High Viscosity Polyanionic Cellulose (PAC) is a sophisticated cellulose derivative with a unique molecular structure that underpins its valuable industrial properties. Understanding these scientific characteristics is key for R&D scientists and product formulators looking to leverage its capabilities. As a dedicated manufacturer and supplier in China, we provide PAC with precisely controlled properties for demanding applications.

The fundamental structure of PAC involves carboxymethyl groups (-CH2-COONa) attached to the hydroxyl groups of cellulose chains. The 'high viscosity' designation refers to the polymer's molecular weight and its degree of substitution (DS), which together dictate the viscosity of its aqueous solutions. A higher molecular weight and optimal DS result in significantly increased solution viscosity compared to lower viscosity grades. This property is fundamental to its function as a thickening agent.

As a polyelectrolyte, PAC molecules carry negative charges in aqueous solutions, contributing to their solubility and interaction with other charged species. This anionic nature is crucial for its performance in applications like oil and gas drilling fluids, where it helps stabilize clay particles and control fluid loss by forming a protective barrier.

Water retention is another paramount property of PAC, directly linked to its hydrophilic nature and ability to bind water molecules. This makes it invaluable in construction materials, where it prevents rapid water evaporation, allowing for proper cement hydration and improved strength development. For formulators aiming to buy PAC, ensuring the correct viscosity and water-binding capacity is essential.

The stability of PAC across a range of temperatures and salt concentrations further enhances its industrial utility. Unlike some other thickeners, it maintains its rheological properties under challenging conditions, making it a reliable chemical auxiliary. Its film-forming capability, where it creates a coherent, flexible film upon drying, is beneficial in paper and textile applications.
