Polyanionic Cellulose HS Code 39123100

Nourisi ®Polyanionic Cellulose HS Code 39123100, is a water-soluble anionic polymer derived from natural cellulose through chemical modification. It appears as a cream white to off-white, free-flowing powder that is odorless, non-toxic, and readily soluble in both cold and hot water.

Polyanionic Cellulose HS Code 39123100 is produced by introducing carboxymethyl groups onto the cellulose backbone, creating a sodium salt form with a high degree of substitution (DS ≥ 0.9). This modification gives PAC much better salt tolerance, thermal stability, and filtration control than conventional Carboxymethyl Cellulose (CMC).

1. Oil & Gas Drilling Fluids

Polyanionic Cellulose HS Code 39123100 is widely used as a fluid loss control agent and viscosifier in water-based drilling fluids. It forms a thin, low-permeability filter cake on the borehole wall, reducing filtrate invasion and protecting permeable formations.

Key functions include:

● Fluid loss control in freshwater, seawater, and brine systems

● Shale inhibition by encapsulating drill solids

● Rheology modification for better hole cleaning

● Compatibility with workover, completion, and fracturing fluids

 

Research shows that combining PAC-L and PAC-R at around 0.7 wt% can deliver superior filtration performance through synergistic effects.

 

2. Construction Industry

In construction, PAC acts as a water retention agent and workability enhancer in cement, mortar, and gypsum-based products. It helps ensure complete binder hydration, reduces cracking from rapid drying, and improves the consistency of tile adhesives, plasters, and self-leveling compounds.

 

3.Other Industrial Uses

 

Nourisi ®Polyanionic Cellulose HS Code 39123100 performs well in demanding environments. It is soluble in fresh water, seawater, and brine systems, making it suitable for offshore and deep-well operations. It maintains stability in high-salinity conditions and at elevated temperatures, up to 150°C with proper formulation.

PAC also resists bacterial fermentation, so it does not require preservatives in most applications. Its shear-thinning behavior improves pumping efficiency while maintaining solids suspension when shear is reduced. As a cellulose derivative, PAC is biodegradable and environmentally friendly.

Nourisi ®Polyanionic Cellulose HS Code 39123100 conforms to API 13A. However, we recommend that the user ensure that this product is in compliance with the local regulations in force, particularly in the country where the product is to be consumed.
