengthening, CMC is also used in ice cream, bread, cake, biscuit, instant noodle and fast paste foods.
The recommended addition is 0.3-1.0%.

CMC Textile Grade
Is ready to replace traditional sodium alginate with about half of the cost.

CMC Ceramic Grade
Can be used for water preserving in concrete paste and color paste, as adhesive in concrete, sand, and in adhesive layer for wall paper installation.CMC is used for ceramic embryo, glazing pulp and colored glaze in ceramic industry.
Addition: 0.03%-0.2% used in ceramic embryo; 0.05-0.2% used in glazing pulp; 1.4-4.0% used in colored glaze.

CMC Toothpaste Grade
CMC has an efficiency of adhesion and molding when used in toothpaste, and stabilizes the quality of toothpaste owing to good compatibleness.
The recommended addition is 0.5-1.5%.

Other Industries
As coagulant, water retaining, thickener and binder, Sodium Carboxymethyl Cellulose CMC is also used in paint, carpet gum, mosquito coil incense, tobacco, electric welding, mining, battery, printing and others.

Usage:
1.  In Detergent powder, it is used as a soil suspension polymer designed to deposite onto cotton and other cellulosic fabrics, creating a negatively charged barrier to soils in the wash solution.
 
2. CMC is used in food as a viscosity modifier or thickener and to stabilize emulsions in various products including ice cream.
 
3. It is also a constituent of many non-food products, such as toothpaste, laxatives, diet pills, water-based paints, textile sizing, and various paper products.
 
4. In the oil-drilling industry, as an ingredients of drilling mud, where it act as a viscosity modifier and water retention agent.
 
5. Sometimes, it is used as an electrode binder in advanced battery applications.
