Hectorite-High-Temperature Flow Modifier

This product is a high-temperature-resistant flow modifier for water-based drilling fluids, manufactured from natural sepiolite through modification. It is a pure natural, non-toxic, odorless, asbestos-free, and non-radioactive hydrated magnesium silicate clay mineral. Microscopically fibrous in structure, it disperses readily in water and highly polar solvents. Its randomly dispersed fibers form a network structure, delivering excellent suspension and rheological properties. This product exhibits excellent salt resistance and high-temperature stability. Drilling fluids formulated with it do not flocculate at elevated temperatures, remain unaffected by charged ions in saline water, and demonstrate nearly identical hydration expansion in both fresh and salt water. It is a commonly used flow modifier in saltwater, seawater, and high-temperature drilling applications. Additionally, it is partially acid-soluble, making it an ideal material for formulating completion and workover fluids.
