PolySR starch reagent

PolySR starch reagent is designed for regulation of filtration characteristics and stabilization of process fluids used in drilling.
The range of starch reagents includes the following grades:PolySR-F with increased resistance to Ca and Mg salts.
PolySR-K which effectively reduces the filtration value.
PolySR-D with decreased viscous propertiesPolySR-O is an organophilic starch with hydrophobic properties.
