APPLICATIONS

PAC-HV is highly water soluble and can be used as thickener, binder, stabilizer, protective colloid, suspending
aid and water retention agent. It is a good mud slurry treatment agent for oil well-drilling and 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℃.
