Quality Control

Our production of this advanced polymer adheres to stringent quality management systems. Every batch undergoes rigorous analytical testing, including gel permeation chromatography (GPC) for molecular weight distribution, thermal analysis (DSC/TGA) for curing behavior and stability, and spectroscopic identification (FT-IR). We provide comprehensive Certificates of Analysis (COA) with batch-specific data to ensure traceability and compliance with your formulation requirements.

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). Keep away from heat sources and incompatible materials such as strong acids and oxidizing agents. Under these conditions, the product is typically stable for 24 months from the date of manufacture.
