HPS
Hydroxypropyl starch ether (HPS) is a non-ionic, soluble starch derivative, which is prepared by etherification of natural starch with propylene oxide. It is a functional additive with excellent thickening, stability, water retention and vertical flow resistance, and is widely used in building materials, food processing and medicine. HPS can form a uniform colloidal solution in water, which significantly improves the viscosity of the system and provides excellent rheological properties. This makes HPS an ideal thickener for building materials and coatings. HPS can effectively reduce the loss of water in high temperature environment and improve the water retention capacity of the material. This feature is particularly important in cement mortar and gypsum based materials, helping to extend operation time and improve construction performance. By improving the adhesion properties of materials, HPS can effectively enhance the construction performance of mortar, putty and paint on the vertical surface, preventing the slide and vertical flow of materials during construction.
HPS is easily dispersed in water and can quickly dissolve and form a stable solution. Under different pH and temperature conditions, the solution showed good chemical stability.
