    Feature

    Phosphino Carboxylic Acid (PCA) is an organophosphorus chemical that contains both phosphinic acid (-P(OH)₂) or phosphonic acid (-PO(OH)₂) and carboxylic acid (-COOH) functional groups in a single molecule.

    Phosphino Carboxylic Acid PCA is a colorless, transparent liquid with a light odor and excellent performance. The pH range is 3 to 3.5. This ingredient is essential for water treatment, PCA is designed to improve water quality and is an important substance in the water purification process.
    As a leader in the chemical industry, our company strictly controls product quality to ensure that each batch of products meets the highest purity and standards.

    What is phosphino carboxylic acid used for?

    Phosphonic acid has the ability to completely dissolve in water. This unique solubility ensures that PCA can be used in various municipal water treatments as well as industrial water treatments.
    It can significantly improve the overall quality of water.

    1. Used as a scale inhibitor. Especially suitable for calcium carbonate and calcium sulfate. Suitable for boiler water, cooling water systems, reverse osmosis systems
    2. Detergent.
      Prevent metal ions from depositing on the surface and improve performance in hard water.
    3. Industrial cleaner.
