Introduction
Polymalic acid is a polymer whose chemical structure is made up of malic acid molecules linked by ester bonds. The following is a brief introduction to the properties, uses, preparation methods and safety information of polymalic acid:Quality:- Polymalic acid is a colorless, odorless solid with good solubility.- It forms a colloidal solution in water.- Polymalic acid has excellent biocompatibility and degradability.Use:- Polymalic acid can also be used in agricultural fields such as the preparation of fertilizers, soil remediation, etc.Preparation method:- Polymalic acid is usually prepared by polymerization reactions.- Common preparation methods include epoxy ring-opening polymerization, monomer condensation polymerization, etc.Safety Information:- Polymalic acid is generally considered harmless, but specific safety information needs to be judged based on usage and specific application scenarios.- During use, correct experimental practices should be observed, avoiding contact with skin, eyes, and inhaling dust.- In case of accidental ingestion or contact, seek medical help immediately and bring the appropriate material safety data sheet.
Application
Polymaleic acid (CAS 26099-09-2) is a low molecular weight water-soluble polymer widely used as an antiscalant and dispersant in industrial water treatment. It effectively inhibits the formation of calcium carbonate, calcium sulfate, and calcium phosphate scales in cooling water systems, boilers, and reverse osmosis units. Its strong thermal stability and resistance to hydrolysis allow reliable performance under high temperature and alkaline conditions. Polymaleic acid also disperses suspended solids, prevents sludge agglomeration, and works synergistically with organic phosphonates and zinc salts to enhance corrosion inhibition. In oilfield applications, it controls scale in injection and production wells. Additionally, it is used in textile processing and detergent formulations. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high-purity polymaleic acid with flexible scaling from R&D to commercial tons.
