Quality Control

Our Carbon Dioxide Polymer With Ethylene Oxide is manufactured under stringent quality management systems. Each batch is characterized for critical parameters including molecular weight distribution, residual monomer content, and thermal properties to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) detailing specific results are provided with every shipment. We support compliance with relevant research and industrial standards.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and potential degradation.
