HPS (Hydroxypropyl Starch Ether)
Hydroxypropyl starch ether is a modified starch ether produced from natural macromolecule plant material through a series of chemical and physical reactions under alkaline conditions. Non-toxic, odorless, white powder, soluble in cold water to form a transparent or translucent viscous liquid.
It is suitable for cement-based, gypsum-based, and lime-calcium-based products to thicken, retain water, resist sagging and improve workability.
