Lignosulfonate Dispersant
JUMP TO
GENERAL DESCRIPTION
RiSperse-150 is a high-efficiency lignosulfonate dispersant formulated for water-based drilling fluids. It effectively controls solids, prevents particle agglomeration, and enhances suspension of weighting materials, minimizing settling and improving overall mud stability. Its excellent solubility, combined with thermal and chemical stability, ensures consistent performance in high-temperature and high-salinity environments. RiSperse-150 also optimizes rheology and viscosity profiles, supporting smoother circulation and efficient drilling operations.
