Hydroxypropyl Starch Ether (HPS) is an eco-friendly, water-soluble polymer derived from natural starch through etherification modification. Renowned for its exceptional thickening, water retention, and workability-enhancing properties, HPS serves as a versatile additive in dry-mix mortars, tile adhesives, gypsum-based plasters, and other construction materials.
Product Introduction
Hydroxypropyl Starch Ether (HPS) is an eco-friendly, water-soluble polymer derived from natural starch through etherification modification. Renowned for its exceptional thickening, water retention, and workability-enhancing properties, HPS serves as a versatile additive in dry-mix mortars, tile adhesives, gypsum-based plasters, and other construction materials. It elevates product performance while aligning with global green building initiatives.
HPS Key Benefits
✅ Superior Water Retention
Slows water evaporation to ensure complete cement hydration, minimizing cracks and voids for durable structures.
✅ Enhanced Workability
Optimizes rheological properties, improves lubrication, and reduces application effort, boosting on-site efficiency.
✅ Anti-Sagging Performance
Enables stable vertical application and thick-layer coating without slump, ideal for both thin renders and heavy-duty leveling.
✅ Eco-Conscious Solution
Sourced from renewable starch, non-toxic, and fully compliant with international green building standards (e.g., LEED, BREEAM).
✅ Broad Compatibility
Synergizes seamlessly with cellulose ethers, redispersible polymer powders, and other additives for flexible formulation design.
