Hydroxypropyl Starch Ether - Pengze Technology | Construction, Textile, Chemical Solutions

Hydroxypropyl starch ether (HPS) is a fine white powder derived from natural plant materials through a modified, highly etherified reaction followed by spray drying. Unlike conventional starch or modified starch, HPS is engineered to enhance performance in diverse industrial applications. This article explores its functional benefits, technical specifications, and real-world applications, supported by authoritative insights from the National Institute of Standards and Technology (NIST).

Product Overview

Hydroxypropyl starch ether is a hydroxypropyl starch ether that serves as a critical additive in construction, textiles, and chemical industries. Its unique molecular structure provides superior thickening, water retention, and stability, making it indispensable for applications ranging from wall putty to oil drilling. The product is available in multiple variants, including sodium hydroxypropyl starch phosphate and hydroxypropyl starch.
