Ceramic Grade Carboxymethyl cellulose

Ceramic Grade Carboxymethyl cellulose is a light cream to white free flowing powder or granulate, that readily dissolves in water to form clear, viscous solutions.

Our Ceramic Grade CMC is particularly suited for use as binders and provide high strength to the unfired substrate at relatively low addition levels while producing excellent plasticity,good suspensions,uniform slurries and low residue upon firing.

Our CMC is used as the most efficient binders,thickeners and stabilizers in ceramic glazing to provide:

* Assisting in the formulation of stable glaze suspensions
* Tailoring the flow and application to the situation
* Directly controlling the drying rate of the glaze as it is applied
* Increasing the mechanical strength of unfired glaze surfaces
* Promoting uniform pigment dispersions for uniform color

We recommend low to medium viscosity CMC with typical addition level 0.1-0.5% against weight depending on the final desired characteristics of the glaze.

Besides glazing,our CMC can be used in whole process during ceramic production:

Ceramic production process	Benefits from CMC as additive	Recommend dosage
Dry pressing	Sticky ceramic dry mix powder,Stabilize the ceramic slip,lower green body shrinkage and higher accuracy for specification tolerance	0.5%-1.0%



Slip casting	Stabilizing the ceramic slip	0.50%
Tape casting	Adjust viscosity and provide strength to the very thin and sensitive tape casting	6%-7%

Extrusion	Provides plasticity to the substrate in addition to wet/green strength	2%-3%

Injection molding	Provides rheology control during the molding step,Thermoplastic and less residue during fire stage	5%-20%

Recommend dosage is against weight and adjustable depending on the final desired characteristics.

Brief Properties of our CMC for Ceramic
High Degree of substitution
High degree of substitution smooth the rheology of the aqueous solution and give improved compatibility.
