Quality Control

Our production of 1,3-Dioxolan-2-One Polymer With 1,6-Hexanediol And 1,5-Pentanediol adheres to stringent quality management protocols. Each batch undergoes rigorous testing to ensure consistent properties such as hydroxyl value, molecular weight distribution, viscosity, and color. Certificates of Analysis (COA) detailing all specifications are provided to guarantee compliance with your technical requirements and support your own quality assurance processes.

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 under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and potential degradation.
