Hydroxypropyl Starch Ether - Pengze Technology | Construction, Textile, Cosmetics

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 advanced formulation distinguishes it from conventional starch or modified starch, offering unique properties that make it indispensable in various industries. In this article, we explore the functionalities, technical specifications, applications, and the company behind this innovative product, Pengze Technology (Shijiazhuang) Co., Ltd..

Product Overview

Hydroxypropyl Starch Ether is a white, fine powder that undergoes a highly etherified modification process, enhancing its compatibility with other building admixtures. It is designed to improve workability, ensure construction efficiency, and reduce the reliance on cellulose ether. This product is particularly effective when used in conjunction with methyl cellulose ether, as it increases thickness, promotes internal structure development, and enhances crack resistance, sag resistance, and overall workability.

Key Features and Benefits

• Fast Thickening Ability: Hydroxypropyl Starch Ether provides rapid thickening, ensuring efficient processing in various applications.
• Medium Viscosity with Water Retention: It maintains a balanced viscosity while retaining water, improving the workability of materials.
• Low Dosage for High Performance: A minimal addition (0.3-0.5%) achieves significant improvements in material properties.
• Enhanced Anti-Sag Properties: Ideal for tile adhesives and wall putty, reducing sagging and improving structural integrity.
• Improved Operational Performance: Ensures smoother application and handling, reducing labor intensity.
• Extended Open Time: Allows for longer working periods, enhancing construction flexibility.
