PAC Polyanionic Cellulose

1.PAC (Polyanionic Cellulose) 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.
2.PAC is an indispensable product for drilling mud making. PAC is high purity product; the water solution of this white 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.
3.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. It 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. It is suitable for confecting the completion fluid with these 3 kinds of water above.
Main applications
This product is used in petroleum, natural gas and drilling wells etc.  engineering; synthetic detergent and soap industry, textile, printing and dyeing, papermaking, food, medicine, building  coating, daily chemicals, leather and other industries;
It can be inhibitor in formaldehyde production and storage; in addition, it also can be used in the ship, electronic,  ship welding electrodes, refrigerating and metal processing.
