SPECIFICATION OF POLYANIONIC CELLULOSE<br />
Product Name: <strong>Polyanionic</strong> cellulose (PAC)<br />
CAS No.: 9004-32-4<br />
H.S. Code: 39123400<br />
Synonyms: Poly anioniccellulose, PAC<br />
Molecular Formula: [C6H7O2(OH)2OCH2COONa]n<br />

Description:<br />
<strong>Polyanionic</strong> <strong>Cellulose</strong>, called PAC for short, is water-solubility cellulose ether derivatives under chemically modifying<br />
from natural cellulose. <strong>Polyanionic</strong> cellulose is a kind <strong>of</strong> important water-solubility cellulose ether and usually applied<br />
as its sodium salt. It is white or slightly yellow powder, non-toxic and tasteless.<br />

Usage: <strong>Polyanionic</strong> cellulose can be dissolved in water, owns good heat resistance and salt tolerance, as well as<br />
strong antibacterial property. The mud fluid compounded by <strong>Polyanionic</strong> <strong>Cellulose</strong> owns good water loss control,<br />
ejection capability and high temperature tolerance. <strong>Polyanionic</strong> <strong>Cellulose</strong> is widely used in oil drilling, especially in<br />
salt water based drilling fluids, seawater based drilling fluids and saturated-brine drilling fluids.<br />
Storage and Transportation:<br />
1. <strong>Polyanionic</strong> cellulose should be Moisture-pro<strong>of</strong>, fire prevention, anti-high temperature, store in ventilate and<br />
dry environment.<br />
2. <strong>Polyanionic</strong> cellulose should prevent raining during transportation, prohibit using cleek during loading and<br />
unloading.<br />
3. <strong>Polyanionic</strong> cellulose should prevent moisture during storage, or the product can be gelatinized or partially<br />
dissolved to influence applications.<br />
