Hydroxypropyl Starch Ether - Pengze Technology | Construction, Cosmetics, Daily Chemicals

Hydroxypropyl starch ether (HPS) is a high-performance, modified starch derivative that has gained significant attention in the construction, cosmetics, and daily chemical industries. This white fine powder, derived from natural plant materials through a highly etherified reaction, offers exceptional properties such as rapid thickening, water retention, and compatibility with various building admixtures. Its unique characteristics make it an indispensable component in applications ranging from cement-based mortars to textile coatings and oil drilling fluids.

Product Overview

Hydroxypropyl starch ether is a modified starch derivative produced through a chemical process that introduces hydroxypropyl groups into the starch molecule. This modification enhances its solubility, stability, and functional performance. Unlike conventional starch, HPS is free from plasticizers and is designed to improve the workability and durability of construction materials. Its versatility is evident in its wide range of applications, including wall putty, mortar, and industrial coatings.

Key Features and Advantages

• Fast Thickening Ability: Hydroxypropyl starch ether exhibits excellent rapid thickening properties, ensuring improved workability and reduced slippage in construction materials.
• Medium Viscosity and Water Retention: The product maintains a balanced viscosity while retaining moisture, which enhances the stability of mortars and putties.
• Low Dosage, High Efficiency: With a recommended dosage of 0.3-0.5%, HPS delivers significant performance improvements without excessive usage.
• Enhanced Crack and Sag Resistance: When combined with methyl cellulose ether, it strengthens the internal structure of materials, reducing cracks and sagging.
• Extended Open Time: The additive prolongs the working time of materials, allowing for more efficient application and adjustments during construction.
