High molecular weight drilling polymer for borehole stability, lubrication and improved core recovery. Formerly HPM MULTIPOL 7000.
MF-CR650 is a high molecular weight granular copolymer designed for diamond drilling and water-based drilling systems. Even at low concentrations, it produces a clear, highly viscous fluid that improves borehole stability, lubrication and core recovery.
MF-CR650 mixes easily and is compatible with most drilling polymers, bentonite and lubricants, making it an effective solution for reactive clays, shales and loose formations.
MF-CR650 is used to stabilize reactive clays and shales while providing excellent lubrication during diamond drilling. It forms a protective polymer film on the borehole walls and core, helping reduce water invasion and improve stability in loose or sandy formations.
