Ceramic High-Plasticity Clay
PRESTIGE®
The PRESTIGE® line of high-plasticity ceramic clays is designed to improve plastic forming, extrusion and clay body production. With strong dispersion in water and reliable working properties, PRESTIGE clays help manufacturers build strength, plasticity and handling performance into ceramic body formulations. The PRESTIGE line includes multiple clay blends for different formulation and processing needs, making it suitable for a wide range of ceramic manufacturing operations.
PRESTIGE clays can be used in blunging, direct slip make-down, filter pressing, extrusion, mulling and spray drying. Across these production methods, the material’s fluid pickup, moisture retention and formed strength contribute to more predictable processing from batch preparation through handling. For ceramic manufacturers producing decorative ware, tableware, electrical porcelain and other ceramic goods, PRESTIGE offers a flexible clay platform backed by Covia’s ceramics expertise, customer service and supply network.
Product Highlight
PRESTIGE high-plasticity ceramic clays bring together workability, strength and processing versatility for ceramic body formulations. The product line is designed for manufacturers that need clay bodies to form cleanly, hold shape and move through production without cracking or deformation.
In water-based processes, PRESTIGE clays disperse readily for direct slip make-down by blunging. Their suspension properties and rheological stability make them useful in slurry preparation, filter pressing and spray drying, while their plastic properties make them well suited for extrusion and mulling prior to extrusion.
PRESTIGE clays also perform across a broad moisture range. That operating flexibility gives ceramic bodies the firmness, strength and moisture retention needed for automated processing and handling. Compatibility with a wide range of fluxes and nonplastics adds further flexibility for manufacturers adjusting body formulations to meet product and process requirements.
