Product description

Hydroxypropyl Starch ether is an ionic starch ether produced by a series of chemical and physical reactions under alkaline conditions with natural polymer material-starch as raw material. HPS is a non-toxic and odorless white powder, soluble in cold water, with good water solubility, forming a transparent and translucent viscous liquid. It has the functions of thickening, bonding, dispersion, emulsification, suspension, adsorption, surface activity, and moisture retention.

Starch ether is a starch-based additive for dry mortar in construction industry, they can improve the performance and optimize the processing performance of dry mortar by changing the thickness and rheology of various dry mortar based on cement and gypsum.starch ether should be used in combination with cellulose. It behaves well under neutral and alkaline conditions and is compatible with other additives in gypsum or cement-based building materials.


In construction materials, it mainly resists sagging, improves workability, extends the open time and thickens of cement. Subject to the differences between internal and external wall putty, bonding and polishing mortar, polystyrene particles and vitrified beads.
