Quality Control

Our production of this specialty copolymer adheres to strict quality management systems. Each batch is characterized for key parameters including molecular weight distribution, thermal transition temperatures, and intrinsic viscosity to ensure batch-to-batch consistency. Certificates of Analysis (COA) detailing these specifications are provided and 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect processing and final properties.
