Hydroxypropyl Starch Ether (HPS) is a premium, highly etherified white fine powder derived from natural plant sources. Engineered without the use of plasticizers, this modified starch ether serves as a high-performance admixture for cement-based, lime-calcium-based putty, and various mortar products. Its exceptional compatibility with other building admixtures makes it an essential component for modern construction materials.
By integrating HPS into your formulations, you can significantly enhance workability and internal structure while reducing the overall consumption of cellulose ethers. Whether used for internal and external wall putty or decorative mortars, HPS provides superior crack resistance, prevents sagging, and optimizes the operational performance of the material for a smoother application process.

Frequently Asked Questions
It is primarily used in construction as an additive for wall putty (cement, gypsum, lime base), tile adhesives, and decorative mortars, as well as in the textile industry as a warp size or thickener.
HPS can be used in conjunction with methyl cellulose ether to reduce the total amount of cellulose ether required while maintaining or improving thickness and crack resistance.
The recommended dosage is typically between 0.3% and 0.5%. However, we advise buyers to conduct their own tests to determine the specific dosage for their unique application.
Yes, our HPS is obtained from natural plant raw materials and does not contain plasticizers, making it a sustainable choice for the chemical additive industry.
Absolutely. In textiles, it serves as a warp size to increase wear resistance and weaving efficiency, and high substitution degrees can be used as a thickener.
We offer 25kg bags and 600kg pallets with OEM support. Shipping is worldwide via CIF, FOB, and CFR terms directly from our factory.
