Hydroxypropyl starch ether HPS

 

Hydroxypropyl starch ether (HPS)

essential information:

Chinese name of Chemistry: hydroxypropyl starch ether, foreign name of Chemistry: hydroxypropyl starch ether, abbreviated as HPS.

Chuang Yao brand hydroxypropyl starch ether (HPS) is a white fine powder obtained from natural plant as raw material after modification, high etherification reaction and spray drying. It does not contain plasticizer. It is totally different from ordinary starch or modified starch.

Chuangyao brand hydroxypropyl starch ether is a kind of etherified starch, which is formed by etherification of propylene oxide and starch, replacing the hydroxyl group in the polymer structure of starch. Physical properties: White (colorless) powder, good fluidity, good water solubility, transparent colorless water solution, good stability. It is stable to acid and alkali, and its scorching temperature is lower than that of the original starch, and its cold and hot viscosity changes are more stable than that of the original starch. Mixing with salt and sucrose had no effect on viscosity. After etherification, the stability and transparency of ice melting are improved. Chemical properties: the properties of starch derivatives with hydroxypropyl substituents. There are three replaceable hydroxypropyl groups in the glucose unit of starch, so products with different degrees of displacement can be obtained.

Technical indicators:


Main purpose:

Hydroxypropyl starch is used for building materials. With the development of construction and building materials industry in China, especially the development of energy-saving and heat preservation of buildings, the external insulation of external walls has become a national compulsory standard. The dry mixed mortar products for heat preservation cannot be separated from cellulose ether. Chuangyao brand hydroxypropyl starch ether, as the performance improver of cellulose ether products, has good thickening effect and good water retention of medium viscosity It has the advantages of less addition, better construction performance, smoother operation and longer opening time of materials.

Chuangyao brand HPS can also be used as binder, suspending agent and thickener in papermaking, textile, petroleum drilling, daily chemical industry and other industries.

Packaging, storage and transportation:

The product is packed in plastic coated polypropylene woven bags (Chinese characters or English characters) with moisture-proof lining polyethylene film. The net weight of each bag is 25kg. During storage and transportation, the product is protected from sun, rain and moisture.
