Modified Starch HT

Product Description

Ocean-Fil SHR-1 is modified starch by inserting hydration groups and high temperature stabilizer to improve the water solubility and temperature resistance (up to 140 ℃). And ensure its good fluid loss performance under both low and high temperature. SHR is an environmental friendly, low viscosity, salt resistance (up to saturation) filtration reducer.

Its recommend dosage is 3.0 – 7.0ppb.
