Sodium Carboxymethyl Cellulose CMC for petroleum drilling: well mud is the necessary condition while drilling. Mud’s gravity, viscosity, thixotropic property and water-loss amount change according to area, depth of well and different mud. CMC can readjust these data while used in mud.

Carboxymethyl Cellulose - HV
Appearance:cream color,free flowing powder
Sodium CMC Content on dry basis ---------- min.65%
Moisture --------------------------------- max.8%
Degree of substitution -------------------- 0.7 TO 0.8
PH 1% SOL --------------------------------- 7 - 9
Viscosity in 2% sol.on brook field -------- 500-1000cps
