In industrial manufacturing, leaps in efficiency and product performance often start with innovating basic materials. By modifying natural starch with precision etherification to add hydroxypropyl groups, industrial-grade hydroxypropyl starch ether (HPS) was born. It’s no longer a run-of-the-mill raw material—but an indispensable high-performance “booster” that elevates formulations across multiple industries.
Unlike food or pharmaceutical-grade starch ethers, industrial-grade HPS’s core strengths lie in its exceptional stability and robust functionality. It thrives in harsh industrial environments and delivers measurable improvements to end-product quality, making it a go-to additive for manufacturers worldwide.
HPS’s versatility shines in key industrial sectors, solving critical formulation and production challenges:
In dry-mix mortars, tile adhesives, wall putties, and gypsum plasters, HPS pulls double duty to boost performance and workability:
Superior water retention: It locks in moisture, preventing porous substrates from siphoning water away too quickly or evaporation from drying out the mix. This ensures full cement hydration, the foundation for stronger final strength and crack-free surfaces.
Smooth thickening & lubrication: It delivers a user-friendly application feel, extends the product’s open time for adjustments, and stops slurry from sagging on vertical surfaces—cutting rework and raising construction quality and efficiency.
As a naturally derived thickener, HPS is a cost-effective solution for coating formulations:
It regulates viscosity to prevent pigment and filler settling or clumping, preserving storage stability and a consistent, smooth texture when the can is opened.
When paired with synthetic thickeners, it creates a synergistic effect that optimizes formulation costs without sacrificing performance.
The strong, water-soluble film it forms simplifies post-production desizing, making the process more efficient and environmentally friendly.
Its excellent film-forming properties boost yarn strength and smoothness, directly improving the overall quality of finished textiles.
Added to pulp, it strengthens fiber-to-fiber bonding, boosting the paper’s physical durability (like tear and tensile strength).
Used as a surface sizing agent, it elevates the paper’s grease resistance and printability, making it more suitable for high-quality packaging and printed materials.
Customizable performance: Manufacturers can tweak HPS’s production process to match specific industry needs—such as target viscosity, water retention levels, or dissolution speed—delivering tailored solutions for unique challenges.
Strong cost-effectiveness: HPS matches the performance of many synthetic polymers but is sourced from renewable starch. It lowers formulation costs while maintaining quality, a win for budget and sustainability goals.
Eco-friendly profile: Its biodegradability aligns with strict global environmental regulations and the growing demand for sustainable manufacturing practices, reducing a brand’s carbon footprint.
Industrial-grade HPS is a perfect example of how modern chemical engineering can transform natural materials into high-impact industrial solutions. It proves that balancing efficiency, functionality, and sustainability is achievable through smart material design.
