HPS - Hydroxypropyl Starch Ether

Hydroxypropyl starch ether is widely employed as a thickening agent in mortar, primarily to enhance its sag resistance, lower the adhesion of wet mortar, and prolong the opening time. Frequently, it is used in conjunction with hydroxypropyl methylcellulose, being a cost-efficient alternative that can partially replace pricier additives. Even in minimal amounts, it can deliver a robust thickening effect, enhancing the workability of dry-mix mortars, preventing knife drag, and promoting better adhesion to the substrate.

The recommended dosage of HPS ranges from 0.1% to 0.2% (0.05-0.1), necessitating a reduction of hydroxypropyl methylcellulose (HPMC) by about 0.1% to 0.2% (0.1) from the original formula. Essentially, replacing 20% to 30% of HPMC with HPS in the original mix can boost construction performance and cut production costs by around 10% to 20%.

Detailed Overview of Hydroxypropyl Starch Ether (HPS)

 

Essential Information on Hydroxypropyl Starch Ether (HPS):

Chemical Name (Chinese): Hydroxypropyl Starch Ether | Chemical Name (Foreign): Hydroxypropyl Starch Ether | Abbreviation: HPS

The Chuangyao brand of hydroxypropyl starch ether is made from natural plants, modifying through a high etherification process and spray drying, resulting in a fine, white powder without any plasticizers. It's completely distinct from conventional or modified starch.

Chuangyao's hydroxypropyl starch ether is an etherified starch formed by the etherification of propylene oxide and starch, replacing the hydroxyl group in the polymer structure of starch. Its physical properties include being a white, fine powder with good fluidity and water solubility, producing a clear, colorless solution with excellent stability. It's stable against acids and alkalis, has a lower scorching temperature than original starch, and exhibits more stable viscosity changes with temperature variations. Salt and sucrose do not impact its viscosity, and post-etherification, the stability and transparency in freezing conditions improve.

Main Uses:

In the building materials sector, hydroxypropyl starch ether plays a significant role. With the evolution of the construction and building materials industry in China, especially advancements in energy-saving and insulation, external wall insulation has become a mandated national standard. Cellulose ether is indispensable in dry-mix mortar products for insulation. Chuangyao's hydroxypropyl starch ether acts as a performance enhancer of cellulose ether products, offering superior thickening effects and medium viscosity water retention with lesser amounts. It improves construction performance, ensures smoother application, and extends the material's opening time.

Chuangyao's HPS is also suitable as a binder, suspending agent, and thickener in paper, textile, petroleum drilling, and daily chemical industries.

Packaging, Storage, and Transportation:

The product is packed in moisture-proof, plastic-coated polypropylene woven bags (available in both Chinese and English) with polyethylene film lining. Each bag's net weight is 25kg. During storage and transportation, take precautions to protect the product from sunlight, rain, and moisture.
