Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters. Quality is verified through a suite of analytical tests including GPC (Gel Permeation Chromatography) for molecular weight distribution, FT-IR for structural confirmation, and thermal analysis (DSC/TGA). A comprehensive Certificate of Analysis (COA) detailing specifications for viscosity, silicone content, thermal transitions, and clarity 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep away from strong acids, bases, and oxidizing agents to prevent degradation of the polymer chain.
