Polyanionic cellulose.
Rosfloc SAND is a polyanionic cellulosic polymer that is used to control the filtration characteristics of drilling fluids.
Application
High-viscosity / low-viscosity polymer is used to control the filtration and rheological properties of water-based drilling fluids, primarily as a thickening agent. Provides additional viscosity and promotes the formation of a strong filter cake, preventing filtration into the rock.

Safety requirements
According to acute toxicological characteristics, Rosfloc SAND refers to the 4th class of hazard Ц low-hazard chemical substances as per GOST standard 12.1.007-76. It poses no hazard of acute inhalation intoxication. In case of contact it irritates conjunctiva and skin cover. Rosfloc SAND is fire-flame-proof.
Transportation
Rosfloc SAND is transported by all the type transport according to the rules of cargo transportation.
