Quality Control

Our Poly(1,3-Butanedioladipicacidester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and performance characteristics. Certificates of Analysis (COA) detailing key specifications such as acid value, hydroxyl value, and viscosity are available upon request to support your quality assurance protocols.

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 product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product properties.
