Hydroxypropyl starch ether (HPS) is a fine white powder derived from natural plant materials through a modified, highly etherified reaction, followed by spray drying without the use of plasticizers. This innovative product stands out from conventional starch or modified starch due to its unique properties and wide-ranging applications. As a critical component in various industries, HPS offers enhanced performance, making it a preferred choice for manufacturers seeking reliable and efficient solutions.
Hydroxypropyl starch ether is a modified starch that undergoes a chemical process to improve its functional properties. This process involves the introduction of hydroxypropyl groups, which enhance the starch's solubility, stability, and compatibility with other materials. The result is a white, fine powder that is free from plasticizers, ensuring it meets the stringent requirements of modern industrial applications.
One of the key advantages of HPS is its ability to improve the workability of cement-based and lime-calcium-based putty products and mortars. It is compatible with other building admixtures, making it an essential ingredient in the formulation of high-performance construction materials. By incorporating HPS, manufacturers can achieve better construction outcomes, reduce the amount of cellulose ether required, and enhance the overall quality of their products.

Hydroxypropyl starch ether is extensively used in the building materials industry. It serves as an adhesive, coating, or organic liquid for various (cement, gypsum, lime, and calcium-based) wall putty additives. Additionally, it functions as an additive for decorative mortar and plastering mortar. HPS is also employed as a molding adhesive for ceramic and porcelain products, acting as a thickener and stabilizer in aqueous solutions. Its ability to suspend and emulsify makes it an invaluable component in construction materials.

In the textile industry, hydroxypropyl starch is used as a warp size to enhance wear resistance and weaving efficiency. The high substitution degree of HPS makes it an effective thickener, contributing to the production of high-quality textiles. Its ability to improve the performance of textile materials ensures that the final products meet the required standards.

Hydroxypropyl starch ether is utilized as a binder, suspending agent, and thickener in the daily chemical industry and cosmetics. Its properties make it an ideal ingredient for formulations that require stability and consistency. Additionally, in the oil drilling industry, HPS helps stabilize oil drilling boreholes and improve drilling conditions by reducing sloughing and flocculating drilling cuttings.
