Description:
PHPA EHV is a very high molecular weight partially hydrolyzed polyacrylamide (PHPA) polymer. It works as an environmentally friendly synthetic soil stabilizer which is designed to be used in place of bentonite as polymer drilling fluid for a variety of slurry drilling, trenching and walling applications in the geo-construction industry.

Application:
PHPA EHV is very useful in slurry trenching, diaphragm walls, drilled shafts/bored piles, and tunneling application. Very small dosage will provide a clear, solid-free, viscous borehole stabilizing fluid, meanwhile stablizing the reactive clays and controlling fluids loss.

Physical requirements:
