Polyanionic cellulose (PAC) is a versatile chemical compound that finds extensive use in various industries due to its unique properties. As a leading supplier and manufacturer of chemical thickeners, Unionchem offers a range of high-quality PAC products that cater to diverse applications. In this article, we will explore the different types of polyanionic cellulose and how they vary in properties, shedding light on the benefits and uses of these products.

Types of Polyanionic Cellulose:

1. Regular PAC:

Regular PAC is the most commonly used type of polyanionic cellulose. It is derived from cellulose through a series of chemical reactions that introduce anionic groups onto the cellulose backbone. Regular PAC is known for its excellent thickening and stabilizing properties, making it suitable for a wide range of applications in industries such as oil drilling, pharmaceuticals, and food processing.

2. Low Viscosity PAC:

Low viscosity PAC is a specialized variant that offers reduced viscosity compared to regular PAC. This makes it particularly useful in applications where lower viscosity is desired, such as in certain food products and industrial processes where flow characteristics are crucial. Low viscosity PAC retains the thickening and stabilizing capabilities of regular PAC while offering specific advantages in terms of flow and handling.

3. High Viscosity PAC:

On the other end of the spectrum, high viscosity PAC is tailored to provide enhanced thickening properties, making it suitable for applications where higher viscosity levels are required. This type of PAC is often utilized in demanding industrial processes where superior viscosity control is essential for achieving desired product performance. High viscosity PAC can contribute to improved product texture, stability, and overall quality.

4. Ultra-High Viscosity PAC:

Ultra-high viscosity PAC represents the pinnacle of thickening capabilities within the polyanionic cellulose family. This specialized variant offers exceptional viscosity enhancement, making it ideal for applications that demand maximum thickening effects. Ultra-high viscosity PAC can be employed in scenarios where extreme rheological control is necessary, such as in certain drilling fluids, construction materials, and personal care products.

Variations in Properties:

The different types of polyanionic cellulose exhibit variations in several key properties, which determine their suitability for specific applications.


One of the primary distinguishing factors among various PAC types is their viscosity characteristics. Regular PAC typically offers moderate to high viscosity, whereas low viscosity PAC provides a lower viscosity profile. High viscosity and ultra-high viscosity PAC variants deliver significantly elevated viscosity levels, catering to applications that necessitate intense thickening effects.

Thickening Efficiency:

The thickening efficiency of polyanionic cellulose is influenced by factors such as molecular weight and degree of substitution. While regular PAC offers reliable thickening performance across a broad spectrum of applications, low viscosity PAC provides tailored thickening solutions for products requiring specific flow behavior. High viscosity and ultra-high viscosity PAC excel in delivering exceptional thickening efficiency, contributing to superior product texture and stability.


Another aspect that sets different types of PAC apart is their compatibility with various formulation ingredients and process conditions. Regular PAC demonstrates good compatibility with a wide range of substances, making it a versatile choice for formulators. Low viscosity PAC exhibits similar compatibility while offering tailored flow properties. High viscosity and ultra-high viscosity PAC are designed to integrate seamlessly into formulations that demand robust thickening under challenging conditions.

Application Insights:

The diverse range of polyanionic cellulose products offered by Unionchem caters to an array of applications across multiple industries. From enhancing the performance of drilling fluids in oil and gas exploration to optimizing the texture and stability of food products, PAC plays a crucial role in numerous processes.

In the oil drilling sector, regular PAC serves as an effective viscosifier and fluid loss control agent, contributing to efficient wellbore stability and drilling operations. Low viscosity PAC finds application in controlling fluid rheology and filtration control, particularly in scenarios where precise viscosity modulation is required.

In the food industry, regular PAC functions as a reliable thickener and stabilizer in products ranging from sauces and dressings to dairy items and baked goods. Low viscosity PAC offers formulators the flexibility to achieve desired flow properties in food formulations without compromising on stability and texture.

High viscosity and ultra-high viscosity PAC variants are instrumental in demanding industrial applications such as construction materials, where precise rheological control is essential for achieving desired product performance. These specialized products enable formulators to tailor the viscosity of formulations to exacting specifications, ensuring optimal product functionality and performance.
