Description

Poly(Maleic Anhydride-Alt-α-Olefin, C24-C28) is a high molecular weight copolymer synthesized from maleic anhydride and a long-chain C24-C28 α-olefin mixture. This product is valued for its ability to act as a highly effective dispersant and scale inhibitor in demanding industrial water treatment and oilfield applications. It is particularly sought after by formulators in the oil & gas, industrial cleaning, and detergent industries who require robust performance under high-temperature and high-salinity conditions. Its polymeric structure provides superior threshold inhibition and particle dispersion compared to conventional phosphonates.

Application

• Oilfield Scale Inhibition: Primary application for preventing the deposition of calcium carbonate, calcium sulfate, and barium sulfate scales in production wells, pipelines, and topside facilities.
• Industrial Water Treatment: Key component in cooling water and boiler water treatment programs to control scale and disperse suspended solids and sludge.
• Detergent & Cleaning Formulations: Acts as a builder and anti-redeposition agent in industrial and institutional cleaning products, enhancing performance in hard water.
• Dispersant for Minerals & Pigments: Used in processes requiring the stabilization of inorganic particles in aqueous suspensions, such as in paper manufacturing or ceramic processing.
• Textile Processing: Employed as a dispersing agent in dyeing and finishing operations to prevent spotting and ensure uniform color.
