Product overview

The starch was chemically modified to increase the hydration group, and the starch particles were physically modified by the synergistic action of high temperature and solvent to improve the water solubility of the product. And by adding heat stabilizer, the introduction of high temperature resistance of modified group, its ability to resist temperature is up to 140 ℃. The product has good filtration loss effect in low temperature and high temperature conditions, which is adapted to various temperature conditions, and easy to dissolve, ultra-low viscosity, salt resistance to saturation and other advantages.
