Our high-performance HPS (Hydroxypropyl Starch Ether) is a premium, modified etherified starch derived from natural plant raw materials. Engineered as a sustainable and efficient additive, this white fine powder is completely free from plasticizers, making it an environmentally friendly choice for modern construction materials. Specifically optimized for gypsum joint powders and cementitious mortars, HPS provides exceptional structural stability and compatibility.
When utilized as an admixture in cement-based, lime-calcium-based putty, or gypsum-based products, HPS significantly enhances workability and construction efficiency. By synergizing with methyl cellulose ethers, it optimizes internal structures to deliver superior crack resistance and sag resistance. This high-quality starch ether not only improves the overall application experience but also allows for a strategic reduction in the volume of expensive cellulose ethers without compromising performance.
