(Hydroxyl Ethyl Cellulose)


DX-HEC MV is a medium viscosity hydroxyl ethyl cellulose ether designed for use as a viscosifier in brines and saline fracturing fluids, workover fluids, completion fluids and drilling fluids.

It gives pseudoplastic rheology but essentially no gel strength development.

It can thicken, suspend, bind, emulsify, form films, stabilize, disperse, retain water, and provide protective colloid action.

It is a free-flowing powder that readily dissolves in hot or cold water without excessive mixing or heating.
