Ferro chrome lignosulfonate:
Characteristics:
1) With excellent thinning performance, filtration control capacity and
powerful anti-electrolyte capacity
2) Effective at temperatures exceeding 150 - 160oC
3) Can also be used at temperatures above 200oC when combined
with lignite derivatives and other temperature-resisting chemicals
3) FCLS is a good emulsifier for oil in water mud

Calcium lignosulfonate (CAS no.: 8061-52-7)

Sodium lignosulfonate (CAS no.: 8061-51-6):
Sodium lignosulfonate (SLS) is a processed anionic surface agent with
satisfactory performance that is a by-product sulfite papermaking. With
powerful dispersive, water-reducing and damping actions, it is widely
used in petroleum drilling and construction applications.

Chrome lignosulfonate:
Chrome lignosulfonate is a specially prepared thinner used in drilling
fluids. Resistant to electrolytes and high temperatures, it is mainly
used for deep well drilling in complicated geological situations that
feature high electrolyte levels.
