Hydroxypropyl Starch Ether-Pengze Technology|Fast Thickening&Low Dosage



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. Unlike conventional starch or modified starch, HPS offers unique properties that make it an indispensable component in various industrial applications. This article explores the features, technical specifications, applications, and the company behind this innovative product, Pengze Technology (Shijiazhuang) Co., Ltd..

Product Overview

Hydroxypropyl starch ether is a modified starch derivative that enhances the performance of construction materials, textiles, and daily chemicals. Its ability to improve workability, reduce sagging, and extend open time makes it a preferred choice for cement-based, gypsum-based, and lime-calcium-based products. The product is available in different formulations, with the Model-301 being a widely used variant. Below is a detailed specification table for Model-301:
