Poly Anionic Cellulose PAC Factory High Quality China Suppliers
Poly Anionic Cellulose (PAC) is a high-performance, water-soluble cellulose ether derivative engineered through the chemical modification of natural cellulose. Typically supplied as a sodium salt, this versatile polymer is a critical additive in complex industrial environments, particularly renowned for its superior performance in oil drilling operations, saltwater wells, and offshore exploration.
Characterized as a white to light yellow odorless powder, PAC offers exceptional solubility in both cold and hot water. It serves as a high-efficiency fluid loss reducer and thickener, providing unmatched stability and compatibility across various industrial applications, from papermaking and daily chemicals to advanced textile finishing and high-end coatings.

Frequently Asked Questions
Q: What makes PAC more effective than CMC in oil drilling?
PAC possesses a higher degree of substitution and better stability in high-temperature and saltwater environments, allowing it to achieve the same fluid loss control as CMC using only 30%-60% of the quantity.
Q: How should Poly Anionic Cellulose be stored to ensure longevity?
It should be stored in a cool, dry place away from direct sunlight and pressure. Unopened multi-layer polyethylene-lined bags can be stored for several years.
Q: Can PAC be used in the cosmetics and daily chemical industry?
Yes, it is widely used as a thickener in toothpaste for consistency and as a hydrosol in cosmetics for emulsification and stabilization.
Q: What is the role of PAC in the papermaking process?
In papermaking, PAC controls the rheology of coatings, improves pigment dispersibility, increases paper stiffness and smoothness, and reduces curling.
Q: Is Poly Anionic Cellulose compatible with other resins?
Yes, PAC shows excellent compatibility with water-soluble glues, resins, and other cellulose ethers, making it an ideal additive for complex coatings.
Q: How does PAC improve textile weaving efficiency?
As a sizing agent, it replaces starch to improve the strength and bendability of the size film, ensuring uniform fiber bonding and higher weaving efficiency.
