Hydroxypropyl Starch Ether-Supplier|Construction Adhesive&Textile Thickener

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 plasticizers. This product stands out as a critical component in various industrial applications, offering unique properties that enhance material performance. As a hydroxypropyl starch ether supplier, Pengze Technology (Shijiazhuang) Co., Ltd. has established itself as a leader in providing high-quality starch derivatives tailored to meet diverse industrial needs.

Key Features and Advantages

Hydroxypropyl starch ether is renowned for its fast thickening ability and medium viscosity, which contribute to its effectiveness as a functional additive. Its ability to retain water and improve the sag resistance of materials makes it particularly valuable in construction and coating applications. For instance, in tile adhesive, it ensures stability and reduces slippage, while in wall putty, it enhances workability and smoothness. Additionally, its low dosage requirement (0.3–0.5%) ensures cost-efficiency without compromising performance.
