Hydroxypropyl Starch Ether (HPS)
MIKEM HPS Description
MIKEM Hydroxypropyl Starch Ether (HPS) is a spray-dried white fine powder, made from natural plants after modification and high etherification treatment. It has good water solubility, and its aqueous solution is transparent and colorless. Our HPS product is very stable under acidic and alkaline conditions. Its starch gelatinization temperature is lower than ordinary starch, and it has higher viscosity stability when the temperature changes. Besides, etherified starch can achieve better freeze-thaw stability and transparency.
Our HPS product has been applied in a variety of building materials, such as tile adhesives, cement/gypsum mortar, and various putty powders (e.g., cement-based, gypsum-based and gray calcium-based putty powder).
Our HPS product is an excellent thickener and water retention agent. With a small dosage, it can effectively increase the slip resistance, improve the workability, and extend the open time of the material.
