HTHP polymer viscosifier Risol-Htvis

Product Description
Ht-vis, white power, is AMPS type high temperature salt-resistant copolymer. This product has a very good property to improve the viscosity in drilling fluid. It could resist 180 deg.C and could resist saturated salt water. it could evidently improve the viscosity in freshwater, seawater, salt water drilling fluid system; ht-vis could apply to deep wells and ultra deep wells, especially non-solid phase drilling fluid system. Ht-vis also could reduce the fluid loss.
