Introduction to Hydroxypropyl Starch Ether
Hydroxypropyl starch ether (HPS) is a fine white powder derived from natural plant materials through a highly etherified process, followed by spray drying without the use of plasticizers. This innovative material is distinct from conventional starch or modified starch, offering unique properties that make it a valuable additive in various industries.

Key Features and Advantages
Hydroxypropyl starch ether is renowned for its fast thickening ability, medium viscosity, and moderate water retention. These properties make it an ideal additive for improving the workability of construction materials. Additionally, its sag resistance and crack resistance are particularly beneficial in tile adhesives and wall putty applications.
- Low Dosage Requirement: Only 0.3-0.5% is needed to achieve significant performance improvements.
- Compatibility: Works seamlessly with methyl cellulose ether, enhancing the internal structure of materials.
- Extended Open Time: Allows for smoother and more efficient construction processes.
