Chrome Free Lignosulphonate
Chrome-Free Lignosulphonate (CFLS) is a high-performance, environmentally acceptable drilling fluid additive derived from sulfonated lignin, processed without using chromium salts. It acts primarily as a thinner/deflocculant, rheology stabilizer, and HTHP fluid conditioner for water-based drilling fluids. CFLS is widely used in modern drilling operations because of its low environmental impact, high temperature stability, and excellent dispersing ability.
