"Hydroxypropyl starch is an organic substance with the chemical formula CHO·x, which is a white or light white powder with no special odor. Insoluble in cold water, gelatinized under heating conditions into a viscous colloid with certain transparency, good stability. Hydroxypropyl starch is one of the most widely used modified starch in food industry. The properties of starch paste can be improved effectively by introducing a certain amount of hydroxypropyl to starch molecules. On the one hand, hydroxypropyl can produce steric hindrance effect, preventing the aggregation and crystallization of starch chains; On the other hand, hydrophilicity of hydroxypropyl group can weaken the internal hydrogen bond strength of starch particle structure, make it easy to expand and gelatinize, and the resulting starch paste has high transparency and strong fluidity.

Purpose:

1) Hydroxypropyl starch Food industry, hydroxypropyl starch can be used as a thickening agent, hydroxypropyl starch can be used as a suspension agent, hydroxypropyl starch can be used as a binder.

2) Hydroxypropyl starch paper industry: hydroxypropyl starch is used as internal sizing of paper, hydroxypropyl starch is used as surface sizing, hydroxypropyl starch makes printing ink bright, hydroxypropyl starch makes uniform, hydroxypropyl starch makes the film smooth, hydroxypropyl starch reduces ink consumption, hydroxypropyl starch and has a certain ability to pull wool.

3) Hydroxypropyl starch textile industry: hydroxypropyl starch can be used as warp paste, hydroxypropyl starch to improve weaving wear resistance, hydroxypropyl starch and weaving efficiency, hydroxypropyl starch with high degree of substitution can be used as printing paste.

4) hydroxypropyl starch pharmaceutical industry: hydroxypropyl starch can be used as a disintegrator of tablets, and hydroxypropyl starch can also be used as a plasma increment agent.

5) Hydroxypropyl starch stabilizes well wall, hydroxypropyl starch improves borehole conditions, hydroxypropyl starch prevents collapsing, hydroxypropyl starch flocculates drilling cuttings, etc.

6) Hydroxypropyl starch daily chemical industry: hydroxypropyl starch in daily chemical industry and hydroxypropyl starch in cosmetics or coatings with adhesives, suspension agents and thickeners.

7) hydroxypropyl starch In addition, hydroxypropyl starch can also be used as a binder for building materials, hydroxypropyl starch coatings or gel agents for organic liquids, hydroxypropyl starch.

8) Food industry: can be used as adhesive, thickener, suspension agent, increase stability.
