Quality Control

Our polymer products are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including molecular weight distribution, thermal transition points, and functional group content. Certificates of Analysis (COA) detailing specific test results are provided with every shipment. We support compliance with relevant industry standards, including ISO 9001, and can tailor specifications to meet specific customer requirements for medical, automotive, or industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept away from excessive humidity and incompatible materials such as strong acids, bases, and oxidizing agents.
