Quality Control

Our Poly(Trimethylene Succinate) is manufactured under stringent quality management systems. Each batch undergoes comprehensive analysis to ensure consistent molecular weight, viscosity, thermal properties, and purity, meeting the requirements for advanced material applications. Certificates of Analysis (COA) detailing key parameters such as inherent viscosity, melting point, and residual monomer content are available upon request.

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 container tightly sealed to prevent moisture absorption, which can affect processing and properties.
