Attapulgite for Foundry (ObsiFerrum)
Attapulgite for Foundry (ObsiFerrum)
ObsiFerrum™ is a high-performance foundry-grade attapulgite engineered to meet the
demanding requirements of modern casting and refractory systems. With its unique
rod-shaped crystal structure, exceptional thixotropic behavior, and optimized absorption
capacity, ObsiFerrum™ delivers superior rheological control, binding strength, and thermal
stability across a wide spectrum of foundry chemical formulations.
Designed for consistent performance in complex casting environments, ObsiFerrum™ enhances mold integrity, improves coating cohesion, reduces casting defects, and supports the production of high-quality metal components. Its ability to rapidly shear-thin and recover makes it ideal for advanced processes such as slurry coatings, precision molding, and additive-manufactured refractory components.
ObsiFerrum™ offers foundries a reliable, cost-effective solution for achieving better flow characteristics, cleaner casting surfaces, and improved production efficiency.
