Liquid PHPA

PHPA liquid is a partially hydrolyzed polyacrylamide polymer in emulsion form that is used as a fluid loss reducer, viscosifier, and shale stabilizer in water-based drilling fluids. It is a high molecular weight anionic polymer that forms a protective layer on the shale surfaces and prevents their dispersion and swelling.
