HT starch using starch as the main body, to increase hydration groups by carboxy methylation, also with the coordinated effect of high temperature and solvent ,to modify physical property of starch granules, to improve the water solubility of the product, and add high temperature stabilizer, so the temperature resistance capacity can be up to 150℃. At the same time ensure its good fluid loss performance under the condition of low temperature.HTHP starch is an environmental friendly filtration reducer. Its common dosage is 1%-2%.
