APPLICATIONS

PAC-LV is highly water soluble and can be used as thickener, binder, stabilizer, protective colloid, suspending
aid and water retention agent. It is the key ingredient for fresh water slurry and seawater slurry in oil well-drilling. It
can be used for the fresh water, seawater or saturated brine well-completion liquids. It has excellent heat stability,
and is able to function as thickener under the temperature of 150℃.
