Applications & Uses

Description

Potassium polyacrylate (K-PAM) is a carboxyl-containing potassium polyacrylamide derivative. It has high water absorption, low production cost, simple processing technology, stable product quality, and long-term storage without deterioration.

Uses

Potassium polyacrylate is used for shear thinning and anti-slump flocculation of downhole non-dispersed low-solid mud and polymer systems.
