HPS
PTMA
3505100000
Hydroxypropyl starch ether (HPS) is a white fine powder derived from natural plants.
HPS is a chemically modified starch, which is etherified by propylene oxide and starch to replace the hydroxyl group in the starch macromolecule structure to become an etherified starch.
Physical Properties
White (colorless) powder with good fluidity and good water solubility.
Its aqueous solution is transparent and colorless with good stability.
HPS is stable to acid and alkali, the sintering temperature is lower than that of native starch, and the change of hot and cold viscosity is more stable than that of native starch. Mixing with salt and sucrose has no effect on viscosity. After etherification, both ice-melt stability and transparency were improved.
Chemical Properties
Due to the properties of starch derivatives with hydroxypropyl substituents, the glucose unit constituting starch has 3 hydroxypropyl groups that can be replaced, so products with different degrees of substitution can be obtained.
Technical Data
Appearance: white powder, easy to absorb moisture
Solubility: Can dissolve in water and become a transparent solution
Viscosity (5% aqueous solution, 20℃): 500-20000 mPa.s
PH value (2% aqueous solution): 8-10.5
Application
(1) food industry, hps can be used as a thickening agent, can be used as a suspending agent, and hps can be used as an adhesive.
(2) paper industry: hydroxypropyl starch- hps
HP is used for internal sizing of paper, used for surface sizing, makes printing ink bright, makes uniform, makes the film smooth, hps reduces ink consumption, and has a certain ability to pull hair.
(3) textile industry: hps can be used as warp yarn size, hps can improve the abrasion resistance during weaving, weaving efficiency, hydroxypropyl starch with high degree of substitution of hydroxypropyl starch Propyl starch can be used as printing paste.
(4) pharmaceutical industry: Hydroxypropyl starch can be used as a disintegrating agent for tablets, and hydroxypropyl starch can also be used as a plasma bulking agent.
(5)stabilizes the well wall, hps improves wellbore conditions, prevents collapse, and flocculates drill cuttings.
(6)daily chemical industry: hps is used as a binder, suspending agent and thickening agent in daily chemical industry and hydroxypropyl starch in cosmetics or coatings.
(7) Construction: hps can also be used as a binder for building materials, a gelling agent for hydroxypropyl starch coatings or organic liquids, and hydroxypropyl starch.
(8) Food industry: It can be used as adhesive, thickener, suspending agent to increase stability.
