What is partially hydrolyzed polyacrylamide (PHPA) based high molecular weight drilling polymer?

Partially Hydrolyzed Polyacrylamide (PHPA) based high molecular weight drilling polymer for use in controlling of fluid loss and increasing drilling mud viscosity and removal of colloidal from deep drilling foundations such as diaphragm walls, piling concretes, etc.

Are PHPA drilling polymers toxic?

Key Features and Benefits: Chemtex's PHPA Drilling Polymers when tested for its toxicity level, were found eco-friendly and when compared to its contemporaries such as Bentonites (Al2H2O6Si). They may not be hazardous to soil but is highly toxic to aquatic life and hence do not find its use in sites beside water bodies.

Does ChemTex drill polymer cause marine toxicity?

Chemtex's Drilling Polymer has neither marine toxicity nor does it affect farming land if disposed. Moreover, it is used at only one-tenth concentration of bentonite and can be easily broken down with normal bleaching solution.
