What is Polyanionic Cellulose? Polyanionic cellulose (PAC) is a water-soluble cellulose derivative that is widely used as a thickening agent, stabilizer, and filtration control additive in various industries, particularly in the oil and gas sector. Here are some key points about polyanionic cellulose: 1). Chemical Structure: Polyanionic cellulose is derived from cellulose, a natural polymer found in the cell walls of plants. Through a chemical modification process, carboxyl groups (-COOH) are introduced into the cellulose structure, resulting in a negatively charged polymer with excellent water solubility. 2). Oil and Gas Industry Applications: PAC is extensively used in the oil and gas sector, particularly in drilling fluids and completion fluids. It helps control the rheological properties of the drilling mud, including viscosity, filtration control, and fluid loss prevention. PAC improves the carrying capacity of the drilling fluid, assists in hole cleaning, and enhances the overall drilling efficiency. 3). Other Applications: PAC finds applications in various other industries as well. It is used as a thickening and stabilizing agent in the construction industry for applications like cementing, mortar, and grout formulations. PAC is also employed in the textile industry for printing and dyeing processes, as well as in the paper industry to improve paper strength and retention of fillers. 4). Safety Considerations: Polyanionic cellulose is generally considered safe for use in the intended applications when used in accordance with recommended guidelines and industry practices. However, like any chemical substance, appropriate safety precautions should be followed, including handling with care, avoiding inhalation or direct contact with eyes or skin, and adhering to relevant safety data sheets. Polyanionic cellulose’s water solubility, thickening properties, and ability to control fluid filtration make it a valuable additive in various industries, particularly in the oil and gas sector. Its versatility and beneficial properties contribute to improved performance and efficiency in a range of applications.

Our trade process spreads across CIF, FOB, TTO, and TTT, depending on the buyer’s preference. Here’s what they entail: 1). Cost Insurance and Freight (CIF): Here, the seller will handle everything from loading the vessel, paying for insurance, and sending the product to wherever the buyer wants it delivered. 2). Freight On Board (FOB): Here, the seller pays for the transportation of the goods to the port of shipment, plus loading costs, while the buyer pays the cost of marine freight transport, insurance, unloading, and transportation from the originating port to the final destination. 3). Tanker Take Over (TTO): Here, the buyer will take over the vessel, offload the product at their destination, and return it. 4). Tanker To Tanker (TTT): Here, the buyer uses their own vessel, long sides with the seller’s vessel, and then the cargo is transshipped when the transaction is fully settled.
