Hydroxypropyl Starch Ether - Pengze Technology | Construction Additive & Cosmetics Application

Introduction to Hydroxypropyl Starch Ether

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 a valuable additive in various industries. This article explores the features, technical specifications, applications, and company background of HPS, highlighting its role in modern industrial processes.

Key Features and Benefits

Hydroxypropyl starch ether is engineered to deliver exceptional performance in diverse applications. Its unique properties include:

• Fast Thickening Ability: The product exhibits rapid thickening, making it ideal for applications requiring quick viscosity adjustment.
• Medium Viscosity and Water Retention: It maintains a balanced viscosity while ensuring adequate water retention, enhancing workability and reducing cracking risks.
• Low Dosage Requirement: With a recommended dosage of 0.3-0.5%, HPS achieves significant performance improvements with minimal addition.
• Enhanced Sag Resistance: Particularly effective in tile adhesives and wall putties, it prevents sagging and improves structural stability.
• Improved Workability: The additive ensures smoother application processes, reducing labor intensity and material waste.
• Extended Open Time: It prolongs the working time of materials, allowing for more flexible construction and application schedules.

Technical Specifications

Applications in Key Industries

Construction Materials

Hydroxypropyl starch ether is widely used in the construction industry as an additive for cement-based and lime-calcium-based putty products and mortars. It improves workability, ensures smooth construction, and reduces the need for cellulose ether. When combined with methyl cellulose ether, it enhances thickness, internal structure, and crack resistance. It is recommended for various wall putty powders and mortars, including gypsum-based, cement-based, and lime-calcium-based systems.
