PolyAnionic Cellulose PAC

Polyanionic Cellulose (PAC)  CAS No.: 9004-32-4 Molecular Formular:  [C6H7O2(OH)2CH2COONa]n Structural Formular:   Property: PAC is a kind of nonionic cellulose ether featured the properties of high purity, high DS, particularly high viscosity or low viscosity. These products are demi-natural polymer additive, thickening agent, filtrate reducer.PAC is an indispensable product for drilling mud making. It is high purity product; the water solution of this white powder is transparent and viscid. As water-soluble polymer, PAC 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 is a good drilling mud additive and also an important material for confecting well liquid, a high mud volume product that featured high acid-resistance and salt-resistance ability. PAC is a good filtrate reducer with the capacity of increasing viscosity and anti-high temperature (150°C) in the freshwater, seawater, or even saturated brine well-completion liquid. PAC is suitable for confecting the completion fluid with these 3 kinds of water above.Specification: Item Index PAC-LVPAC-HVAppearanceFreely flowable powderFreely flowable powderpH6.0-8.06.0-8.0Purity≥95%≥95%Moisture≤10%≤10%Degree of Substituation≥0.90≥0.90Viscosity brookfield (1%)≤50≥1500API fluid loseIncrease 0.57%≤25.0ml≤20.0mlIncrease 0.86%≤15.0ml≤15.0mlIncrease 1.14%≤10.0ml≤10.0mlYP ValueIncrease 0.57%≤0.5≥2.4Increase 0.86%≤1.0≥9.6Increase 1.14%≤1.5≥19.2NOTE: The parameters can be adjusted as per requirements.Usage: PAC-HV is for water-based drilling fluids, which can effectively reduces the filtration rate of many water-based oil and gas drilling fluids and may also be used to increase and stabilize viscosity to improve hole cleaning and suspension properties in a wide variety of fluid environment.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.Package and Storage: Packed in multiply paper bags or fiber drums (25KG), or as per customer requirement; keep dryKey Word: polyanionic cellulose, PAC, cellulose
