Drilling Grade - Polyanionic Cellulose, PAC
Price above is for sample ONLY, please contact customer service for bulk order quote.
General Description
PAC is a water-soluble polymer produced only from cellulose chemically reacted with carboxy-methyl (anionic) groups. The product obtained is further purified to significantly increase the active polymer content. It’s widely used in oil and gas field industry for applications of fluid loss control, viscosity and shale inhibition. PAC typically provide higher degree of substitution and purity as comparing with CMC products. The product is a freeflowing and/or granular powder.
CAS No.: 9004-32-4
Function

Applications
|
Applications |
Functions |
|
Oil and Gas Field Driling |
Performs as a filtration control agent, viscosifier, and shale inhibitor in water-based mud such as freshwater, seawater, and saturated brine system. |
|
Mining Drilling |
|
|
Horizontal Directional Drilling (HDD) |
Act as a filtration control agent; Along with bentonite, it also improves lubricity and helps to prevent bit balling; Used in more coarse-grained soils. |
|
Mining Processing |
Functions as a granular binder in the iron-ore pelletization process and flotation inhibitor in the flotation process. |
