Quality Control

Our Combiflex is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling. Certificates of Analysis (COA) documenting all test results are provided and can be tailored to meet specific customer or regulatory requirements. We are committed to supplying material that meets the high standards demanded by the polymer and specialty chemical industries.

Storage

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