Polymer Oilfield Chemicals Polymer salt tolerance for Fluid Loss ControlPolymer Polymer additive with white to light-yellow appearance was polymerized by heat resistance and salt tolerance allyl monomers. It provides better rheology regulation and fluid loss control.
Polymer has some advantages as follows:
low viscosity effect in mud by special molecular structure;
superior function in fresh mud and brine mud;
Better heat resistance in fluid loss system;
Perfect anti-sloughing and clay hydration control performance.
