Hydroxypropyl starch ether (HPS) is a fine white powder derived from natural plant materials through a highly etherified modification process. Unlike conventional starch or modified starch, HPS is spray-dried without plasticizers, making it a unique and effective additive in various industrial applications. This article provides a detailed analysis of its features, technical specifications, applications, and the company behind this innovative product—Pengze Technology (Shijiazhuang) Co., Ltd.
Hydroxypropyl starch ether is a modified starch derivative designed to enhance the performance of construction materials, textiles, and daily chemical products. Its chemical structure allows it to improve workability, water retention, and structural stability in formulations. The product is particularly valued for its ability to reduce the need for cellulose ethers while maintaining or even enhancing material properties.
