Quality Control

Our production of this advanced polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical applications. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC) for molecular weight distribution, Fourier-Transform Infrared Spectroscopy (FT-IR) for structural confirmation, and thermal analysis (DSC/TGA). A comprehensive Certificate of Analysis (COA) detailing purity, viscosity, solid content, and functional group content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maintain stability and prevent premature polymerization or viscosity increase. The product is moisture-sensitive; keep the container tightly sealed when not in use. Keep away from heat sources and incompatible materials.
