Product Description
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 processBenefits from CMC as additiveRecommend dosage  
Dry pressingSticky ceramic dry mix powder,Stabilize the ceramic slip,lower green body shrinkage and higher accuracy for specification tolerance0.5%-1.0% 
 
 
 
Slip castingStabilizing the ceramic slip0.50% 
Tape castingAdjust viscosity and provide strength to the very thin and sensitive tape casting6%-7%  
 
ExtrusionProvides plasticity to the substrate in addition to wet/green strength2%-3%  
 
Injection moldingProvides rheology control during the molding step,Thermoplastic and less residue during fire stage5%-20%  
Recommend dosage is against weight and adjustable depending on the final desired characteristics.
