Our high-performance Hydroxypropyl Starch Ether (HPS) is a premium, highly etherified white fine powder derived from natural plant sources. Specifically engineered as a high-efficiency additive for the construction industry, it serves as an essential component in cement-based, lime-calcium-based, and gypsum-based putty and mortar products. Free from plasticizers, HPS ensures a sustainable and eco-friendly solution for modern building materials.
Designed for optimal synergy, this product exhibits excellent compatibility with other building admixtures. When used in conjunction with methyl cellulose ether, it significantly enhances internal structure, increases thickness, and provides superior resistance to cracking and sagging. From improving workability to extending open time, our HPS is the professional choice for achieving a smooth, durable, and high-quality finish in both internal and external wall applications.

Frequently Asked Questions
HPS provides rapid thickening, improves anti-slide ability, and extends open time, ensuring the joint powder is easier to apply and less prone to cracking.
While HPS is effective on its own, using it in conjunction with methyl cellulose ether can significantly increase thickness and improve internal structural resistance.
The recommended dosage is generally between 0.3-0.5%o, although we advise buyers to conduct specific tests to determine the ideal dosage for their unique formulation.
Yes, HPS is highly recommended for both internal and external wall putty powders and various types of decorative mortars.
In oil drilling, it helps stabilize the borehole and improves drilling conditions by providing anti-sloughing and preventing the flocculation of cuttings.
High etherification improves the solubility and stability of the starch in water, leading to better thickening and suspension properties in the final product.
