Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like molecular weight distribution, color, and thermal properties. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC), Differential Scanning Calorimetry (DSC), and FT-IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, viscosity, and other key specifications 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 the original packaging sealed until use to prevent moisture absorption, which can affect processing and final properties.
