Hydroxypropyl starch ether(HPS) is a kind of irregular flake white powder, avirulent,

insipid, soluble in cold water, forming a transparent or translucent viscous liquid. It has

the ability of thickening, adhesion, dispersion, emulsion, suspension and water retaining.

HPS can be used as building materials of adhesive, coating or organic liquid gels. 

Physical Properties 

Stable to acid, alkali, lower than the original starch gelatinization temperature, cold and hot

viscosity changes from the original starch and stability. Mixed with salt, sugar, etc for viscosity

has no effect. After etherification, freeze-thaw stability and transparency were improved.

Advantages and application 

1. Low provide very good fast thickening ability; Medium viscosity, higher water retention
2. Small dosage, low add quantity can achieve a high effect
3. With methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC) cooperate to use, reduce the use amount of cellulose ether
4. To improve the whole material of sag resistance, make the material or other material paste daub (slide) flow down
5. Has good lubricity, can improve the performance of material, make the operation more smoothly
