Ceramics Processing

with METHOCEL™

We offer a range of polymers for ceramics that may significantly reduce your production costs.

METHOCEL™ cellulose ethers are versatile, water-soluble polymers with a combination of valuable properties you won’t find in any other ceramic binder. Not only are they highly efficient binders with excellent burnout characteristics, they can also serve as lubricants, emulsifiers, suspending agents, and surfactants. As a result, a single METHOCEL product can often perform functions that would require separate additives if another binder were used. 

Benefits of Ceramics Processing with METHOCEL™

Tape casting. Use of Methocel products provides better flow and leveling and more uniform thickness. Low sodium residues provide the purity necessary for electronic items. Thermal gelation reduces binder migration and surface faults.

Extrusion forming. Used as a temporary binder and processing aid, METHOCEL cellulose ethers allow precise control of rheology in ceramic mixes, permitting broader operating ranges. Lubricity reduces energy consumption and die wear and promotes smoother surfaces. Thermal gelation permits extrusion of extremely delicate, thin-walled shapes without sag or deformation.

Dry and isostatic pressing. METHOCEL products provide optimum grain lubrication for tighter, more uniform packing. The results are more predictable green densities, less shrinkage during firing, and higher fired strengths.

Glazes/porcelain enamel. METHOCEL cellulose ethers improve control of viscosity and rheology and fire out completely in the kiln.

Injection molding. Use of METHOCEL cellulose ethers provides higher green densities and better green strength. In high-temperature coatings/refractory mixes and mortars, METHOCEL improves workability and application properties. Because METHOCEL products have low ionic salt residues, they won’t lower melting points. In fact, they can permit a reduction in use of plasticizers with low melting points.

Additional Ceramic Processing Options

POLYOX™ Water-Soluble Resins are used as binders and forming aids in ceramic parts, ceramic bricks, ceramic fibers, and ceramic extrusion.

ETHOCEL™ is used in solvent based ceramic applications as a rheology modifier and binder.  It provides green strength to the unfired ceramic and burns out cleanly, leaving no residue after firing.

WALOCEL™ CRT is used in glazes as a thickener and binder to provide stability, strength, and aesthetic enhancements such as glossiness and brilliance of the glaze.
