During the “Powder Industry Roadshow” event hosted by Powder Circle, we were once again honored to receive high recognition from the powder industry. This affirmation not only reflects positive responses to Shidai Yitao's years of commitment to technological innovation and quality service, but also stands as a significant testament to our continuous dedication to the ceramic industrial auxiliary materials sector and our relentless efforts to create value for customers. With over two decades of expertise in ceramic industrial raw materials, auxiliary materials, and chemical additives, our core products focus on preservatives and rheology modifiers for ceramic wet forming processes. While auxiliary materials may seem inconspicuous in the ceramic industry, they are often pivotal to ensuring process stability and product consistency.

I. Core Products: Synergistic Empowerment of Rheology Modifiers and Preservatives
In ceramic wet forming, the state of the slurry directly impacts the density and uniformity of the green body, while also affecting the smooth progression of drying and firing processes. To achieve suitable flowability and dispersion in slurries, the industry commonly adds polymeric additives. Among these, rheology modifiers represented by sodium carboxymethyl cellulose (CMC) are the most common category. They regulate slurry viscosity and particle dispersion, enhance green body wet strength, and facilitate smoother processes like slip casting, extrusion, and casting. This helps manufacturers achieve more controllable processes and higher finished product consistency.
However, while organic additives like CMC offer process advantages, they also carry risks. Retaining cellulose characteristics in their molecular structure, they are susceptible to degradation by microbial enzymes. This vulnerability is exacerbated in warm, humid workshop environments, fostering bacterial and fungal growth. Consequently, the slurry may undergo “fermentation,” leading to viscosity reduction, foaming, off-odors, and even compromised green body quality. This is precisely where preservatives demonstrate their value. They function like an “insurance lock” for the production system, effectively inhibiting microbial growth, extending slurry stability, and preventing process fluctuations and losses caused by slurry deterioration. Complementing rheology modifiers, these agents work together to make the slurry both “easy to use” and “durable,” jointly supporting the stability of ceramic wet forming.
II. Application Scope: From Traditional Applications to Emerging Opportunities
In the traditional sanitaryware sector, rheology modifiers and preservatives are virtually indispensable for process assurance. Our products have long served production sites, helping enterprises tackle issues like slurry fermentation during high-temperature seasons and green body cracking, becoming a critical link in ensuring process stability. Company leader Shen Jinmei, with prior experience at internationally renowned ceramic enterprises, possesses deep insight into the demands for process stability and consistency. This background has sharpened her understanding of the value that auxiliary materials bring to the industry.
Today, we are also exploring broader market opportunities. For instance, in the production of honeycomb ceramic catalysts and diesel particulate filters (DPF), extrusion molding requires slurries with excellent plasticity and wet strength. In 3D-printed ceramics, slurries undergo prolonged circulation, demanding superior rheological properties and antimicrobial resistance; In high-end products like electronic ceramic roll-to-roll films and ceramic filtration membranes, even minute bubbles or viscosity fluctuations can cause film defects or yield losses.
III. Continuous Innovation: Future-Oriented Material Solutions
Though small, additives are indispensable pillars of the ceramic industry. From sanitaryware to advanced ceramics, our products consistently revolve around the core principle of “stability”: rheology modifiers enhance slurry performance for smoother forming processes; preservatives ensure slurry integrity and extended service life. Moving forward, we remain committed to our corporate mission of “empowering manufacturing through technology and creating value through stability.” We will deepen our engagement at the forefront of ceramic wet forming, delivering finer, more efficient, and greener industrial auxiliary materials to our customers. We stand as steadfast supporters and partners on the path to high-quality development for China's ceramic industry. Exploring new breakthroughs across broader application scenarios is a direction we are actively pursuing.
