PAC-HV (Polyanionic Cellulose)
This product has been discontinued and removed from our shelves.
PAC-HV is a high-viscosity sodium salt of carboxymethyl cellulose, and it is commonly referred to as polyanionic cellulose (PAC).
Application
This oilfield chemical is an efficient water-soluble polymer to reduce the API filtration rate of diverse kinds of drilling fluids, such as freshwater, seawater, saturated saltwater, solids-free brine, native mud, flocculated mud, inhibited mud, contaminated system, etc.
On the other hand, our polyanionic cellulose is able to develop high viscosity for drilling fluids, thus providing enhanced hole cleaning and suspension properties under different fluid conditions.

Safety and Handling
For safety considerations, personal protective equipment is highly recommended and actually it is a must. Before work, please refer to the precautions illustrated in the MSDS.
Packaging and Storage
PAC-HV is packed in 25kg (50lb) paper sacks.
The container should be closed, and then placed at a dry, well-ventilated area that is away from heat, sparks, flames and incompatible materials. For palletizing, banding, shrink-wrapping and stacking operations, please follow safe warehousing practices.
