Cellulose ethers are versatile, water-soluble, and highly efficient binders with excellent burnout characteristics, for ceramics they can work as the binder that gels at elevated temperatures to improve cohesion, increase green strength, and eliminate binder migration.
They can also serve as lubricants, emulsifiers, suspending agents, and surfactants. At elevated temperatures, solutions of Celpro® cellulose form a three-dimensional gel structure that gives extra stability to green ceramic bodies during drying and early stage firing. Thermal gelation also inhibits binder migration to surfaces, reducing the potential for stress cracks and blisters during firing.
Most importantly, Celpro® cellulose polymers contribute remarkably plastic-like properties to ceramic mixes. With Celpro cellulose, ceramic processing so closely parallels thermoplastic processing that conventional plastics technology and equipment (i.e., extrusion and injection molding) can often be utilized with little modification. As a result, Celpro cellulose ethers present unique options for the high volume production of intricately shaped, dimensionally stable ceramic items.
Our Celpro® cellulose ethers are used extensively across many ceramics applications ranging from bricks and tiles to pottery and bathroom appliances. The term of ceramics describes inorganic and nonmetallic basic materials. Generally they are formed from raw materials at room temperature and derive their typical characteristics through a sintering process at high temperatures. Often, these ceramic materials are called high-performance ceramics whose composition is different from a clay mineral. They are characterized by their special properties such as a high temperature resistance, high mechanical and chemical stability or low electric conductivity. Celpro cellulose ethers are primarily used for the chemical engineering of high-performance ceramics as process auxiliary. Depending on the application, special Celpro grades are used.
