Wholesale PAC Polyanionic Cellulose

Features

PAC Polyanionic Cellulose is a high-performance anionic water-soluble cellulose ether that is odorless, tasteless and non-toxic. It appears as a white or off-white free-flowing powder that dissolves quickly in cold or hot water to form a uniform and stable viscous solution. It boasts a variety of excellent properties such as thickening, suspending, emulsifying, dispersing, water retention and salt resistance, and is widely used in oilfield drilling, daily chemical products, food processing, papermaking, textile printing and dyeing, water treatment and other fields.

Market Prospects

With the continuous development of the global economy and the rising demand for high-performance water-soluble polymers in industries such as oilfield development, daily chemicals, and water treatment, the market demand for PAC Polyanionic Cellulose will keep growing steadily. With the continuous advancement of scientific and technological innovation, our PAC Polyanionic Cellulose production technology and product quality will be further optimized and upgraded. Through process improvement and product performance enhancement, the application stability and adaptability of PAC Polyanionic Cellulose will be more outstanding, and its application fields will be further expanded to emerging industries. This will bring new growth drivers and development opportunities to the PAC Polyanionic Cellulose market.

Polyanionic Cellulose Manufacturing Process

As a cellulose factory, we select high-quality refined cellulose and high-purity anionic etherifying agents, and conduct strict raw material pretreatment to optimize reaction temperature and pressure conditions. Under a precisely controlled environment, cellulose is subjected to etherification and modification reactions with specific anionic reagents to form the polyanionic cellulose (PAC) molecular structure. After the reaction, acid-base neutralization treatment is performed to remove excess reactants and by-products, and product purity is ensured through multiple countercurrent washings. The product is dried to a standard moisture content and then crushed and sieved to the required particle size to ensure uniform fineness of the finished product. Strict testing is performed on various performance indicators of PAC Polyanionic Cellulose, including viscosity, substitution degree, salt resistance, pH value, etc., to ensure full compliance with industry and customer standards. Professional moisture-proof and anti-caking packaging materials are used to protect the product from moisture, dust and other external environmental influences, ensuring safe storage and transportation.

Use Precautions

1The optimal addition amount of PAC Polyanionic Cellulose varies in different applications. Please be sure to weigh it accurately according to the specific application scenario and formula requirements, and fully disperse and dissolve it under the recommended temperature and stirring conditions to avoid agglomeration or incomplete dissolution affecting the use effect.

2 The performance of PAC Polyanionic Cellulose is affected to a certain extent by the pH value and ionic strength of the system. Before use, please confirm and adjust the pH value and ion concentration of the working solution to the appropriate range to ensure the stability and comprehensive performance of PAC.

3 High temperature may cause degradation of PAC Polyanionic Cellulose and reduce its viscosity and stability, while low temperature may slow down its dissolution rate and affect dispersion uniformity. Therefore, extreme temperatures should be avoided as much as possible during storage, transportation and use, and kept within the recommended temperature range.

4 In a multi-component system, the order of adding PAC Polyanionic Cellulose has an important influence on the performance of the final product. It is generally recommended to add PAC after other solid components are evenly dispersed, and sprinkle it slowly and uniformly while maintaining continuous and sufficient stirring to prevent local agglomeration.

Characteristics

Excellent Water Solubility:

Anionic groups (such as carboxymethyl groups) are introduced into the PAC molecule. These groups significantly enhance the hydrophilicity and interaction between the molecule and water molecules, allowing PAC to quickly dissolve in both cold and hot water to form a uniform, stable viscous solution without obvious precipitation.

Outstanding Salt Resistance:

The polyanionic structure of PAC enables it to form a stable hydration layer on the molecular surface. This structure makes PAC less susceptible to the influence of metal ions in the solution, and it can maintain good viscosity and stability even in high-salt systems (such as brine), which is superior to many ordinary cellulose ethers.

Excellent Thickening and Suspending Ability:

PAC has a long and flexible molecular chain, which can entangle with each other to form a dense three-dimensional network structure in aqueous solution. This network structure can effectively trap water molecules to significantly increase solution viscosity, and the voids in the network can stably suspend solid particles, preventing sedimentation and stratification.

Good pH Stability:

The anionic functional groups in PAC molecules have strong chemical stability. Under a wide pH range (typically pH 3-11), the molecular structure of PAC will not be damaged, and it can maintain stable thickening, suspending and other key performances, adapting to various acidic and alkaline working environments.

Main Function

Construction Industry
PAC is a high-performance additive for cement mortar, boosting water retention, adhesion and plasticity of mortar, preventing cracking and bleeding. It enhances crack resistance, impermeability and compressive strength of cement products, extends mortar open time and improves construction efficiency.

Coating Industry
As thickener, suspending agent and stabilizer in coatings, PAC regulates viscosity, improves pigment suspension stability and prevents component precipitation and delamination. It enhances paint’s brushability and leveling, making the coating film denser, more water-resistant and scrub-resistant, and extending coating service life.

Pharmaceutical Industry
PAC is a high-quality excipient for tablets and capsules, acting as binder, disintegrant and sustained-release material. It improves tablet hardness, ensures uniform distribution of active ingredients, controls drug release rate to boost bioavailability, and optimizes the taste and storage stability of preparations.

Food Industry
As a safe food additive, PAC is used as thickener, stabilizer and emulsifier in dairy, beverages, frozen foods, etc. It improves food viscosity and stability, prevents separation and water loss, enhances water retention and taste for a delicate texture, and extends food shelf life to maintain original flavor.

Other Industries
PAC is widely used in petroleum, daily chemicals, textiles and other fields. It is a key drilling fluid additive in petroleum industry for filtration loss reduction; in other fields, it acts as thickener and dispersant to improve product performance, and provides customized solutions for different industrial needs.
