Partially Hydrolyzed Polyacrylamide (PHPA)

PHPA is a high molecular weight polymer with a moderate anionic charge for drillingmud additive. It can be used in both industrial and oil field drilling applicationand it is usable in both fresh water and brines. It can be used in high temperature. Applications:1) Shale stabilization 2) Viscosifier 3) Friction reduction 4) Fluid loss control 5) Lubrication Specifications:1) Appearance: off white powder 2) Degree of charge: 15 - 45% 3) Molecular weight: 5 - 20 4) Solid content: 89% min.  To obtain homogeneous solution, efficient dispersion is necessary. The most convenientmethod of dispersing these products is with a polymer eductor or a commerciallyavailable dry powder feeder unit. Solution should be made up at 0.1 - 0.3%solid. Make-up water temperature should be between 10 and 40
