Hydroxypropyl starch ether
1. Chemical name: hydroxypropyl starch ether
2. English abbreviation: HPS
Hydroxypropyl starch ether is a white powder obtained from natural plants after modification, highly etherification reaction, and then spray drying, without plasticizers. It is completely different from ordinary starch or modified starch. Hydroxypropyl starch ether combined with hydroxypropyl methyl cellulose ether can play a role in thickening, lubricating, improving construction, promoting internal structure, with better crack resistance, improve workability. The addition of hydroxypropyl methyl cellulose can be significantly reduced by adding hydroxypropyl starch ether.

Application characteristics of hydroxypropyl starch ether:
● Provides very good rapid thickening ability; Medium viscosity, high water retention;
● Small dosage, very low filling amount can achieve a high effect;
● Can be used with methyl cellulose (MC) or hydroxypropyl methyl cellulose (HPMC) to reduce the use of cellulose ether;
● Improve the overall anti-slide ability of the material, so that the material does not slide down (slip) flow when applying or pasting other materials;
● It has good lubricity, which can improve the operation performance of the material and make the operation smoother.
● Extended opening hours for materials
● All kinds of (cement, gypsum, lime calcium base) interior and exterior putty.
● All kinds of finishing mortar plastering mortar.
Hydroxypropyl starch ether is recommended for use in the following materials:
1, all kinds of (cement, gypsum, lime calcium base) inside and outside wall putty powder;
2, all kinds of (ceramic tile, stone) binder;
3, all kinds of finishing mortar and plastering mortar.
4, all kinds of gypsum, ceramics and porcelain products as a forming adhesive, low ash, good viscosity
5, in papermaking, textile, oil drilling, daily chemical industry as an adhesive, suspension agent and thickener application.
Packaging and storage of hydroxypropyl starch ether
The product is packaged in plastic-coated polypropylene woven bag, net weight per bag: 25kg;
