We have helped multiple customers, from small end users to large Fortune 500 customers, with their Polyanionic Cellulose supply requirements and can ship bulk and various packaged products to meet such needs.

PAC (Polyanionic Cellulose) is a kind of nonionic cellulose ether with the properties of high purity, high DS, particularly high viscosity or low viscosity. These products are semi-natural polymer additive, thickening agent, filtrate reducer.

PAC is an indispensable product for drilling mud making. PAC is high purity product, the water solution of this powder is transparent and viscid. As water-soluble polymer, it dissolves immediately in cold/hot water and can be used as a thickening agent, rheology controller, bond, stabilizer, colloid protector, suspending agent, and filtrate reducer.

PAC-LV is for use in solids-laden, water-based drilling fluids, which can effectively reduces the filtration rate of many water-based drilling fluids, without causing significant increases in viscosity or gel strength.

PAC R is a cost-effective additive to reduce API filtration rate of many water based drilling fluids including freshwater, seawater, saturated saltwater and solids-free brines, native mud, flocculated mud, inhibited mud and contaminated systems. PAC R increases and stabilizes viscosity to improve rheology, wellhole cleaning and suspension property by coating and encapsulating cuttings and solids of drilling fluids. PAC R is effective over a wide range of pH environments. It lubricates solids in the system, improve wallcake characteristics and reduces the potential for stuck pipe.
