Quality Control

Our production of this copolyester adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical techniques including Gel Permeation Chromatography (GPC) for molecular weight distribution, Differential Scanning Calorimetry (DSC) for thermal properties, and FT-IR for structural identification. A comprehensive Certificate of Analysis (COA) detailing purity, acid value, hydroxyl value, and viscosity is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizing agents. As a polymeric material, prolonged exposure to high humidity should be avoided to prevent potential moisture absorption which could affect processing characteristics.
