Quality Control

Our Phosphonic Acid, Ethenyl-, Bis(2-Chloroethyl) Ester, Polymer With Dimethyl Methylphosphonate undergoes rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards for flame retardant additives. Certificates of Analysis (COA) are available upon request, detailing key parameters such as phosphorus content, viscosity, and residual monomer levels. Our quality management system supports traceability and meets the demands of global supply chains.

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). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be opaque or stored in dark conditions. Separate from strong oxidizing agents and bases.
