Hydroxypropyl Starch Ether - Pengze Technology | Applications, Specifications

Product Overview

Hydroxypropyl starch ether is produced through a chemical modification of natural starch, resulting in a material with enhanced functional properties. Unlike traditional starches, this etherified derivative exhibits superior compatibility with other building admixtures, making it an ideal choice for cement-based and lime-calcium-based putty products and mortars. The product's unique structure allows it to improve workability, reduce the need for cellulose ether, and provide excellent crack resistance and sag resistance.

Key Features and Advantages

• Fast Thickening Ability: Hydroxypropyl starch ether provides rapid viscosity increase, ensuring efficient performance in applications requiring immediate thickening.
• Medium Viscosity with Water Retention: The product maintains a balanced viscosity while retaining water, which is crucial for maintaining workability in construction materials.
• Low Dosage Requirement: With a recommended dosage of 0.3-0.5%, this additive achieves significant performance improvements with minimal usage, reducing costs and waste.
