Products Description


1. Hydroxypropyl starch ether (HPS) is a white fine powder obtained from natural plants as raw materials, through modification, high etherification reaction, and then spray drying. It does not contain plasticizers. It is completely different from ordinary starch or modified starch.

2. Preparation method: Hydroxypropyl starch is a kind of chemically modified starch. It is etherified by propylene oxide and starch to replace the hydroxyl group in the starch polymer structure to become an etherified starch.

3. Physical properties: white (colorless) powder, good fluidity, good water solubility, its aqueous solution is transparent and colorless, and has good stability. It is stable to acid and alkali, the melting temperature is lower than that of native starch, and the change of viscosity between cold and hot is more stable than that of native starch. Mixing with salt, sucrose, etc. has no effect on viscosity. After etherification, ice melting stability and transparency are improved.

4. Chemical properties: the properties of starch derivatives with hydroxypropyl substituents. The glucose unit of starch has 3 hydroxypropyl groups that can be replaced, so products with different degrees of substitution can be obtained.

5. Technical indicators Appearance: white powder, easy to absorb moisture

Solubility: can be dissolved in water and become a transparent solution
Viscosity (5% aqueous solution, 20°C): 500-20000 mPa.s
PH value (2% aqueous solution): 8-10.5
Application characteristics:
  1. Very good rapid thickening ability; medium viscosity, with certain water retention;
   2. The dosage is small, and the extremely low dosage can achieve high results;
  3. Improve the anti-sliding ability of the material;
  4. Improve the operation performance of the material and make the operation smoother.
   5. Extend the opening time of materials;
