DuPont Global Specialty Solutions is a vital supplier and partner to the Ceramics Industry. Through our established and novel range of polymers like METHOCEL™ and POLYOX™, we support customers around the globe to develop, optimize and manufacture world-class ceramic products.

Our unique polymer offering delivers an extensive range of functional properties in ceramic products like binding, stabilizing and lubrication, enabling extrusion processes as well as improving product performance and quality.

 
 
 

EXTRUDED CERAMICS APPLICATIONS

A typical application of extruded ceramics includes advanced ceramic substrates and particulate filters.  DuPont’s product range includes METHOCEL™ cellulose ethers and POLYOX™ water-soluble poly(ethylene oxide) polymers that help the customers to:

  • Address specific product needs
  • Precisely control the rheology in ceramic mixtures
  • Enable a broad operating range

OTHER CERAMIC APPLICATIONS

Some additional applications in ceramics are Glazes for which our WALOCELTM CRT cellulose ether class is used extensively. In tape casting, METHOCELTM cellulose ethers help enable great flow and leveling, and maintain a uniform thickness. Low sodium chloride residues provide the purity necessary for electronic items, while the product's thermal gelation properties reduce binder migration and surface faults.
