Hydroxypropyl Starch Ether - Pengze Technology | Versatile Additive, High Performance

Hydroxypropyl starch ether (HPS) is a fine white powder obtained from natural plant materials through a modified, highly etherified reaction, followed by spray drying without plasticizers. Unlike conventional starch or modified starch, HPS offers unique properties that make it a critical component in various industrial applications. This article explores the product's features, technical specifications, applications, and the company behind it, Pengze Technology (Shijiazhuang) Co., Ltd.

Product Overview

Hydroxypropyl starch ether is a white fine powder derived from natural plant materials. Its highly etherified structure ensures excellent compatibility with other building admixtures, making it an ideal additive for cement-based, lime-calcium-based, and gypsum-based putty products and mortars. One of its key advantages is its ability to improve workability while reducing the amount of cellulose ether required. When used in conjunction with methyl cellulose ether, HPS enhances thickness, promotes internal structure, and provides superior crack resistance, sag resistance, and workability.

Hydroxypropyl starch phosphate is a key variant of HPS, offering enhanced stability in industrial applications.

Key Features

• Fast thickening ability: HPS provides rapid viscosity increase, ensuring efficient mixing and application.
• Medium viscosity with water retention: It maintains moisture in formulations, preventing premature drying.
• Low dosage requirement: Only 0.3-0.5% is needed to achieve significant performance improvements.
• Enhanced sag resistance: Ideal for tile adhesives and wall putty, reducing slippage during application.
• Improved workability: Ensures smoother operation and better material handling.
• Extended open time: Allows for longer working periods without compromising quality.

Applications in Diverse Industries

Construction Materials

HPS is widely used as an adhesive, coating, or organic liquid in various construction applications. It serves as an additive for (cement, gypsum, lime, and calcium-based) wall putty and decorative mortars. Its role as a molding adhesive for ceramic and porcelain products, along with its function as a thickener and stabilizer in aqueous solutions, makes it indispensable in construction. For example, in tile adhesives, HPS improves sag resistance and ensures a smooth application process.

Hydroxypropyl starch is a core component of HPS, contributing to its versatility in industrial applications.

Textile Industry

In the textile industry, HPS acts as a warp size, enhancing wear resistance and weaving efficiency. Its high substitution degree makes it an effective thickener for textile processing. By improving the durability of fabrics, HPS supports the production of high-quality textiles while reducing waste and rework.

Daily Chemicals and Cosmetics

HPS functions as a binder, suspending agent, and thickener in daily chemical products and cosmetics. Its ability to stabilize emulsions and suspensions ensures product consistency and longevity. For instance, in skincare formulations, HPS helps maintain the uniformity of active ingredients, enhancing the user experience.

Hydroxypropyl starch's role as a suspending agent is critical in cosmetic formulations.

Oil Drilling Industry

In oil drilling, HPS stabilizes boreholes and improves drilling conditions by reducing sloughing and flocculating cuttings. This application enhances drilling efficiency and safety, making HPS a valuable additive in the petroleum sector.
