HEC HV
Product Name: Hydroxyethyl cellulose High viscosity oil drilling grade
CAS NO.:********0
Typical Physical Properties
Our HEC HV is a non-ionic water-soluble polymer designed specifically to increase the viscosity of water-based fluids used in drilling,workover and completion operations.The resulting polymer solutions are clear,viscous and residue-free.
Appearance Off-white free flowing powder
Mole substitution degree,M.S 1.**3.0
Solution viscosity,cps* ********0
Moisture content,% max. *0.0
pH,1% solution 6.**8.0
Bulk density(kg/m3) ******0
*Measured by Brookfield viscometer,at *5oC,1% aqueous solution
Application
EcoFluid C****0 is used to viscosity single salt CaCl2 brines and all mono-valent-salt brines such as NaCl,NaBr,KCl,KBr,and NH4Cl.
Oilfield fluids containing HEC exhibit high apparent viscosity,high yield point and low fragile gel strength.Its shear-thinning behavior known as pseudoplasticity help both increase penetration rates under high shear and provide excellent suspending action for optimum hole cleaning under low shear while viscosity is regained.
Packaging:
Packed in *5 kgs or *0 lbs paper sacks.
