Description

Poly(Maleic Anhydride-Alt-1-Octadecene) is a high-performance alternating copolymer known for its excellent dispersing and scale-inhibiting properties. This versatile polymer is crucial for enhancing process efficiency and product stability in demanding industrial applications. It is primarily sought after by manufacturers in the water treatment, detergent, and oilfield chemical industries for its ability to control mineral deposits and stabilize formulations.

Application

• Industrial Water Treatment: Acts as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Used as a builder and anti-redeposition agent in laundry and dishwashing detergents to improve cleaning efficiency and prevent soil from re-depositing on fabrics.
• Oilfield Chemicals: Serves as a critical component in scale squeeze treatments and production chemicals to prevent mineral scale formation in downhole and topside equipment.
• Pigment & Dye Dispersant: Provides superior stabilization for inorganic pigments and dyes in aqueous systems, preventing agglomeration and settling.
• Paper & Pulp Industry: Functions as a dispersant and deposit control agent to improve pulp processing and paper quality.
• Textile Auxiliaries: Employed in scouring and dyeing processes to enhance wetting, emulsification, and dispersion of impurities.

Quality Control

Our Poly(Maleic Anhydride-Alt-1-Octadecene) is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assay, molecular weight distribution, and residual monomer content. Certificates of Analysis (COA) documenting full specifications are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
