Product Name: Hydroxy Propyl Starch (HPS)
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. Hydroxypropyl starch ether is a non-toxic, odorless, irregular phosphorus flake or white powder, which can be dissolved in cold water to form a transparent or translucent viscous liquid. It has the properties of thickening, bonding, dispersing, emulsifying, suspending, adsorption, surface activity, and water retention.

The appearance of hydroxypropyl starch is white, hydroxypropyl starch has good fluidity, hydroxypropyl starch has good water solubility, its aqueous solution is transparent and colorless, and hydroxypropyl starch has good stability.
In building materials, it mainly resists sagging, improves workability, prolongs the opening time and thickening of cement. According to different product performance requirements of internal and external wall putty, bonding and polishing mortar, basic particles and vitrified microbeads, our factory finely classifies products.
