Polyanionic Cellulose/ PAC For Oil Drilling API Grade CAS 9004-32-4

 

 

Description:
Polyanionic cellulose is a modified cellulose polymer obtained by chemically reacting cellulose with anionic groups. It is typically produced from wood pulp or cotton linter through a series of chemical modifications. The degree of substitution (DS) determines the extent of anionic substitution on the cellulose backbone.

Specification:

• Chemical formula: Variable, as it depends on the degree of substitution (DS) and the source of cellulose.
• CAS Number: 9004-32-4
• Appearance: Fine, white to off-white powder
• Solubility: Polyanionic cellulose is highly soluble in water, forming viscous solutions.

Application:

1. Oil and Gas Industry: Polyanionic cellulose is extensively used in the oil and gas industry as a drilling fluid additive. It acts as a viscosifier and fluid loss reducer in drilling muds, providing rheological control and stabilizing the fluid properties. PAC helps maintain wellbore stability and facilitates efficient drilling operations.

2. Construction Industry: Polyanionic cellulose finds application in the construction industry, particularly in cementing and mortar formulations. It acts as a thickener and water retention agent, improving workability, adhesion, and bond strength. PAC enhances the cohesion and consistency of cement-based materials.

3. Food Industry: Polyanionic cellulose is used as a food additive, primarily in the production of salad dressings, sauces, and dairy products. It functions as a thickener, stabilizer, and emulsifier, improving texture, viscosity, and shelf life. PAC helps prevent phase separation and enhances the overall sensory attributes of food products.

4. Pharmaceutical Industry: Polyanionic cellulose is employed in the pharmaceutical industry as an excipient in various formulations. It can act as a binder, disintegrant, and viscosity modifier in tablet formulations. PAC aids in tablet compression, dissolution, and controlled release of active ingredients.

Features:

1. Water Solubility: Polyanionic cellulose is highly soluble in water, forming clear and viscous solutions. This property allows for easy incorporation into aqueous systems and efficient dispersion throughout the medium.

2. Rheology Control: PAC exhibits excellent rheological properties, providing viscosity control and shear-thinning behavior. It imparts pseudoplasticity, allowing for easy pumping, mixing, and application in various industrial processes.

3. Fluid Loss Control: Polyanionic cellulose acts as a fluid loss reducer in drilling fluids, cement slurries, and other systems. It forms a thin, impermeable filter cake on surfaces, reducing fluid loss and maintaining desired fluid properties.

4. Thermal Stability: PAC exhibits good thermal stability, making it suitable for applications in high-temperature environments encountered in drilling operations or cementing processes.

5. Chemical Stability: Polyanionic cellulose shows resistance to chemical degradation and maintains its functionality in the presence of various chemicals and salts typically encountered in industrial processes.

 

 

Description:
Polyanionic cellulose (PAC) is a water-soluble polymer derived from cellulose through a chemical modification process. It is produced by reacting cellulose with anionic groups, typically carboxymethyl groups. This modification imparts unique properties to the cellulose, making it suitable for a range of applications.

Specifications:
The specifications of PAC can vary depending on the desired application and grade. The degree of substitution (DS), which represents the number of carboxymethyl groups per glucose unit in the cellulose chain, is an important specification parameter. PAC is available in different DS values, typically ranging from 0.5 to 1.5. The viscosity, purity, and moisture content are other important specifications that can vary based on specific requirements.

Application:

1. Oil and Gas Industry: PAC is extensively used in the oil and gas drilling industry as a viscosifier and fluid-loss control agent. It helps to increase the viscosity of drilling fluids, enhance their rheological properties, and reduce fluid loss during drilling operations.
2. Construction Industry: PAC is used in the construction industry as a thickener and water-retention agent in cement-based formulations. It improves the workability, consistency, and stability of cement slurries, mortars, and grouts.
3. Food Industry: PAC is used as a food additive, primarily as a thickening and stabilizing agent. It is commonly found in salad dressings, sauces, and other processed food products.
4. Pharmaceutical Industry: PAC is utilized in pharmaceutical formulations as a binder, disintegrant, or suspension agent. It helps to improve the flow properties, compressibility, and dissolution characteristics of tablets and capsules.
5. Personal Care Products: PAC is used in personal care and cosmetic products as a thickener, emulsion stabilizer, and water-binding agent. It can be found in products like shampoos, lotions, and creams.

Features:

1. Water Solubility: PAC is readily soluble in water, allowing for easy incorporation into various formulations and systems.
2. Rheology Control: PAC imparts viscosity and rheological control, making it useful in applications requiring thickening, stabilization, or control of fluid flow.
3. Filtration Control: PAC acts as a fluid-loss control agent, reducing the loss of fluid into porous formations during drilling or cementing processes.
4. Stability: PAC provides stability to formulations, improving their resistance to temperature, pH variations, and mechanical stress.
5. Compatibility: PAC is compatible with a wide range of other additives and ingredients, allowing for versatile formulation possibilities.

 

Products Description

Polyanionic Cellulose: Enhancing Performance and Efficiency

 

PAC is a water-soluble polymer derived from cellulose, a natural polymer found in plant cell walls. Through a meticulous manufacturing process, we create PAC with exceptional properties, making it an indispensable additive in numerous applications.

 

In the oil and gas industry, Polyanionic Cellulose plays a vital role as a highly effective fluid loss control agent. It helps to maintain the stability and integrity of drilling fluids, preventing excessive fluid loss during drilling operations. Our PAC products exhibit excellent viscosity and filtration control, ensuring optimal drilling performance and reducing operational costs.

 

Moreover, Polyanionic Cellulose finds extensive usage in the paper and pulp industry. As an effective paper additive, PAC enhances the paper's strength, stability, and retention of fillers and fibers. It improves the formation of the paper sheet, increases the paper's resistance to water and chemicals, and optimizes the overall papermaking process.

 

In the food and beverage industry, Polyanionic Cellulose serves as a versatile ingredient, providing numerous benefits. It acts as an efficient stabilizer and thickener, enhancing the texture and stability of various food products such as sauces, dressings, and dairy items. Its ability to control water retention and improve mouthfeel makes it a valuable component in many food formulations.
