Sepiolite

Sepiolite is a complex magnesium silicate clay material that functions as a suspending aid in salt-water based spacers.  Sepiolite is a non-swelling clay that can absorb approximately its own weight of water and other liquids without the granules disintegrating when saturated. Once dispersed in the liquid spacer system using a high-shear mixer, Sepiolite entraps the liquid, increasing the viscosity of the suspension.  This structure is stable even in systems with high salt concentrations.
