Quality Control

Our production of Naphthalenesulfonic Acid, Sodium Salt, Polymer With Formaldehyde And 4,4-Sulfonylbisphenol adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. The manufacturing process is controlled under a quality system compliant with ISO standards. All products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing key parameters such as sulfonation degree, molecular weight distribution, and solids content are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect flow properties and performance. Keep away from incompatible materials such as strong oxidizing agents.
