Product Name:Oil drilling grade
CAS No.: 11138-66-2
General information:
Oil drilling grade is a kind of hydrophilic biological high-fraction polysaccharide obtained from corn starch, fermented by Xanthomonas bacterium, extracted, dried and crushed into finished products. Because of its superior thickening and stabilizing effects, shear resistance and unique pseudoplastic rheological properties, it is widely used in food, medicine, fine chemicals, oil drilling and other fields.
