Oil Drilling Grade Hydroxyethyl Cellulose is a non-ionic water-soluble polymer derived from cellulose. This is widely used in various industries such as food, pharmaceuticals, cosmetics, and oil drilling. It is a high-purity, high-viscosity polymer that is used to control the rheology of drilling fluids. The offered range helps to reduce fluid loss by forming a thin, impermeable filter cake on the formation face, which helps to maintain the integrity of the drilling fluid. Oil Drilling Grade Hydroxyethyl Cellulose is an important additive in the oil drilling industry that helps to improve the efficiency and safety of drilling operations.
